Changed oil on motorcycle, installed switched outlet above bar for bar lights, moved phone jack to new location.
When making a high gravity beer (O.G. 1.060 or higher) you need to increase the number of yeast cells by making a yeast starter.
Preparing a yeast starter is easy - you mix a very small batch of malt extract wort (without hops), briefly boil and chill it, then ferment it in a flask a day or two...
