Flein [flīn] is an elegant aperitif or food companion, a special alc-free alternative to a glass of wine.

The grapes for Flein are grown in steep-sloped vineyards and are cultivated and harvested by hand, especially for the production of our juices.

Gently pressed like champagne and pasteurised using the latest technology, Flein enables variety-typical aromas. Flein comes with a surprising freshness, elegance, and lively acidity.

To be enjoyed pure and chilled in a big wine glass!

Varietal grape juices: a joint & regional project

Flein is refined from best grapes of three winegrowers from the Alpine region, all of them long-time friends. Each winery produces the high-quality juice in its own cellar and only region-typical grape varieties are used. They are bound by jointly defined quality principles, laid down in a charter: the juices from different grape varieties and origins open up new dimensions of taste.


Gross & Gross:
Juice from Sauvignon Blanc

Hellgelb im Glas. Sauvignon Blanc-Würze von Beginn an: taunasses Gras, getrocknete Brennnessel, feine Zitrusfrucht. Am Gaumen eine Komposition aus Kumquat, Johannisbeere und Teeblätter. Elegante Säure und Fruchtschmelz bilden ein langes Finish.


Gross & Gross:
Juice from Gelber Muskateller

Goldgelb im Glas. Klare Fruchtaromen sowie Blütenanklänge bilden ein Bukett, das an Minze, Litschi und Holunderblüten erinnert. Das frische Säurespiel animiert zum Genuss. Lavendel sowie reife Mirabelle gesellen sich dazu. Tänzerisch im langen Nachhall.

Flein Fizz

Gross & Gross:
Flein Fizz - Sparkling Grape Juice

Verführerische Nase nach frischen Trauben, weißen Blüten und Wiesenkräutern. Die feinen Bubbles befördern Zitronenzesten und Brennesselblätter nach oben. Der Mousseux ist sehr fein und verschmilzt mit der Frucht zu purem Trinkvergnügen ohne Alkohol.


Cantina Kurtatsch:
Juice from Sauvignon Blanc

Strahlendes strohgelb im Glas. Stachelbeeren, frische Trauben vereint mit grüner Paprika und Limetten. Am Gaumen angenehmes Zucker-Säure-Spiel. Komplex und trotzdem leichtfüßig.

The producers: Flein is made by friends

Gross & Gross from Südsteiermark presented their first Flein in 2018 as a fine, non-alcoholic alternative to a glass of wine. Other winegrowers have meanwhile joined them, all friends from their student days in Vienna. Harald Cronst recently entered the circle with his Flein from Alto Adige's Cantina Kurtatsch. He will be followed by Sebastian Schmidt from Schmidt am Bodensee...

Flein Charter

Our goal is to preserve the flavours of the berries in the juice.


Flein’s vineyard

We cultivate our vines based on organic principles, do without plant protection from summer onwards, and believe in reducing yield. Choosing the right vineyard plot and harvest time is important when it comes to preserving both freshness and a lively acidity in the juice.

Ernte von Hand


All we do on the vine itself is done by hand – from pruning down to harvest. This requires up to nine contacts per vintage and vine. Handwork is simply a must in the steep-sloped vineyards, and a true quality booster.

Flein Ernte Sauvignon Blanc

Gently pressed

Grapes pressed like Champagne: a low press yield of 55 per cent matches that of Champagne. Thus, any bitter substances or unripe nuances are left behind. Only the best part of the berries is used to ennoble Flein, without any compromise.




High-end pasteurisation

To preserve the varietal-typical aromas, we rely on a new pasteurisation process using lower temperatures. The grape juice is bottled cold, briefly heated and quickly cooled down.

A natural product

Flein is nature in its purest form – no artificial flavours are added. Pasteurisation is the natural way to ensure a decent shelf-life. As heat usually kills aromas, we found a particularly gentle solution. Flein is vegan.

Flein mit Spargel

Balanced sugar and acidity

The lean, elegant grape juice with its beautiful acidity guarantees joyful moments. The nose, taste, and aftertaste of this alc-free experience can be wonderfully celebrated in a social atmosphere.

Flein captures a moment that was usually reserved for the winemaker:

„Flein recalls the juice of Sauvignon Blanc running freshly from the press."

Alois Gross (winemaker and father of Veronika)

Flein: a fine alternative to wine

On the lookout for an alc-free alternative to the much-loved glass of wine I kept asking myself: why can grape juice not taste like the variety it consists of?

From my early childhood days, my parents walked through the vineyards with me, explaining the taste of the berries and their varietal aromas in a playful way. Can this taste be preserved in a grape juice?

Is it possible to produce a varietal grape juice with the same appreciation as for wine and to present and/or celebrate the unfermented juice in the same way?

Flein is our answer.


Veronika Mitteregger

Veronika was the first to come up with the idea. She comes from the Gross winegrowing family and actually initiated the project. Today, Veronika takes care of its further development.
