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.

Flocculation: variable
Attenuation: 80%
Temperature Range: 65-85F 18-30C
Alcohol Tolerance: ABV 11%

For best results we always recommend ordering an ice pack with your liquid yeast.

Please Note: When choosing an ice pack option beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.

does anyone reuse the yeast cake? sounds like the company does not want you do that according to the package
Tom H on May 15, 2019
BEST ANSWER: Hi Tom - As a homebrewer you have the right to experiment as much or as little as you want. Take a look at this thread - https://www.homebrewtalk.com/forum/threads/saving-yeast-cake.473/

Flanders Red
Excellent blend and very robust. It came warm during the summer delivery - I should have upgraded the ice packs. Pitched this directly into two separate one gallon batches with some oak cubes and still had half leftover. Currently fermenting and smelling great, but need to wait a few months to really tell.

My "Go to" Sour blend
I love the jolly rancher-ish smell this gives off. After primary fermentation completes with something like US-05, I rack into a stainless steel keg and add Roeselare blend. I let it sit at room temp (65-70-ish degrees f) for about 8 months to a year, tasting it occasionally to determine at what point to tap it.

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."
