Omega Yeast LACTOBACILLUS BLEND

$11.99

SKU# OYL605

Flat Rate Shipping only $7.99 only from Northern Brewer
This blend contains two Lactobacillus species - brevis and plantarum - giving the blend a wide active temperature range. The Lactobacillus plantarum strain was isolated in collaboration with Marz Community Brewing from a starter inoculated with whole malt grains. It sours efficiently at lower temperatures (65F-100F) compared to other Lactobacillus species.


This is an Omega Yeast proprietary blend you will not find from other labs.

We strongly recommend ordering dry yeast in the summer months. We do include complimentary Cold Ice Packs with all liquid yeasts. However, it is difficult to guarantee that the ice packs will survive the trip, given transit times and particularly hot temperatures.

Product Details
This blend contains two Lactobacillus species - brevis and plantarum - giving the blend a wide active temperature range. The Lactobacillus plantarum strain was isolated in collaboration with Marz Community Brewing from a starter inoculated with whole malt grains. It sours efficiently at lower temperatures (65F-100F) compared to other Lactobacillus species.

To use the blend for kettle souring a 5 gallon batch, prepare a 1 liter starter of approximately 1.040 specific gravity and pour contents of pouch into unhopped starter. Incubate 24-48 hours at room temperature to increase cell count. Prepare wort as normal and cool to 75-95F. Pitch Lactobacillus starter into unhopped wort and allow to sour to desired level. Maximum levels of sourness should develop within 48 hours. There is no need to hold the temperatures at the high end of the range for effective souring due to the efficient action of plantarum at lower temperatures.

When desired sourness is achieved, re-boil wort to kill Lactobacillus. Add hops at this time if desired. This blend is extremely hop sensitive. Souring may not occur in worts with 2 or more IBUs. Cool wort and pitch yeast to complete fermentation. This is an Omega Yeast proprietary blend you will not find from other labs.

I received this during a record heat wave. Omega flat out states it is necessary to do a starter for this yeast. I did a 1L starter 3 days before pitching. I kettle soured for 3 days in my garage at temperatures outside ranging from 65F at night to 95F during the day. It did just as advertised. Wonderful sour beer. Also, this will not work if any hops are added prior to adding this lacto blend.

Verify viability and vigor before pitching
Upon arrival the package was cool and had been shipped with an ice pack. Despite these precautions no pH change for the first 24 hours was observed in what was meant to be a kettle soured Berliner Weiss. At the same time as culture was pitched a residual drop of culture was plated out. Some CFU's grew with in a few days, but the count was low. Perhaps with aging some sourness may develop, but product did not meet expectations.

Which Northern Brewer Beer Recipe Kit would you recommend using with this Yeast as a Base for a Sour? Berlinerweisse has always been a popular choice because of its low alcohol content and simple flavor but I was curious what other varieties you would recommend.

BEST ANSWER: A lambic or a gueuze turn out great with this yeast. You can use it to kettle sour and make a flanders red as well. While I suppose you could take a brown or red ale and make one of those, it would be better to find a recipe designed around it, built from the ground up to be a sour.
What are the IBU tolerances of the two strains in this blend? I'd like to pitch into a barrel post boil instead of a kettle sour.

BEST ANSWER: I did a ton of reading a research on this which for me led to doing a pre boil kettle sour. That being said, under 3IBU's is what I read across a bunch of interviews, content, etc for all lactos. I would also build a mega lacto starter to pitch, which if you look up Dr Lambic you'll find a lot of great sites. FWIW my kettle sour is coming out amazing.
