Subject: Off taste from autolysis? (Martin Weinberg)
Date: 1988-12-31 02:14:56 GMT

We brewed some pale ale recently which is flawed only in that it has an
aftertaste, or rather, a taste when burped. Otherwise, the pale ale
has the desired taste profile. This strange burp flavor is slightly
medicinal and has occurred in a honey ale as well. However, it is
missing from a recently brewed porter. We have been using dry EDME
yeast and wonder if the taste results from a compound leeching from
autolysing yeast. Any comments or advice on how to rid our brew of
this subtle yet unpleasant contaminant?
