I've been using Wyeast's London 1028 for over five years in our 7bbl brewhouse and have had outstanding results - usually two-day fermentations with amazing flocculation and resulting clarity. This stuff was so aggressive, I produced 1120 bbls last year with two fermenters and three bright tanks.
Now, however, all has gone awry. I've tried culturing up three different charges (from smack-packs) and had the same result: Decent attenuation, really poor flocculation, leading to under-harvesting and thus underpitching the next batch....vicious cycle. Cloudy, yeasty beers are no fun either.
I've torn down and cleaned or replaced all yeast-handling eqpt in the brewhouse to no avail. I finally broke down and got a pitchable quantity directly from Wyeast and it's doing the exact same thing.
I'm confident it's not anything funky going on in the berwhouse, as I'm using the 1098 "British" yeast concurrently and it's performing beautifully.
I'm tired of banging my head on the wall on this, thought someone might have had a similar experience or be able to provide a bit of wisdom.
Thanks!
