Harvesting in Half Barrel Keg Brinks (SOP) for the community once all the brinks are filled or the yeast slurry has gotten thin mark the total harvest amount on the fermentor track sheet in the crash data area Grab a yeast brink tag and fill it out completely for each brink that was harvested noting the Date harvested, Beer harvested from + batch #, PFV#, generation, amount of tetra and anti foam, and
Yeast Brinks and Load Cells Versus Metering Pump for 30,60 100 bbl DIY brink We made our own from a 3 bbl jacketed, insulated serving vessel (Tielmann): You'll need a vessel, preferably jacketed and insulated, four load cells (or one per foot of the tank), a totalaizer, a scale display, and some welding and electrical skills
Yeast management - ProBrewer Discussion Board We store our yeast in converted half barrel brinks We usually try to crash pretty hard (around 35F) 1-2 days before collection As of right now we do not do any yeast acid washing or a wash with tetraisohumulone (we have never had any issues whatsoever with Lacto in our brewery so we dont open up the brinks more than we have to)
Corney mod for yeast brink - HOW? - ProBrewer Discussion Board Corney brinks We attempted to use a corney for a brink by removing the inner valve stem on the out post but it would still get plugged fairly often We then had the lid drilled and welded with a 90 deg TC and a down tube Worked well but it ended up being too small of a volume for us and we were also quite nervous about all the nooks and crannies
Degassing Yeast Slurries Samples - ProBrewer Discussion Board We pull our yeast samples from our brinks in to 50mL centrifuge tubes for testing, and depending on the density of the slurry (thicker being more stubborn) even a small bit of residual Co2 can make it very difficult to pull a full sample with the (10uL) micro pipette for dilution So I was wondering if anyone had found an
Yeast Brink Recommendations - ProBrewer Discussion Board Cheap, sanitary, and durable do not often come together Cheap - 20l Nalgene bottles, or cornies, sanitary and durable - keg brinks, best option - propagator vessel Big fan of keg brinks for versatility Use them to push chemicals through the canning line, add fruit to beer, store and pitch yeast, and used to use one as a grant back in the day
What are your yeast brink SOPs? - ProBrewer Discussion Board Sample the brinks for pitching calculation right before using as the pH will rise every day little by little Methylene blue is accurate til about 80-90% of you get 85% viability using methylene blue it may be actually more like 50% alive 50% dead
Back-sweetening w Lactose? - ProBrewer Discussion Board My thoughts were to boil the lactose in as little water as necessary and run off to one of our yeast brinks to allow to cool before pushing into the Brite before transfer My only concern from there is potential DO pickup which would probably be low due to the boiling, but figured we could bubble some CO2 from the bottom through the lactose
Biofine p019 isinglass amount? - ProBrewer Discussion Board We also experimented with mixing via CO2 agitation through the bottom port on one of the brinks, and that worked decently The one caveat is that P19 tends to foam up quite a bit, and is very hygroscopic, so you'll want to prepare for those issues (start mixing slowly to avoid sending dust up in the air)
Anticipating your beers FG, Forced Fermentations SOP for example we may use the harvest stout Wyeast 1272 into brinks, then sample the brinks and keep some yeast in the lab for force fermentation down the road Then we take that 1272 and use it for the porter forced fermentation since the porter also uses 1272 yeast
