Stainless Steel kegs in the sun

[MikeKS]

Could you advise me of the implications of pasteurised kegged beer (stainless steel) being left either in the sun or warm temperatures? Does it start to ferment again and at what temperatures and what kind of time periods? In other words could it develop a higher alcohol content?

[Scott Zuhse]

Normally a pasteurized keg is quite stable in most environments. How long is this left in the sun at warm temperatures. Doubtful if higher alcohol content is a factor.

Thank you Scott. My mistake on the pasteurised note, I meant unpasteurised. Temperatures can be as high as 23 celcius in the shade and if in the sun, up to 33.

Unpasteurised beer will spoil if not kept refrigerated.best at 38 - 40 farenheit beer will freeze at 26 I think 33 c is about 90 farenheit wich over carbonate and spoil
