Hey Fellow Brewers, So I am new to the grain brewing and learning my ways slowly but surly. Recently I tried a ESB recipe and it came out with way high alcohol content (Over 8%) and all you could taste was the alcohol so I dumped it and want to try again. The only thing I know that did not come out the way I wanted was the mash temp. I am temp using a insulated water cooler until I decide to buy a good mash ton. I put 200 degree water in the water cooler to warm it up before mashing out then dumped it. I put my spark water in and had it at 175" expecting it to drop 15-20 degrees when I put in the grains and also being I was using a water cooler. I dumped in the grains and mashed out and put lid on. It immediately dropped to 145 degrees in the mash ton and 60 min later it was around 140 degrees. Would the alcohol content raise that much to the point it skunks the beer from the lower mash temp. Any help would be greatly appreciated.
