First thing, every morning (well, after a cup of coffee!) I take my collection of stuff to the fermenting bins to determine how far along the road to dryness each fermenter is. I draw some wine from under the cap of skins with the siphon (turkey-baster thingy), strain it through the strainer into a beaker. I then use the DMA (a density meter) that records the brix level and temperature of the wine. If we are close to dryness, I’ll bring a sample to the lab to get residual sugar levels that will tell me if that bin is, in fact, dry. This morning one of two Sangiovese bins was.
Of course, I am tasting the samples every day to experience how each wine tastes and feels as flavors and texture jump around a lot at this point in the process. With more than one bin of the same wine, I’ll make ad hoc blends to see how the bins work together, and how they may taste when all fermenters are dry.
