Im trying to make a 10 gallon batch in my 70 qt. tun with SG of 1080. Working with grain/water ratio of 2qt/lb. Grainbill from BeerSmith is 30 lbs of 2-row. Mash at 149 for 60 mins or until iodine is negative. Problem is that BS (and my calcs) indicate I’ll be mashing in w/ 18 gallons of water at 157.
Question:
Are these calculations off?
Is it even possible in my 70 qt tun to get a beer with SG of 1080?
can i mash it calculator says it will take 17.4 gallons with 30 lbs at 2qt/pd.
17 gallons is 68 qt. so your right there at the max. is it one of those coolers with a domed lid? some times they add that space in the advertised volume of the cooler. and your actual use-able mashing space is small than advertised. i would say you could do it even if you have to mash a little thicker.
ive been using a 52 qt cooler for a while need to get a bigger one i max out at around 1.065 for ten gal batches.
