I recently purchased a variety of equipment from a nano that was shutting down. Included in the lot were these 7 new Auber SYL-2372 PIDs. They had purchased them to power their fermentation control, but never brought any of it online. These have been sitting in a box since purchased in Sept 2015...
I agree with much that is said here. I buy hops by the pound only and have a Google spreadsheet where I keep prevailing prices for the hops I use across all vendors. When I need hops, I take 15 minutes to update the current prices and put together a bulk buy of any hops I need/want to amortize...
I always buy by the pound. I have a spreadsheet in Google docs where I track current prices for hops I use regularly. I prefer to buy from my LHBS and am willing to pay a little extra to help keep a good guy in business. I find that Farmhouse, Nikobrew, Label Peelers, YV, HopsDirect and Rebel...
I love this yeast and have found it to be voracious at quickly attenuating. I usually bump temps to 72* after a three day ferment to encourage it to finish up. I'm currently on Generation 10 of overbuilding and harvesting with this yeast
This is a great point. It's not easy cleaning a ball valve without disassembling. I circulate PBW through my MT, BK, plate chiller and pump before and after every brewday. I open/close the ball valves while recirculating to try and get them clean. Even so, see what was lurking in the coupler...
What temperature did you repitch at? Best would have been within the normal temp guidelines for your yeast. Then ramp the temp after a few days.
I'd expect some off flavors in this batch, between stressed yeast from the initial under pitch and then repitching at elevated temps. But you never...
I'd:
1. Build a small starter of another smack pack of yeast.
2. Pitch the starter at high krausen after 12-18hrs, or so, at current temps
3. Let that ferment out for 3-5 days, and then
4. Ramp to 72* to allow yeast to clean up after themselves.
At least it seems you've narrowed the issue down to something having to do with your old keg. Now... unfortunately, I have had this problem recently with Torpedo kegs. The liquid out dip tube flange is prone to separating from the dip tube itself, causing air to get into/intermixed with the beer...
Thanks for the help on this one. I ended up degassing the carbonated beer, built a starter of San Diego Super Yeast and fermented in the keg it was supposed to be served from according to the Ale schedule I follow (Brulosophy). I transferred to a freshly sanitized keg last night and force...
