Ale, Beer, Stout appreciation

They probably waste more than that getting rid of whatever traces of head there are into the drip tray.

Auto vacs sorts that one out. Although we have a beer engine with a sparkler fitted, without auto vacs,and I measured the wastage on the last barrel (72pint) including the sludge at the bottom of the barrel it was 5 pints. So price per pint eventually worked outat £1.20 and Sooo much nicer than bottled beer.
