Dumping Yeast/Trub

[wepeeler]

For those of you with the ability to dump yeast/trub from your fermentation vessels, what is your normal protocol? I usually wait until fermentation slows, or almost completes, and then get a first dump. Then again after cool crashing or before dry hopping (If I DH), then another dump right before kegging. Seems to be working for me, but I had a chat with a local pro brewer, and he says they do a first dump on day 3 regardless of what is fermenting. He says he wants a fast fermentation and to get the beer off the yeast/trub as soon as possible. His reasoning was that there is a lot of sediment that can contribute off flavors that he wants out of his tanks asap. He said there is plenty of healthy yeast to finish fermentation and clean up. I'm wondering if this parallels home brewing? Get the floccd yeast and trub out of the tank asap and just leave behind healthy yeast to do its thing.

I've read plenty of information that says yeast autolysis can contribute off flavors, but the consensus is that it takes awhile to happen. I keg most of my beer on day 14, and my longest fermentations are 21 days brew day to keg. Just wondering what everyone else is doing!

I don't even think of it as 'dumping', rather; I Harvest the yeast when it looks like I have a good crop and things are mostly settled, usually 3-5 days.

The pro brewer has huge, tall tanks. There's significant pressure on the yeast cake in the bottom, causing autolysis. That's one of the main reasons to drop it ASAP.

I was going to say that in the OP. I know we stress our yeast way less, as far as physics go. Just wondering if it's advantageous for us to dump early too?

In my small 3 gallon conical, the trub is too loose right after fermentation. I usually have to wait till a few days before bottling before I dump it all. Sometimes the lower layers will be compact enough and I can do a partial dump earlier.

My main use case for dumping yeast is in NEIPAs and other very heavily hopped beers, largely to limit the likelihood of restarting fermentation when doing huge dry hops. I don't bother otherwise.

There is no real reason to do so on the homebrew level but I have done it after fermentation is complete. Mostly just to make sure I am transferring mostly beer and as little trub as possible while kegging.

As someone who ferments and serves from same.keg the concept of yeast dumping, other than to harvest yeast, does not compute
