I recently ordered 2 6-ers of bell's, Amer and Two-Hearted, since they're fantastic and you can't get them here in NY. I want to harvest the yeast, but i'd also like to enjoy the beers 1-2 at a time. Can I just sanitize a mason jar, pour out the dregs 1-2 beers at a time, and once I have 6-7 beers worth, pitch them into a weak starter? I figure the co2 released by the dregs (with maybe 1/2 oz of beer each time) will blanket the mixture in the mason jar and it should be fine. Will that work?
