Ok..This is noting more than a SWAG, But I'd say your best bet....IF YOU MUST, would be to add Yeast Nutrient and a lot of yeast energiser. Give it a small batch try and see what happens.
There will surely be SOME viable yeast left, and fermentation will occur. I have NO idea what kind of flavors you'd get, but give it a shot and let us know.
Seriously. I'm here for BEER
It's Not The Size Of Your Rig That Counts....It's How Often You Use It.
