I'm considering using yeast (wyeast 1056) that's a year old. I've washed it thoroughly with sanitized water in a sanitized vessel before storing it in a sanitized air tight jar, which has been kept in the refrigerator for over a year (approx. 13-14 months.)
Anyone ever attempt something like this? What is the worst that can reasonably happen: perhaps yeasts that don't ferment, in which case I can simply go out and buy a new 1056 smack pack?
