Since November I've been using Whitelabs new San Diego Superyeast and have had excellent results. Mind you it's not the rocket that was claimed originally, but does a similar clean job to Wyeast 1056 and is just the job for American Wheats, Summer Ales etc. It reminds me of that old Pacman strain from a couple of years ago.
I find it ferments out nicely in a week and clears beautifully. I just made an APA for a comp at the end of February As usual it went berserk for about 4 days with krausen right up to the lid, then settled down and after about 4 more days (18°C) I kegged it off as there was no further activity. On kegging it tasted rather sweet and syrupy so I did a hydro reading.... 1020
I hadn't done anything different, full malt bill, around 1050, mashed around 65°C, same old same old.
Anyway it was in the Cornie keg so I gave it a good shaking and next morning on lifting the PRV I got a good hiss. Aha, still fermenting. On arriving home I raised the valve again and got a beer shower
- so I very gently let the gas pressure off, with a bit more foaming happening, and loosened off a post on the keg to allow the gas to leak out and stood the keg in a pail.
It literally hissed at me like an angry cat and the foam suddenly started oozing out and runnning down the side of the keg. This morning it's settled down, I tightened up the post and just give the PRV a tug every few hours and get a bit of a hiss. I'll try a gravity reading tomorrow. Then clean up all the bits and put in the kegerator.
Anyone had a stucky with San Diego? I'm putting it down to poor oxygenation initially, have another batch on the go and I gave it a good thrashing with a slotted spoon on the second day, still going vigorously in the FV.
I should point out it's the first stuck ferm I've ever had, after around 200 brews over 4 years.
