question about BM volumes

Unread postby redwing_al » Thu Nov 06, 2014 1:25 am

I am leaning toward the 20l system. I'm wondering if when you are done with your brew, do you or can you get more wort than requied to account for trub loss . I really want a full 5 gallons going into my kegs... the BIAB process I use today, I usually brew a little more so that I am getting 5.5G to go into a corny keg.

So, can I get a full 5G with a mid-to high gravity IPA or Stout?

thanks!!

Depends how high gravity you want to be able to get and how much trub you're willing to let into your fermenter from the BM. For a 1.060 beer - it would be no problem to get a full 5gal (22 liters) into your keg. You can still sparge with the BM, so that's how some will add top up water to make sure they get the volume wanted.

Once you start getting higher than 1.065, you might want to think of adding extract or double mashing (https://forum.braumeisters.net/viewtopic.php?f=8&t=138).

Perfect.. I dont mind adding LME if needed and I'd have to learn the proper spare techniques. Thanks for the info. I'm looking for a post-thanksgiving (US) purchase!

Check out these two threads for sparging...
https://forum.braumeisters.net/viewtopic.php?f=8&t=282

And doing no sparge (more like BIAB)...

You can fully submerge the BM malt pipe and still get the mash to run fine.

google tells me that 5 g = 18.9 L
5.5 g = 20.8 L
i believe cornys are 19 L, unless i'm mistaken you're not gonna get 22.5L in there?

anyways these volumes are easily achieved with the BM 20. i regularly turn out 25 L batches of medium gravity beers (mid 1.050's?), and keep DME on hand for big batches of higher beers. even with huge trub and dry hop losses 25 L final volume of wort is going to get you more than a full corny!

Oops! Hit the dry gallon instead of the wet gallon tab on my unit converter!

Yeah, I usually target ~22 liters for post boil, then losses get me to 19+ liters.

As others have said - 5 gallons is no problem.

Usually the problem is having too much.... I have 3 30l Speidel primaries and 3 20l Speidel secondaries - and 5 gallon kegs. I've never been short of 5 gallons - and usually have to scramble to find some bottles and bottling sugar for the extra.

We've recently lowered our batch size to target 23l into the fermentor (with Beersmith) and it seems to be hitting about right.
