The brewer riffed on the topic a little on their blog. Very few specifics though.gnutz2 wrote:...I've allways wonderd how they manage their yeast, specifically with it being a dual strain. How do they keep the right balance? Do they have a lab? Do they acid wash? How many repitches between washing? Do they use the same yeast for all the beers?

Yes, they have a lab. I've read they repitch a certain number of times, but I don't know how many. At that point, the ratio between the two strains will have drifted too far apart from their targets, so they start over with a fresh slurry from their lab, and the cycle repeats.
Theoretically, you could save live yeast from an Adnams mini-keg (not bottle-conditioned beers, they use Nottingham for those), and repitch a couple times in your own Adnam clone batches, but eventually one strain will out-compete the weaker one and the fermentation profile will drift just like at their brewery. Then, you poor sucker, you'll have no choice but to purchase and drink another mini-keg.
