Secondary fermentation in a polypin

Post by gobuchul » Mon Apr 20, 2020 9:35 am

So I have 2 batches of bitter in polypins, they will be dispensed through my beer engine.

I have primed with brewing sugar and they have started secondary fermentation nicely.

If I don't vent them, will the CO2 be absorbed by the beer or could it burst the polypin?

Previously when using polypins and a beer engine I haven't bothered with priming, so not sure what the best thing to do is?

Should I wait until the secondary stops before drinking?

A burst polypin would be a real mess! What temperature do you have them at?

Perhaps best to let some of the excess pressure out if you can. Are the polypins on their 'backs' with the opening at the top? If they are then just open the caps a little to let a bit of gas out.

If they are fermenting well then the gas will be dissolving in the beer as long as it isn't too warm. The cooler the beer the more gas will dissolve in it.

They are currently at a cool room temperature. Just checked the actual temperature of the beer and it is 16C.

I always store them with the tap on the top and if it starts to resemble a football release some gas. As I tend to use yeasts that settle quickly I can slowly turn the pin a day before connecting to the handpump and still get clear beer.
