Hi all,
I started using my new mash tun yesterday, brewing a dunkelweissen.
Its a brand new coleman cooler 70qt extreme.
I changed the tap valve , other than that no tweaks.
I used 8lbs grain bill for 12l (3.2 gal) water mash.
I pre heated the tun prior to inserting the mash water and grain. The tun is quite big, easily would do double the quantity.
I hitted 145F and closed the tun.
Put a aluminium foil on top of grain bed.
The temperature then droped consistently , and after 90min it was at 125F. That s 20f in 90 min....
At this time, i checked for conversion, seemed ok so sparged.
Sparge water raised the bed to 145 again.
So...temps are very unstable. Dont know why... my room temp is around 65F.
Any inputs on what to try? Others seem to be having no problems with similar setups...
