I’m still amazed at anyone wanting to drink really cold beer!
The only reason to make beer really cold is to disguise the tast. This may be a requirement for a commercial beer, but never for a HomeBrew. (Lager styles being the obvious exceptions.)
Back in the day, before refrigeration became commonplace in pubs and homes, we had to rely on Pubs maintaining “a good cellar”, which usually meant that the beer was served a few degrees below ambient.
I and many others still prefer this temperature. It is relatively easy to achieve in an unheated garage or garden shed!
Enjoy!
