I will sometimes culture the yeast from Bell's. You can always drink a couple, or three, bottles and use that larger amount of yeast to get things going. There is an ale on tap now in the basement that the Bell's yeast was used for, and it is yummy good.
Will do this again for the next Two Hearted clone. Did it years ago, but have been using the Chico yeast since there is always plent around.
