Foam decays
quickly
Detergent or fat
residues on glass
Wash beer glasses
carefully by hand and
don’t put them into the
dishwasher. Rinse glass
with cold water before
pouring in the beer.
Beer composition
Certain ingredients in
beer promote foam
decay and others inhibit
it. Depending on the
composition of the
respective beer, its foam
is more or less long-
lasting. Sadly, the BISON
has no influence on this.
