So most of you have found that recipes scale linearly except for the boil off rate? During the below zero days of January and February, when I didn't have the willingness to freeze my butt off brewing AG in the garage, I tried James Spencer's 15 minute boil extract method in the kitchen (Basic Brewing Radio). When I linearly scaled down some recipes that I wanted to try from Jamil's Brewing Classic Styles I found that the color was too light in the darker beers. My brown ales were amber and my stouts were brown. Yes, I'm sure I double checked my math for steeping grain additions. I had to doctor the finished beers up with Sinamar to get the right color. So, I'm just curious if anyone else has noticed that they need proportionally more dark grains in smaller batches?
