Just wondering if anyone else has done something like this and what your results were...
I had 3 old (like 2011 old) packs of Wyeast in my fridge. West Yorkshire, Ringwood and London 1028.
Instead of throwing them out or starting each one individually, I put all of them together (without the smack pack wort- just the yeast) into a 400ml OG 1.035 starter and put it on a stir plate. This was just yesterday afternoon. If it looks like it has some growth, I'll step it up to a 1.5L starter.
Planning to make a dark mild with this when it looks like there is a decent volume of yeast.
