Spunding valve experience

<< < (2/3) > >>

Kaiser:
I haven’t used it for primary fermentation, but commonly use it for secondary fermentation to carbonate the beer. My experience is that it works fine.

The literature reports that primary fermentation under pressure reduces esters and higher alcohols which allows for fermentation at a higher temperature. Some breweries do that to speed up fermentation while being able to keep the fermentation clean.

There is a guy over on homebrewtalk.com who swears by primary fermentation under pressure. Here is the main thread: http://www.homebrewtalk.com/f13/closed-system-pressurized-fermentation-technique-44344/

I have an adjustable pressure relief valve that I use for counterpressure transferring kegs. But probably couldn't use it during high kraeusen. When do you start your spunding?

wilypig:
Start it right away. Ferm Cap would be a definite requirement for spunding

How much pressure are you talking about?

Kaiser:
0.5-0.8 bar. I don't know how many Psi this is.
