"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"

New-varieties-ddw2020
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.

Calardis blanc approved!

As the DLR RNH reports, the grape variety is Calardis Blanc Approved under seed law by the Federal Plant Variety Office since March 25, 2020. This means that this variety is approved for the production of quality wine in all of Rhineland-Palatinate growing areas. There is no longer a need to submit a test application for their cultivation and the planting area is not limited.

The first test was the new breed from the Institute for Vine Breeding Geilweilerhof of the Julius Kühn Institute (JKI) passed in January 2018 when it was granted plant variety protection by the Bundessortenamt. In the second test stage, which now resulted in the entry in the list of varieties, a detailed characterization of the viticultural properties and the quality properties was carried out. The name Calardis is derived from Calardiswilre or Gailhardiswilre, the historical name for the Geilweilerhof.

The white wine variety Calardis Blanc combines various resistances to powdery mildew and downy mildew as well as black rot with excellent cultivation properties. In terms of viticulture, it is uncomplicated with upright growth and good resistance properties. According to the Julius Kühn Institute (JKI), the wine is characterized by a finesse-rich aroma of exotic fruits and a fine, spicy bouquet. Due to its tangy acidity, the variety is also very suitable as a base wine for sparkling wine.

The maturity of the new grape variety is about a week before Riesling. It is therefore classified as a medium-late variety, which suits the winemakers who start harvesting earlier and earlier in times of climate change. In Rhineland-Palatinate, Calardis Blanc has so far been grown on 3.8 hectares (as of 1/2020). -jb-

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

Valentin Blattner

Valentin Blattner, vine grower, Switzerland Contact: valentin@domaine-blattner.ch

SATIN NOIR (VB 91-26-29)

General:

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.
