I am making a 1/2 gallon starter tonight for an upcomming IPA. I already smacked the yeast pack and I was planing on brewing the IPA this weekend...however I may need to delay it due to some issues with my other brews (see Krausen thread). If I get the starter going tonight and let it ferment for a few days, then pop it in the fridge...how long will it stay? ALso, should I leave the air-lock on it..or replace it with aluminum foil?
