BIAB Water Volume Calculator

well... 10 degrees above IF you were doing BIAB in your kettle. you want the water temp in your cooler to be about 10 above your desired strike temp when adding those 60-65 degree grains. since the cooler isn't preheated you're going to lose temp to the thermal mass of the cooler coming up to temp.

if you have a large enough kettle, I would suggest skipping the cooler. just wrap the kettle in a couple old blankets or a sleeping bag and forget it for 60-90 minutes. if you insist on using a cooler, convert it to a mash tun and do a traditional mash.

Thats the goal but don't have the parts for the mash tun and it's little cold to leave in kettle

lol... cold.. you're in Cali.. Its really not too cold. I've done BIAB in 23F temps. the thermal mass of the water and grains will hold heat and if wrapped in a couple layers of blankets it'll stay warm.. a majority of the conversion will take place in the first 30 minutes.. a temp drop of a couple degrees over a 60-90 minute mash won't make a difference in the final product. this isn't rocket science.. remember people were making beer long before thermometers were invented. I promise that in the end you'll still end up with beer.

Just did a BIAB the weekend before last and it was approximately 30F in the garage. I brought the 6 gallons up to temp, wrapped the kettle snugly in its blanket and went inside for 45 minutes. All total it lost 1.5 degrees which isn't too bad.. This is of course with no wind blowing across the pot to cool things down.

Agreed

Ok this what I did .

Mashed in with 165 strike unhear cooler adds grain closed it up.
Checked temp at 15 mins and stirred temp read 150.
Checked temp at 45 mins and stirred still 150.
At 60 min stirred and squeezed.
Pulled hydro and est 140 f corrected reading 1.051.
So now starting to boil and guess my eff ???

looks like you're on your way to making beer! I have 25 minutes left in my 90 minute mash..since mine is a stout and wanting a full body my target was 156.... knowing my setup, I started at 158 and after 65 minutes it's holding at 156 if it drops to 154 in the next 25 minutes it's not going to hurt a thing.

your beer since it was mashed at 150 the entire time, will be on the thin side body wise. what style are you making?

 

[artyusmc]

California common / anchor steam using white labs 810 lagar.

Everybody do helpful here on hbt. Just when I think I know what I'm doing I get a lesson. Haha

 

[artyusmc]

So I'm doing 90 min boil maybe that will help my eff.

I need to add 60 min hops bye
