Having a great brew day!
Finally got my cooler mash tun tuned in to compensate for heat loss. I pumped the strike water in through the drain valve, believe that is called "underletting", real smooth day! A wee pinch over on gravity, right on with volume. Economical too with only a couple ounces of hops
All up to the Notty now.
Will put some pressure on it once it gets going.
If you look closely the 2L growler that is the blow off receptacle is from Charlotteville, which is where this recipe is from!
