I have a short shelf life on my packaged product because of disolved oxygen. I pasturise srtaight after bottling, 60c for 10 mins, this doesnt alter the flavour to much but the beer only last for about 2 mnths before you can start tasting the oxygen.
I think that the oxygen is comeing from the filling process, the machine used to be pre--evac but they have taken that side of things away & it only blasts a dose of co2 from the bowl pressure to pressurise the bottle, I dont think it is enough what do you lot rekon about my problem.
thanks.
ps if John hinterdink is reading please contact bintara brewery.
