A cooled tower IMHO is nice, but not a must have. On my first draw of the evening, I get a spurt of foam that I toss in the sink. Amounts to maybe a swallow. Where these 1/2 to 3/4 glasses of foam come from is trying to pour beer through that first bit of foam. You just can't pour though foam. Some day I will have time to get my tower cooled, just not yet.
