Orsi Vigneto San Vito - "Posca" Bianca NV (750ml)

A solera white wine from from a producer working with indigenous varieties of Italy. Solera, sorta akin to the system used in Sherry winemaking, but the tanks are kept mostly full to avoid the oxidation levels a Sherry obtains. The grapes are farmed organically, the wine is never filtered. There are both skin contact white wines and those without in the blend and fermentation/aging before being added the solera takes place in a mix of oak, cement, stainless steel and anforas.

From Louis/Dressner:

How do you keep track of the solera?

I don’t keep track. I like to bottle five to 10% of the Posca tank at a time, so that when I refill it, it will only be a marginal retraction/addition. And despite these small amounts, it completely changes the balance. It’s like a mother yeast for bread: every time you refresh it, you are changing it. But that mother yeast is also absorbing the new additions, expressing itself differently. 

So the wine is just aging in its vessel before being added to the tank? 

In fact, I have many different vessels, and this is what makes the Posca wines so interesting to me. I'll give you an example: I just added some 2016 in the Posca Bianco tank. It represented about 5% of the tank, and I decided to use a wine vinified in cement because it was tasting very fresh. It coincided with me feeling the Posca Bianco was feeling a bit tired, and I wanted to liven it up. So I added just 5% new wine, and after a week the tank transformed; it was crisper and sharper.
