Our blend of lambic cultures produce beer with a complex, earthy profile and a distinctive pie cherry sourness. Aging up to 18 months is required for a full flavor profile and acidity to develop. Specific proportions of a Belgian style ale strain, a sherry strain, two Brettanomyces strains, a Lactobacillus culture, and a Pediococcus culture produce the desirable flavor components of these beers as they are brewed in West Flanders. Propagation of this culture is not recommended and will result in a change of the proportions of the individual components. This blend will produce a very dry beer due to the super-attenuative nature of the mixed cultures.

Great House Sour Strain
I first brewed with this five years ago, and it has become my house strain for sours. I re-pitch some of the slurry, along with the occasional fresh pack to produce well balanced, complex sour beers.

This seems to be the Lambic blend of choice for hardcore sour fans. I have been using it for about a year and it has not disappointed!

Best sour blend
I have used this blend a few times and the beer always comes out great. Like J and J say, "you could add this to sewer water and it will turn out great."

Great Yeast
This is a classic souring yeast that has produced many fine sours. Highly recommended.

Great sour blend
A blend of 2 Bretts, Lactobacillus, Pediococcus and a few other yeasts for good measure, this has been a workhorse for the sour beers I've produced. Since it has pedio and lacto, you have to make a careful choice of when to use. Your time of pitching will determine how much sourness you will end up with - pitch too soon and the bugs might out compete the yeasts, pitch late and you will wait for a long time for sourness to develop.
