Biodiversity hike and 1st general meeting PIWI CH

President Roland Renz
The PIWIs are coming ...

On Tuesday, June 30, 2020, almost 60 people met at the Roland organic wine estate and Karin Lenz on the Iselisberg in Uesslingen. The PIWI CH association, founded in December 19, invited to the first general meeting.

In beautiful summer weather, those present set off on a hike through the vineyards of Uesslingen in the lower Thur Valley (TG). Various stops were made on the way. The enthusiastic organic and PIWI winemaker Roland Lenz (two-time organic winemaker in Switzerland) drew attention to the different vineyards and types of viticulture. In an organic farm, a lot of flowers and herbs, sometimes shrubs, grow between the rows to offer beneficial species a home. FIBL's Bea Steinemann reports on the latest attempts to optimize the seed mix between the rows of vines. The hikers also become aware of the differences between European vines and the newly cultivated PIWI varieties (PIWI stands for fungus-resistant and means “robust in cultivation”, ie little to no spraying against pests and diseases has to be carried out). Of particular interest were the references to missing rows of vines in favor of shrubs, the distance to the next trees or the additional insect hotels, all to promote biodiversity.

Back at the Lenz winery, the hikers were happy about the water break before the actual general meeting began. The PIWI CH association was founded last December as a regional section of the PIWI International umbrella organization. The association's goal is to promote PIWI grape varieties in breeding, cultivation, marketing and enjoyment. The association's activities such as participation in the Agrovina or a planned wine and dine in the well-known Hiltl restaurant in Zurich serve exclusively with PIWI wines with certain new taste experiences. The association also publishes the "PIWI WEIN ZEIT" brochure. The readers are connoisseurs and interested individuals, restaurateurs, traders, winegrowers, breeders and journalists. The first edition of March this year was one of the highlights in President Roland Lenz's activity report for the first half of the year. The meeting was characterized by many votes from the members who participate with commitment in the association.

After the official part, the attendees were able to taste and discuss over 40 different pure PIWI wines. These include various new varieties that only have breeding names, such as VB CAL 1-28 or VB CAL 32-7.

"A new PIWI-star is born" - PIWI-CH was founded

"And there is this moment when you feel that you are in the right place at the right time" ...
(Roland Lenz)Logo-PIWI-CH

Yes, the time to express our enthusiasm for the new robust grape varieties could not be a better one! The PIWIs suddenly focus on the latest topics such as species loss, global warming, the call for more sustainable agriculture, or the search for a long-term solution to the pesticide problem!

And best of all: the wines from these robust varieties have become absolutely socially acceptable!
PIWI wines provide positive wow experiences, especially for younger consumers. And more and more restaurateurs, journalists and curious connoisseurs are discovering the associated new flavors.

Yes, we can make a lasting, positive change to the global wine scene! And the
not only because PIWI's grape production is more compatible with the CO2 and more environmentally friendly.
No, also because enjoying these new creative wines is simply fun and demands more!

With this in mind, our 9th regional group was founded at the beginning of the year: PIWI-CH

Comparison of new varieties - vine cultivation

Article by Martin Ladach, DLR Rheinpfalz in "the German winegrowing 3/20"

Vine breeding - New, robust grape varieties not only save pesticides, but are also an answer to climate change.

Investigated grape varieties:
Sauvignac - Cabernet blanc - Calardis blanc - Muscaris - Satin Noir
Weather history 2019 - maturity course 2019 - yield data 2019 ...

Conclusion: The performance data of the new varieties are convincing. Above all, the stable state of health in the maturity phase is of great advantage. In comparison to the classic grape varieties, putrefaction only becomes a threat much later (two to three weeks), so it can be waited much longer to harvest. All in all a good starting point. It remains exciting to compare the results of the wines that will follow soon and of course to taste them.

Produce residue-free wines with PIWI grape varieties from Valentin Blattner

Valentin Blattner

Valentin Blattner, vine grower, Switzerland Contact:

SATIN NOIR (VB 91-26-29)


The Satin Noir variety comes from 1991 by Valentin Blattner and is a cross between Cabernet Sauvignon and resistance partners. The variety clearly shows the genetic relationship to Cabernet Sauvignon. The thick berry skin of the small, concentrated aromatic and colorful berries with a loose grape structure are typical of the variety. Also in the vinification, the wines are deep red in a ripe, harmonious Cabernet manner with a ripeness that is about 10 days before the classic grape variety.
