Clarity-Ferm, made with Brewers Clarex, has a significant impact on the appearance of your finished beer. To determine the significance, White Labs customer service associate John Carroll brewed a 10 gallon batch of American wheat with blackberry extract, and split the batch in two, using Clarity-Ferm in one batch and no enzymes in the second batch. Original gravity was 1.040 and final gravity was 1.010

At the National Homebrewing Conference in Minneapolis in June 2010, John opened the bottles for the first time. One bottle had beer made with Clarity-Ferm (in the picture below, the glass is at left) and one without (right glass). A video of the demonstration is also available (see link above). The beer made with Clarity-Ferm had better head retention, several observers noted. But the main impact is appearance-related. The overall results, to us, are "clear."
