I converted a 10 gallon circular igloo cooler into a Mash tun and have brewed one batch with it...I'm I was wondering if anyone has any straight forward instructions on how to brew a partial mash with this type of converted mash tun. For me, the biggest issue was getting the temperature in the mash tun up to where I needed it to be. It seemed like it dropped 10 degrees when I transferred the water from the stove into the mash tun. This didn't seem right to me...I would add hotter water to try to compensate, but still didnt seem like I was doing it correctly.
Anyone care to help a brewer out?!
