QBrew

QBrew is an easy to use recipe calculator that allows you to easily modify and create any type of recipe. The program automatically calculates the gravity, bitterness, and color of a beer based on the ingredients you plug in. The database includes many different styles, grains, hops, and other miscellaneous ingredients.

There is an upgraded database that includes Mr. Beer ingredients and can be found here with simple instructions on how to get yourself set up. Below are 2 QBrew screenshots of the Fallen Friar recipe I inputted. The first screenshot is the exact recipe from Mr. Beer. The second screenshot is the same recipe with an added bag of booster. I added the booster because I wanted to increase the ABV of the beer to 5.8%. Notice the difference in Original Gravity (OG) and Final Gravity (FG) between the recipe with booster and without. The OG and FG are used to calculate the ABV for the beer. You also want to make sure you edit the batch size. Since I am using the Mr. Beer fermenter, I sent the batch size to 2.13 gallons (8.5 quarts). I am going to brew the Fallen Friar recipe with the booster as soon as my Mr. Beer order arrives!
