I started my first brew today. I chose to do Northern Brewery's Inn keepers ale. All went well until the "og" reading. It was off by .2. What would cause this? In the kit, it said that the og should be 1.043. At first we thought that maybe we took the reading at too warm of a temp. This assumption was correct. We consulted a temperature conversion table...we were then WAY off.
Help for a noob please.
