How much loss do you have to trub at the bottom of the fermentor

[xCSx]

Hi - was wondering on average - how much % are you losing in your fermentor?

I brew 3 gallon BIAB, and usually I lose nearly half a gallon by the time I go to bottle due to the trub at the bottom.

Thinking of switching to 5 gallons as it is a similar amount of work, but if I am going to lose 1 gallon to trub then I probably won't be interested.

Thanks

I do 5 gal batches and typically see a half gal lost to trub.

It depends on what I pour in there. If the hot and cold break, hops and all goes in, it's a lot, at least half a gallon. If only wort, maybe only a quart in five gallons.

I get about a half gallon every single time for a 5.5gal batch. You need to take this into account for your priming sugar calculations if you are bottling. This goes for buckets and carboys despite their slight differences in surface area.

If Im tossing pounds of hops into an IPA, its a full gallon though

I put the trub in a jar for further decanting and drink that flat beer...
So maybe a quart lost only...
Except for a batch of mango beer...
Maybe three quarts...

about 1/3 gallon on average

The Simcoe/Amarillo IPA I kegged last night had a solid 1.25 gallons of yeast and (mostly) hop debris! Recipe had 1lb of hops, total. The ball valve on my kettle clogged from all the pellets, so a lot of the hops in the BK got dumped into the fermenter.

6-10% depending on yeast, dry hopping, and grain bill.

I rack 5.25 gallons to the fermentor expecting .25 gallon to be trub. But I do bag the hops and leave .75 gallons of cold break in the kettle. I brew enough beer to fill up two 5 gallon corny kegs doing it this way.

I lose about .5 gallons on average. A super dry hopped iipa I can lose upwards to 1 gallon.

I brew to have 5.5 gal going into the fermenter. I bag my hops in the boil, and also if I dry hop. I have the normal yeast cake, and still do get some hop sediment as well. After cold crashing and using gelatin, I plan to leave .75 gal behind when transferring to the bottling bucket to make sure I don't pick up any of the gunk.

I suck up every ounce of cold break into the fermenter and loose a shot glass or two from the brew kettle.It all settles out to around a 1 inch cake and rack as close as possible to the cake.So maybe a pint total loss.I keg so even if I suck up some of the cake it settles out in keg and lose maybe another pint or two

5.5 gallon batches. I lose 0.5 gallons, packaging 5

Lost Beer and Trub

If you want. Save some trub with its billions of yeast cells and use again

In a three gallon batch I lose about a litre to trub. I have a fine bag and use hop sacks, but otherwise pour everything into the fermenter

 

[Morrey]

In a 5.5G batch, I lose .5G about every time. I use hop bags and strain trub with a paint strainer bag into fermenter. If you are dumping it all in, you may lose a bit more. On the flip side, I am taking lots of my "into fermenter" losses up front.

Gavin...Gorgeous slurry!

I brew 2 gallons in two one gallon carboys and lose about .15-.2 gallons due to trub. If I don't think I'm going to get a lot of blow off I will fill up my carboys with more wort to maximize my production.

I BIAB 5.5 gallons using a hop sock. I left behind 0.33 gallons when I kegged 5ish gallons of a pale ale yesterday.

 

[Singletrack]

Half gallon. 7.75 gal into the fermenter and 7.25 gal out. I lose an extra quart or so on IPAs with massive charges of hot and cold (dry) hops.
