Is this right lagar (BIAB sorta of)

[artyusmc]

Hi

Looking for anyones input on 2nd all grain attemp.

I use a turkey fryor 7.5 pot so i do the BIAB part in a cooler. This will be a 4 gallon batch. My question is the mash is for 75 minutes at 148 with 24 quarts and a six pound grain bill, so thats a quart to a pound ratio, i've ben reading 1.25 to a pound?? What gives? Helpful suggestions appreciated, Grains bought so im stuck with what i got and plan on brewing Sunday. thank you

Notes

 

[terrapinj]

mash ratio is usualy quarts/lb - you are measuring Gallons/lb

a lot of BIAB will use full volume to mash - in that case don't worry about your ratio - in your case here is it 4:1

the common range can be anywhere from 1:1 > 2:1 although 1.25 > 1.5 is pretty common for most homebrewers

English brewers generally use a thicker mash (1:1) where as a lot of German brewers would use a thinner mash (2:1)

With BIAB you don't worry about Ratios. It's a no sparge, (first and only runnings), using all the water you need in the mash tun/boil kettle. If you use less water or start going to significantly less water to grain ratio then you need to worry about rinsing your grains/sparging them.

For my 1.050 beers and my setup/style I need to start out with ~ 11 lbs of grain and 9 gallons of water in my mash tun/boil kettle.

Thanx for replying I'm reading mash 24 quarts (apprx) and I have skittle of 6 pounds so that's practically 1:1 , am I missing something?
