Strat: How much would it cost for a electric brew kettle?
Kenneth Ryckeley: Could the spray inlet be swapped for a simple whirlpool recirc as in your 3
vessel system allowing for people to stir to their hearts content? Also I
have concerns for hop utilization in a bag, is there any way to use a fine
enough bag to allow the hops to be free floating?
D Noss: Wouldnt the sprinkler head aerate the wort?
Steven Rogers: why do you need a hop bag? How would free floating hops interfere with the
BrewTaku: One thing I like about this system is the ability to brew indoors but I'm
wondering about all the steam from a 90 minute 6 or 7 gallon boil indoors.
Any concerns or suggestions about excess moisture inside the house?
HighGravityBrew: The 44 and 62 quart version have a rim at the top that prevents the basket
from sitting on the bottom leaving a space to place the heating element.
The 82 quart version has feet on the bottom of the basket lifting it off
BrewTaku: Thanks for the info. Thankfully I have a ceiling fan in my kitchen and I
have been thinking of buying a dehumidifier anyway so I think this should
work for me. I think I'll be ordering soon!!!
Luke Crouch: Questions: Could you do this with EBC II? How do you keep the heating
element from scorching the grains? How do you sparge?
Dene McDonald: My efficiency is usually 79%, no sparge and standard crush from the LHBS.
Don't do anything special, but I do step mash and stir lots.
yambor44: Does the basket just sit on the element or is there something in the pot
Ryan ODonnell: Nice system! I was curious about the spray nozzle on the liquidin. Does it
ever get clogged, or does the bag ever get clogged and suck all the liquid
from under the grainbag?
Matt Chelf: stealth, I do BIAB and my efficiencies are regularly between 75%-80%. One
thing you need to remember is that you need to crush your grains much finer
than your traditional AG crush. Mine is almost flour-like. This will
increase your BIAB efficiency...
HighGravityBrew: Tim, 70% is GREAT for a BIAB. The only suggestion I would have it to
possibly crush the grain twice and squeeze the bag to get all the wort
possible out of it. Those are the most common suggestions that I've seen.
Honestly though, 70% is very good. In fact, getting much more than that
even with a traditional 3-tier system runs the risk of pulling "bad stuff"
from the grains.
itsthedrewshow: I do BIAB all the time, and my efficiencies are never lower than 75%. often
John Tomaszewski: This system seems very similar to the streamlined Braumeister from our
HighGravityBrew: That can be an issue. We turn on the ceiling fans and crack a few windows.
Our first time brewing electric indoors was quite comical. The walls
started to collect water and drip down the wall (we were doing a 10 gallon
batch with 13 gallons boiling. I joked that after a few more batches the
walls would be clean! Opening the windows made a significant difference.
HighGravityBrew: Thanks! We love it. Now we can brew in the store!
tj harlow: I just did my first All Grain BIAB and got 70%. Any tips on getting in the
75 to 80 range?
HighGravityBrew: Sorry it took so long to respond. I wasn't getting notified when someone
tj harlow: Thanks... just see a lot of guys getting close to 80% with BIAB so I was
wondering. appreciate the tip.
Ric West: BIAB doesn't mean lower efficiency. I get 75-80% regularly. With BIAB if
using a Voile bag you can crush the grains much finer than you would with
a traditional 3 vessel system since there is no such thing as a stuck
sparge. Also don't forget to squeeze the grain bag to get every drop of
sweet wort. There's no need to worry about extracting tannins by doing it.
