Review of WLP090 Super San Diego Yeast
Posted: Wed Jan 04, 2012 8:36 am
I have been working with 090 for a few batches now and I am very pleased. Let it be said that it is a very clean clean yeast in the same vein as 001. The advantage to it is speed and floc time. On the homebrew side, if you have the time, feel free to stick with 001. If you need to shave a few days off your process, give 090 a shot.
It starts pretty fast, under 12 hour if I let the starter go for 24 or so hours. It attenuates well. I mashed my helles type beer (no crystal malt) @156 and got 77% attenuation with 090, with the majority of fermentation happening at 60. It does generate more heat than a 001 fermentation, so keep an eye on your temps. I got 70% attenuation when I mashed at 159 for my Irish Red (15% of grist crystal malt). I have a cal common on now @ 63 and I will report back on that beer when it finishes. That was mashed at 155.
I find that it flocs out 33-50% than 001.
One day on gelatin in 30 degree finished beer, it gets bright.
