I have problem with our package product in the summer, winter is good can get 4 mnth shelf life but in the summer it goes off pretty damn quick, not refermenting in the bottle, just tastes musty and all the hop character has gone.
is there any way to combat this problem?
I suspect it to be oxidation, but dont know how to fix it, any suggestion will be much appretiated.
ps things about the beer:
natural co2 from ferment caught at about 1.020 s.g.
D.E. filtered under pressure 120KPA.
Bottled in brown twist top 330ml bottles, purged with co2 then filled buy h&K 25 head filler (counter pressure).
pasturised at 60c for 10mins.
stored in dark place at about 15c.
Winter here is abuot 10-15c & summer is between 30-45c.
