I am new to this forum so hello everyone!!! I have been brewing beer for about 3 years now mostly kits but just recently started building my own recipes with mostly good batches and a few odd batches. I am trying to understand what certain verbiage means like ibu's and alpha. I am flipping through a home brewers catalog and don't understand what a "high alpha" means. Can anyone help me understand a little better the world of home brewing?
