I should add that if I fill a pint glass halfway with foam and dump it, The next pour is perfect. But, 10 minutes later when that pint is finished, the foam is back. I can do the same thing, and I will get a good pour. But it seems to me I am wasting beer. I am assuming this is happening mainly because the tower is not cooled and the gas separates as the beer warms.
When I have just let the beer sit until the foam goes down, the beer is flat. I am assuming that the flatness is due to the fact that the carbonation was all in that foam. So, I am guessing the best solution is to dump the foam instead of waiting for it to die down?
