When making wine coolers can you just siphon off you finished product and reuse the same yeast at the bottom? Do you need any yeast nutrient/energizer? If you can, how many times can it be repeated or is once the max?
I have a yeast slurry of Lalvin 71B that I started on a white grape peach wine and is now at the bottom of a clearing skeeter pee wine. I plan to use it again on a mead coming up soon. It should work. However I will still use normal nutrient additions as I would with fresh yeast.
There is a small amount of flavor that carries from recipe to recipe but when dealing with 5 gallons at a time it Is not much. I just use simple cheese cloth to strain out any pulp and then pour in the yeast cake when ready.
