I am wondering if anyone has experienced this - I was racking from a low pressure fermenter to a keg using a closed loop set up (Speidel with spunding valve at 2-4 psi at late ferment - 10.5 gallon batch). Fermenter to Keg out post flow direction and keg gas post to top of fermenter gas post). The spigot to keg line was clear tubing, so I could monitor the flow. The first 5 gallons flowed to the keg without incident, but then about midway through the second five gallons, the tubing developed enough CO2 release from solution to become "blocked" for the flow of beer. I lifted the keg up to allow for the CO2 to clear the line, but the same thing developed a bit later. So, it became a very slow racking to the keg. I experienced this once before with a Belgian Tripel that I rushed to finish (for contribution to a club barrel project) and it had not off-gassed. This time it was a Pilsner that I intentionally carbed a bit at the end of fermentation...any thoughts on this situation? I know I won't encounter the issue on the Kegmenter set up that I now also use, but I hate to put other fermenters out to pasture for fear of this recurring. Cheers for any insights or process suggestions.
