Today I transferred beer from my conical fermenter to kegs for spunding. I transferred using 5-7 psi pressure and got a large amount of foam coming out of my keg gas post. In the past, when I spunded in the fermenter, I used a spunding valve on my keg gas post which led to foam-free transfers. I did not think I would need a spunding valve during the transfer as the beer is not carbonated yet. Obviously, there is a fair amount of carbonation present. Suggestions?
