For folks interested in the funky/sour stuff, thought I'd update this thread with some of the newer cultures we're offering:
TYB House Sour Blend
The Yeast Bay House Sour Blend is complex blend developed over three years of isolation work, currently consisting of the following organisms:
4 Belgian/Saison Saccharomyces cerevisiae isolates
18 Brettanomyces sp. isolates
Saccharomyces fermentati
Lactobacillus brevis
Lactobacillus delbreuckii
Lactobacillus plantarum
Lactobacillus sp. ("uncultured Lactobacillus" sequencing result)
Pediococcus damnosus
This culture will produce a dry, acidic, complex beer over time with a complementary profile of lactic acid, pineapple/orange/lemon/floral esters and earthy funk. The Lactobacillus and Pediococcus have been maintained in the presence of moderate IBU (~5-10) with the hope that a slightly more hop-tolerant population will persist. However, as with the Mélange Sour Blend, if you want acidity quickly, we recommend keeping the IBU low (0-5 IBU), starting with a fermentation temperature of 70-72 ºF for the first few days and then raising the temperature to 75-80 ºF to encourage development of sourness (Lactobacillus, Pediococcus). For a slower developing beer that exhibits a rounded balance of funk (Brettanomyces) and sourness we recommend ~5-10 IBU, mashing on the high end, fermenting at 68 ºF and holding at that temperature for an extended period of time.
Brettanomyces bruxellensis Strain TYB261
Isolated from a unique mixed fermentation beer produced in the Midwestern United States, this Brettanomyces isolate exhibits a mild tartness and soft funk with a solid backbone of tropical fruit esters (papaya, guava, pineapple, guinep). It's great primary fermenter, but really shines in secondary fermentation following up a primary fermentation that produces a lot of flavor compounds. This strain is a true flavor modulator, and the more raw material it has to work with the greater the complexity that will be achieved in the finished beer. Sequencing results revealed it's Brettanomyces bruxellensis.
This strain will produce a massive, thick krausen, so be sure to use a blowoff tube or reserve plenty of fermentor headspace!
Amalgamation II
The next installment of our "Brett Super Blend", Amalgamation II is a blend of 5 Brettanomyces isolates: Brettanomyces bruxellensis - Strain TYB184, Brettanomyces bruxellensis - Strain TYB207, Brettanomyces bruxellensis - Strain TYB261, and both Beersel Brettanomyces Blend isolates.
This culture is the coalescence of all of the great qualities of each isolate: The balanced funk of the Beersel isolates and TYB184, the sweet tart character of TYB207, and the tropical bouquet of the combined ester profile of lemon/pineapple/guava/mango/papaya contributed by all the isolates.
Expect beers fermented with this blend to finish crisp, dry, tart and unbelievably fruity with just a touch of funk on the finish. This blend produces noticeable character only 3-4 weeks into fermentation and is well suited for faster turnaround beers. Amalgamation II shines as a primary or secondary fermenter, and is sure to please any brewer of Brettanomyces-driven beers.
If anyone has any questions about these newer funky/sour offerings, I'm happy to answer any questions. Cheers!
