This fall we're probably doing 8 lugs of Cabernet Sauvignon. We ferment in 4 lug batches, so we'll use Avante (got a LOT of it) and another TBD yeast in the second fermenter. I like the idea of filling a 19 liter carboy from each batch for clearing, and blending whatever is left from each batch. After clearing, save 4 liters each from the reserved wine, and blend the remainder into the main batch. This gives me 4 liters (5 bottles) from each yeast, with the blend going into barrels.
We're probably making 8 lugs of Cabernet Franc as well, so do the same thing. This enables long term testing of the 2 different yeast strains in 2 different grapes.
