Armenia: Noah’s legacy is in safe hands

A journey to Armenia through the stunning history of Karas winery, where Oenodia will be soon commissioning a brand-new unit.

Where does the vine come from? Where did Noah plant the first one? Where was Vitis vinifera first found in its primitive form? Minor Asia, Georgia, Armenia? Fascinating questions!

Let’s travel to Armenia a moment, where Oenodia will be installing the country’s first STARS unit next July. A discreet country, that has stayed out of the wine world’ turmoil, but whose oenological revival, initiated 20 years ago, is more than worth the interest.


With substantial export sales, Karas winery is a major actor of that rebirth. Gabriel Rogel, its adventurous Argentinian winemaker, now working for 7 years at Karas, has kindly agreed to share his experience and to give us some insight of the Armenian wine industry.


  • What was Armenian viticulture back in the 90s?

At the fall of the Soviet Union, while Georgia was principally producing wine, viticulture was mostly dedicated to brandy in Armenia. The little amount of wine that was produced was typically entry-level sweet red and was sold locally”.


  • In that context, how came the first spark of the Karas project?

Karas is all about a family coming back home. After a stunning history in Argentina, and fortified by the earlier success of Bodega del Fin del Mundo in Neuquén, the Eurnekian family decided to renew its roots within its homeland.

Back in 2002, the initial project entailed planting vines to provide premium grapes for the brandy industry. The region of Armavir happens to be the idyllic place, and its unique volcanic terroir prompted the family to try a couple fermentations, first with local grapes varieties, then planting international ones. The successful results of those trials were the spark to move forward and our first wine was released in 2010.”


  • Do you intend to promote local grape varieties?

We do believe in local varieties and take advantage of their diversity in many blends, combined with international varieties.

More than most, the Areni is definitely the emblematic red variety in Armenia. Its delicate profile and herbal freshness show a great potential that we keep on mastering, year after year, by selecting our own plant material from older vines.

Another major red variety is the Sireni. Colorful and full-bodied, it makes a singular synergy blended with the Areni.


  • How does this choice influence your offer and how does it fit with your sales expectations?

Both our blends and mono-varietals are a success, on the national as well as on the international market, and it’s actually difficult to keep up with the demand.

If 60% of our sales goes national, we intend to swap that figure to the export market in a few years. The Armenian diaspora is widespread, especially in the USA and Western Europe, and especially faithful to Armenian wines. That’s obviously the channels we’re aiming at.


  • What’s your vision for the Armenian wine industry in the near future?

Armenia holds many terroirs and varieties, and we’re constantly learning to make the most of its incredible potential.

Wine history is here more than anywhere, and today we are reinventing winemaking to share, worldwide, the best our terroirs have to offer.

Karas in not alone. New investors, renown consultants and diligent winemakers have been working hard lately and all contribute to the rebirth and recognition of Armenian wines.

STARSXF® offers unparalleled efficiency. Three days of plate and frame filtering and a month of cold stability was accomplished in 5 hours!

This, according to Jason McConnell, Owner and Winemaker at RIVINO Winery, following his first time utilizing Oenodia’s STARSXF®, which streamlines wine stabilization with crossflow filtration in a single pass.


April 22, 2020.  Napa, CA.  STARSXF® is part of the STARS Line of technologies, pairing OENODIA’s specific crossflow filter with their STARSStab unit.   Over the past few months, several winemakers have employed the process through OENODIA’s STARS Mobile Service.  A few have offered insight into their experience and its effectiveness in delivering a continuous process of filtration directly followed by tartrate stabilization.

Jason McConnell was among these winemakers who utilized the technology.  He had seen it used at another winery and was impressed by how quickly and efficiently the cold stability process could be conducted.  Ashley Highland, Consultant Winemaker from J Curtis, who also utilized the technology for the first time, had been watching STARSXF® for a while.  “When I stepped into a friend’s winery in Washington and they were running their STARSXF® machine, I noticed how polished the wines looked and thought how wonderful it was that you can filter and stabilize in one pass.”

By merging the two processes into a single pass, STARSXF® delivers the well-known advantages of both technologies, eliminating DE and KHT seeding but also reducing drastically both the cold stabilization stage, and the wine losses.  In addition, from a planning perspective, when you need a mobile service to handle both the crossflow filtration and the tartaric stabilization of your wines, it is much easier to plan when you have only one contact person.

“The process sped up the preparation time needed pre-bottling and left the wine more whole organoleptically” said Ashley.   McConnell agreed, “We were able to get our wines to market faster than ever before.” He added “The wines tasted great and have over the months since the trial, tasted even better.”

STARSXF® also offers operational flexibility and easier tank management while retaining respect for the wines.  “I have had tanks that were on cold for 6+ weeks and the DO pick-up they had, regardless of daily gassing, was too big for comfort.” Ashley said.  “In addition to the draw on electricity” she added “I felt like there must be a better way for the wine and the environment.  It is hard on a wine to be held so cold and then seeded, I would sometimes see cot strip the wine in a small way.”

Following her experience with STARSXF® Ashley noted “I purchase wine from all over the West coast and have to tanker the wine to a central location for blending and finishing. To have one less move is better for the wine’s quality. It was an extreme cost savings to crossflow and cold stab at the same time. Less than half the cost of filtration and traditional cold stabilization. Better for the wine and better for energy consumption”.

In conclusion, with respect to overall satisfaction both Jason and Ashley were conclusive in their opinion.  Ashland was “beyond satisfied and I will use this in the future on all my wines where applicable.”

Jason went further adding: “I was completely satisfied with all aspects of the operation and hopefully will be able to purchase a unit for our new winemaking facility. Until that happens we will also be return customers for using their mobile service.  I would definitely recommend this service and/or purchasing this equipment.”

Vendanges 2020 au Brésil : un record de qualité

La période des vendanges dans l’Etat de Rio Grande do Sul, responsable de 90% de la production nationale, est une des plus longues au monde. Coup de projecteur.

Chaque année, les vendanges commencent en décembre avec les cépages précoces – Pinot noir, Chardonnay et Riesling itálico – destinés aux vins de base des effervescents brésiliens répondant au doux nom d’ »espumantes ». Janvier voit rentrer dans les caves les grappes de Pinot noir et de Chardonnay destinées aux vins tranquilles. Le tour du Merlot vient pendant les premières semaines de février ; enfin, fin février et début mars, le Marselan, et le Cabernet et le Tannat sont récoltés.

Une récolte tardive

La récolte 2019-2020 a été tardive en raison de l’été brésilien – lequel, ne vous trompez pas, commence en décembre – caractérisé par sa sécheresse avec des pluies faibles, sporadiques et localisées, qui ont permis la maturation complète et l’atteinte d’un bon équilibre sucre-acide. Le taux moyen de sucre est passé de 13°Babo en 2019 à 16°Babo en 2020 (soit 14,5 et 17,8° Brix respectivement) « C’est la meilleure vendange des 20 dernières années » – commente Mauro Zanus, agronome à Embrapa Uva e Vinho (équivalent brésilien de l’INRA).


Moindre mais meilleure

D’autre part, 695 millions de kilos de raisin ont été vendangés cette année dans l’État de Rio Grande do Sul, soit 11% de moins qu’en 2019. Cette baisse de production est due principalement à la coulure, phénomène de non-fécondation d’une partie des fleurs, à cause de pluies lors de la floraison, entre octobre et novembre. La joie des œnologues brésiliens de la région, qui considèrent la vendange de 2020 comme une des meilleures des dernières années, reste néanmoins intacte. On vous sert un verre ?


Um abraço,

Le vin au Brésil : que savez-vous de ce marché émergent ?

Avec un marché domestique dynamique et des consommateurs aventureux, en quête de nouveauté et de qualité, la production de vin brésilienne trouve un moteur naturel, notamment pour ses vins effervescents « espumantes », de plus en plus appréciés aussi bien dans leur pays natal qu’à l’extérieur.

Renata et Fabien (Oenodia) participant à la « Wine South America. Sept 2019

Une faible consommation domestique pour un important pays producteur

7% des Brésiliens majeurs consomment du vin pratiquement tous les jours, soit 1,6 million de personnes de consommateurs quotidiens. Malgré une faible consommation domestique (seulement 2L en moyenne par habitant et par an, face aux 50L français ou 59L portugais), soit 3,3 millions hL annuels, le Brésil est un pays producteur important, le 13ème au monde selon l’OIV, avec une production d’environ 4 millions hL en 2019. 90% de la production brésilienne de vin est réalisée dans l’Etat de Rio Grande do Sul (RS), situé au sud du pays, dans lequel Ibravin décompte plus de 680 producteurs de vin3.

Le boom des effervescents

Si le vin ne fait pas encore partie de la culture au Brésil, les dernières nouvelles du marché indiquent que sa dégustation y devient peu à peu une habitude. Selon une étude réalisée par Wine Intelligence pour l’Institut brésilien du vin (Ibravin), le nombre de consommateurs réguliers a continué à augmenter au cours de l’année dernière, atteignant 32 millions de personnes. Cette tendance à la hausse portée principalement par le boom du marché domestique des vins rosés (de 2,1% du marché national en 2015 à 5,1% en 2019) et effervescents (« espumantes » et autres muscats nationaux), de plus en plus reconnus pour leur haute qualité. De manière globale, la consommation de vin continuera à croître dans les marchés émergents comme le Brésil, à l’inverse des marchés développés, où une baisse est anticipée2.

En quête de nouveauté

Ces chiffres révèlent le potentiel du marché brésilien, dont les consommateurs, considérés comme aventureux, sont en quête de nouveauté et de qualité4. Un potentiel de marché à explorer chaque année à Bento-Goncalves au salon Wine South America, auquel l’équipe d’Oenodia Brasil s’est rendue en septembre 2019.

SITEVI 2019/OENODIA : le futur est déjà là

L’innovation doit être inscrite dans les gènes d’OENODIA : cette année, en préparation du SITEVI – l’incontournable rendez-vous montpellierain de la filière viti-vinicole, l’équipe d’OENODIA a senti un besoin impérieux de renouveler sa manière de présenter les solutions de la gamme Stars®. Il s’agissait de trouver un écrin à la hauteur de la nature hautement technologique et qualitative des équipements OENODIA : le choix s’est porté sur une vitrine holographique et une table tactile 4K.

La vitrine holographique a mis en scène le dernier investissement de la maison Mumm, à savoir une ligne complète de procédés OENODIA pour réaliser l’ensemble de la préparation à la mise en bouteille (stabilisation tartrique et filtration tangentielle) en un seul passage : une unité STARS120 couplée à un filtre tangentiel de 180m². L’émerveillement était au rendez-vous, avec des visiteurs intrigués et curieux venus sur le stand pour percer le mystère. L’innovation est allée de paire avec la tradition – notamment, d’un peu de swing et de beaucoup de champagne pendant la désormais légendaire soirée du mercredi soir.

Bien sûr, avec Mumm mis ainsi en avant sur le stand, les discussions ont tourné autour des nombreuses opportunités pour OENODIA chez les producteurs de vins effervescents.

Les récents succès des technologies Stars® en Allemagne, Californie et au Royaume-Uni viennent en effet s’ajouter à une clientèle déjà conquise dans les régions du Cava en Espagne ou chez les producteurs de Prosecco en Italie. Ce succès repose sur les avantages indéniables de cette technologie pour la stabilisation de vins de base : c’est la seule méthode qui peut stabiliser vis-à-vis des précipitations tartrique à la fois potassiques et calciques ; elle supprime les problèmes de gerbage au dégorgement ; elle garantit une stabilité tartrique de 6 jours à -4°C ; elle offre une réactivité inégalée en tant que procédé en continu.


En cette fin à la fois de saison des salons professionnels et de l’année 2019, levons donc nos verres aux réussites passées et aux projets à venir !

TecnoEquip & Oenodia reciben sus embajadores españoles en Provence

La convención ibérica se enfocó en las oportunidades de la tecnología STARS® para la estabilización tartárica en España.


2019 fue una vendimia complicada y heterogenia en España. Un verano tórrido, incendios al oeste de Madrid, lluvias fuertes en septiembre en varias partes del país… Pero la uva se cosechó, las fermentaciones se acabaron y ahora disfrutamos del trabajo hecho y bien hecho. Y a pesar de los bajos volúmenes, la vendimia resultó igual bastante cualitativa.

Oenodia y su socio español TecnoEquip aprovecharon el final de esta temporada para invitar los embajadores regionales de la tecnología STARS en su sede en Provence. En la agenda: visita de los talleres, charlas técnicas alrededor de la estabilización tartárica, visita de Château Coussin (una referencia en Provence) y no hace falta comentarlo, ¡catas!


Una gran mesa redonda permitió compartir los últimos éxitos en España como en Portugal, pero también en Australia y en los EE.UU. Y efectivamente, más allá de sus 25 años al servicio de las bodegas, STARS está presente en todos los continentes y sobre todos los tipos de vino para garantizar la ausencia de cristales y así asegurar los mercados de exportación. Varias bodegas españolas ya llevan años aprovechando la tecnología, en particular en Cataluña. Varias más están a punto de dar el salto, entre problemáticas asociadas de pH, de calcio, en un contexto de competición internacional siempre más exigente.

De Galicia hasta Andalucía, de Aragón y Rioja hasta la Extremadura, pasando por Castilla-León, la presencia regional es una excelente oportunidad para tener esas soluciones a alcance de mano. Una nueva herramienta para que nuestras bodegas puedan aprovechar las tecnologías que mejoren su competitividad.


Como dice Pere Canals, fundador y director de TecnoEquip, “el sector vinícola español tiene una realidad diversa, rica y singular. La flexibilidad de la tecnología STARS® abre en consecuencia muchas oportunidades”. ¡Seguimos confiando que el futuro le dé la razón!

You’ve got the juice: we’ve got the Stars® to make it stable.

Our Stars® technology can stabilize grape juice as well as wine. Let’s zoom in on how one of our US customers gets his juice flowing from the berry to the bottle.

Healthier than sodas and just as refreshing, fruit juices are on the rise. Within the global beverage industry, the fruit juice segment is one of the fastest growing with an expected 6% annual growth rate between 2018 and 2025[1] – and grape juice is not sitting on the sidelines. With a wholesome, natural image and mounting evidence regarding health benefits[2], grape juice consumption is on the rise.

However, despite substantial growth (and an expected + 2% annually until 2023[3]), the grape juice market is tough. Global competition, unpredictable harvest variations and growing expectations from industrial buyers and customers alike mean that each producer is seeking to grow and maintain its competitive edge. For one of our US-based customers, this means developing the high-end segment of NFC (not from concentrate) juice and making sure the product arrives and remains picture-perfect, aka tartrate crystal-free, on the shelves of USA’s biggest retailers.


How does the Stars® technology fit in our customer’s grape juice production process? The fresh, ripe grapes are harvested and taken to the production plant. They are then cleaned, sorted and crushed before being pressed. The juice undergoes clarification, after which it is Stars®-stabilized.

What drew our customer to the Stars® technology? Compared to cold stabilization, Stars® is first of all incredibly more reliable – knowing that cold stab hardly allows to reach required stability levels. Moreover, Stars® saves time, energy and money. Notably, the cut in juice loss drastically slashes costs.  Gone as well the costs of the time-eating, energy-greedy, cold-holding step. Last but not least, the Stars® technology’s unrivalled reliability ensures no product return due to tartrate issues – quite an asset in a fiercely competitive market.





Champagne ! La technologie Stars® intègre une grande maison

A l’occasion de la Grande Matinale de l’œnologie des Champagnes Mumm et Perrier-Jouët, Mumm a présenté la dernière innovation ayant intégré la maison : la technologie Stars®, à travers une ligne couplée de filtration tangentielle et de stabilisation tartrique. L’excellent article de la journaliste et blogueuse champenoise Sophie Claeys relate l’événement qui met également en lumière l’identité de la maison Perrier-Jouët et l’implication du groupe pour la viticulture durable : retrouvez-le ici.

OENODIA’s Revolutionary STARS Technology recognized by top Champagne brand

STARS Technology offers more than just stabilization to Sparkling Wine Producers – helps with disgorging, adjusting pH and lowering calcium!

OENODIA, the oenology division of Eurodia Industrie SAS, one of the world’s leading specialists of membrane-based treatments for the global agri-food industry, has been providing the breakthrough STARS technology for wine producers for the last 20 years.

STARS technology is not only well suited for red or white wines, but it also presents huge benefits for sparkling wines too which is why it has long been used by many sparkling wine producers worldwide. Such countries as Italy for Prosecco or Spain for CAVA and in the U.S. too, several top sparkling brands have been processing their wines with STARS technology for many years.

The trend towards growth looks set to continue with the first OENODIA STARS XF being commissioned in Champagne, at MUMM’s historic facility in Reims, France, this month.

STARS stands for Selective Tartrate Removal System. It refers to a membrane-based process, unique to OENODIA, that offers winemakers a controlled and measured extraction of potassium, calcium and tartrates from the wine prior to bottling.

Winemakers have long lauded the OENODIA STARS technology for providing 100% guaranteed stability, with zero wine loss, measurable energy savings and without the addition of additives, while ensuring the complete removal of the tartrate crystals that many consumers find objectionable in the finished wine.

Furthermore, in addition to these benefits, STARS technology can play a vital role in the sparkling wine process, as it enables you to lower overall pH and to effectively remove calcium. Indeed, calcium can cause headaches for winemakers long after the wine leaves production.

“Calcium crystallization is a new and growing issue worldwide, with no clear scientific explanation so far,” explains OENODIA’s Sales Manager Fabien Requillard. “It’s particularly important for sparkling wine. Calcium doesn’t respond to chilling. It may appear in the wine aging on lees, promoting extra gushing while disgorging and leading to additional wine losses. Some wineries have also seen problems with late calcium crystallization on supermarket shelves years afterward, a crippling non-quality that had never reached the final consumer beforehand. STARS technology then turns out to be essential to prevent such hazards on the marketplace.”

Requillard notes that the beauty of STARS is a guaranteed reduction of calcium concentration, while simultaneously removing tartrates and potassium from the wine solution regarding standard potassium crystallization.

He points out that the Mumm facility in France first implemented a STARS mobile service to confront the calcium issue on a trial basis. Among the reduction in wine loss from 1.5% to zero compared to chilling, they also realized another 1.5% wine savings by cutting down gushing while disgorging. Following the successful trials that were done over the past 3 years, Mumm management decided to invest in a STARS XF unit, the unique in-line combination between a STARS Stab unit and a crossflow filter to streamline their process.

“Producers are realizing that with STARS, they reduce or eliminate wine loss and see a huge saving in energy costs,” Requillard affirms. “Chilling, which is the most common alternative to our membrane-based technology, uses up to 90 percent more energy in the process. Energy and water savings mean money saving.”

OENODIA is the exclusive developer of the STARS Line which features three cutting edge technologies that have revolutionized the global wine industry: STARS STAB, STARS pH and STARS XF.

STARS STAB guarantees immediate and permanent tartrate stabilization via Electrodialysis (ED) with no additives and no adverse effects on sensory characteristics; STARS pH uses the innovative, membrane-based technology to allow you to dial in your pH, to adjust the pH in your wine and must naturally and with precision; STARS XF merges crossflow filtration with STARS to allow continuous filtration and stabilization of wine with no intermediate tank or multiple control function requirements, which facilitates rapid, automated processing.
