Session Beer Series: Ordinary Bitter

I am currently on a big Session Beer swing. I really like the idea of trying to capture all the flavor and mouthfeel of a normal strength beer but with less calories and alcohol (also cheap to brew).
This beer was inspired by my favorite internet Radio Station, The Brewing Network's Jamil Zainasheff. I like to use his recipes as a starting point for the style (since he is the style editor for BYO) and taste my way to any changes. He is very generous in sharing his award winning recipes (found here) and even giving you tips on the brewing process.

I must also explain that I am currently doing 3 gallon batches (explanation in a future post). So if you want to scale the recipe then use ratios (or a brewing program. I use an online tool called Brewtility because it does everything I need, its online, and FREE.
