Temperature of pressure barrels

[wfr42]

I have a batch in my pb in the shed after a week in the warm that appears to have lost carbonation.

The shed thermometer is reading just under 10°c and when I open the pressure release valve band I get a hiss so there is co2 in the barrel.

I used a co2 capsule to check it had sealed initially (and tightened accordingly).

Is 9°c too cold to serve from a pb? As I'm pretty sure the seals are good.

Why do you think it has lost carbonation?
At lower temperature you can get more CO2 in the beer so the over pressure may be lower but the beer will still be carbonated.

I got a glug from the tap.

So while the co2 is 8n solution there is not enough gas to pour

A month ago I kept mine in the back and was bellow 10° and first few pints were ok then list pressure I tend to serve mine between 12-14° and works fine if you prefer it cold pour until you lose pressure then add a c02 bulb as and when required

I don't think the temp is too low.
It must either be that the beer hadn't finished carbonating before it went to the shed, or you have a slow leak on the PB. Or maybe the pressure release band is releasing at too low a pressure??
How much sugar did you prime with?
I'd be tempted to use another CO2 bulb to check the PB is holding pressure.

I did and no hiss....


May move it inside but don't have a designated spot free at present....
