''A great lactic acid bacterial strain mix that will add a pleasant tangy sourness. This mix includes, RVA 600 is a pure culture of Lactobacillus rhamnosus GG which are is found in many commercial probiotic products and which have been shown in clinical studies to have many beneficial effects. These are homofermentative (only produces lactic acid, no carbon dioxide or ethanol) and are hop-sensitive. For more pronounces souring add before you add your yeast. You can sour to taste then add a yeast strain to outcompete the bacteria. Again, hop sensitive so easy on them…or dry hop the heck out of it! You may also want to experiment with blending sour low hop beer with an ale strain beer. ''<ref>From RVA Yeast Lab's [http://www.rvayeastlabs.com/bacteria.html Website]</ref> ''... the amount of bacteria in our homebrew units should eliminate the use of a starter. Pitching on the warm side will speed up the souring but RVA 600, a pure culture of Lactobacillus rhamnosus GG, the first commercially available probiotic propagated for use in brewing, does just fine at room temp. We had originally developed RVA 600 as a mix but fell in love with the pure strain.''<ref>Discussion on Milk The Funk Facebook group with Malachy McKenna</ref>
