A festive fizzer?
"Apart from buying this lager based on its credentials I also bought it to have some variety among my three taps, which are usually ales, for the Xmas lunch in-laws. I hooked up the keg, which had been sitting in a fridge at 4 degrees for a few weeks, via my new type A-Type keg coupler that I purchased with the keg. All my taps are set for 12 psi as they run off the same manifold. After going through a non-return valve, the dispensing pressure drops to about 10~11 psi. After I hooked up the new Talos 20L keg I poured half a schooner to flush the StellarSan out of the line and cool down the tap body. I then placed a clean glass under the spout and poured a schooner of 90% foam and 10% flat beer. Try again. Same result. Suspecting an over-carbonated beer I installed a Duotight flow control disconnect and after a few pours, progressively reducing the flow rate, I got to the point where the beer was almost dripping out of the spout, and it was still foam. The foam to beer ratio had improved from 90:10 to 80:20. I've never used these Type-A kegs, so I wasn't sure how to decarbonate it like I've done a couple of times using conventional 19L kegs. The beer is obviously good, even though it's flat after all the foaming. I was keen to find out how it tasted under correct carbonation. So, a few days ago I poured a jug of foam and let it settle, poured a bit more, let it settle and then poured the liquid into a plastic bottle. I then fitted a Duotight carbonation cap and pressurised the bottle to 12psi and gave it a good shake and poured a better tasting beer than what had been coming out of the tap. But I am not going through this rigmarole to finish off the remaining 15L of beer. Is this over-carbonation specific to this beer or this batch? Is it something to do with my set-up? Some advice as to how to decarbonate a Type-A Talos keg of Kaiju Cerveza would be most welcome."
