added to TYB cultures: Saison/Brettanomyces Blend II
| Farmhouse Sour Ale || 80-90 || Med || 70-78 || Expect this blend to take 1-3 months to begin creating appreciable levels of acidity. This blend contains two farmhouse/saison ''Saccharomyces cerevisiae'' isolates, ''Lactobacillus brevis'', and ''Lactobacillus delbreuckii''. The two ''Saccharomyces'' strains will combine to create a delightful ester profile of grapefruit and orange zest, accompanied by a mild earthiness and spiciness. The two ''Lactobacillus'' strains will produce a balanced acid profile, given a suitable supply of accessible carbohydrates that remain after the bulk of fermentation has been completed by ''Saccharomyces''. Expect this blend to take 1-3 months to begin creating appreciable levels of acidity, depending primarily upon fermentation temperature and the IBU. Higher fermentation temperatures and lower (0-5) IBU will produce elevated levels of acidity. Lower fermentation temperatures and higher (10+) IBU will produce lower levels of acidity.

| Saison/Brettanomyces Blend || 80+ || Medium-Low || 70-78 || This blend combines one of the ''Saccharomyces'' strains from the Saison Blend and two unique ''Brettanomyces'' isolates from our yeast library. The ''Saccharomyces'' yeast strain is a strong attenuator that produces a delightful ester profile of grapefruit and orange zest and imparts a long, dry and earthy finish to the beer. The ''Brettanomyces'' strains are both good attenuators that produce some fruity esters and mild funk, and add a bright character to the beer. The combination of these yeast produces a dry but balanced character with a delightful ester profile and just the right amount of funk. The two Brett species are both ''bruxellensis'', each isolated from a different Belgian lambic beer <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1286169764744568/?comment_id=1286181778076700&comment_tracking=%7B%22tn%22%3A%22R0%22%7D Conversation with Nick Impellitteri on TYB Saison/Brettanomyces Blend. 04/16/2016.]</ref>. Approximately 58 billion /cells/vial <ref name="tyb"></ref>.|-| Saison/Brettanomyces Blend II || 82-85 || Medium-Low || 72-80 || The cultures in this new and unique blend include two saison-style Saccharomyces cerevisiae isolates (Wallonian Farmhouse II and Wallonian Farmhouse III) and two Brettanomyces bruxellensis cultures (TYB184, TYB207). This blend will produce a beer that is bursting with classic saison character with a rustic kick of Brettanomyces fruitiness and funkiness. While exhibiting a mild hay/barnyard component, the overall character is heavier on the fruit-forward end of the spectrum compared to our original Saison/Brettanomyces Blend. The Brettanomyces portion of the culture tends to generate character rather quickly owing to the nature of the strains used.

| TYP House Sour Blend || 85+ || Med-Low || 68-78 || The Yeast Bay House Sour Blend is complex blend developed over three years of isolation work, currently consisting of the following organisms: 3 Belgian/Saison ''Saccharomyces cerevisiae'' isolates, 16 ''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°F 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.
