7. Some time ago many licensees followed the brewers' recommendation
of using only clean glasses and refused to refill used beer glasses.
This experiment failed partly because of the objections of many customers

these are designed to deal with any bacterial or salivary contamination of the beer.
They are purely methods for the removal of fines; i.e. yeasts, vegetable matter and grit which may be found in a beer barrel.
