| Flemish Sour mix (F4) |
|
|
60-72°F |
F4 Flemish sour mix produces a sour with fruity and spicy notes. The pediococcus and lactobacillus create a sharp sour that plays well with crystal malts. Use to create moderately sour Flanders ales, Oud Bruin, and Gueuze.
|
| German Sour Mix (G4) |
|
|
60-68°F |
G4 German sour mix is blended for tartness, a heavy dose of lactobacillus and alt yeast make a perfectly crisp sour ale. Use with sea-salt for a sour Gose, add smoked malt for a traditional Lichtenhainer, or keep it simple with a refreshing Berliner Weisse.

| Belgian Sour mix (B4) |
|
|
62-82°F |
B4 Belgian sour mix provides a light lemon-peppery note reminiscent of Trappist beers. The profile is extended with the addition of pediococcus and lactobacillus. This blend is great for deep farmhouse ales.

68-80 |
A blend of a mild Brettanomyces isolate from a Colorado brewery known for its Brett beers and two strains formerly classified as Brettanomyces but since found to be Saccharomyces (Trois and ECY-03b). This blend produces huge tropical fruit aromas during fermentation that fade somewhat during conditioning. Has a wide temperature range and ferments very dry, leaving little body. Consider adding flaked oats if additional body is desired. This blend will not produce significant “funk” or acid, even with extended aging. The blend pairs well with fruity aroma hops to make a unique pale ale. Homebrew pitches contain ~150 billion cells [5].

The “bit ‘o funkiness” will take extended time (3+ months) to develop. Trois (Sacch), ECY-03b (Sacch), and bruxellensis blend. Homebrew pitches contain ~150 billion cells [5].

Brett character will develop over time. Acid production will increase over time given exposure to oxygen. Trois (Sacch), ECY-03b (Sacch), bruxellensis, claussenii, lambicus, custersianus, and naardenensis blend; funky and fruity given time, acid production increases with exposure to oxygen over time.

A "coast to coast" blend of a saison strain from a famous Northeast U.S. brewery and a Brettanomyces strain from a Northwest U.S. brewery. The blend results in a fast developing fruity and funky farmhouse ale. Homebrew pitches contain ~150 billion cells [5]. Making a starter for this blend is optional, and Lance recommends not worrying about throwing off the ratio of strains. The beer should start off clovey, and gets funky over time. The Sacch strain is predominately clovey at 68-70°F, and can have additional fruity character to compliment the clove above 70°F [6].

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. Approximately 58 billion cells/vial.

Funktown Pale Ale is a blend of our Vermont Ale strain and a unique strain of Brettanomyces that is well suited for primary fermentation Saccharomyces "Bruxellensis" Trois. The combination of the citrus/peach esters from the Vermont Ale strain and the very light funk and pineapple/mango esters from the Brettanomyces produces a unique flavor and aroma profile that is fruit-forward. Expect this blend to finish drier than the Vermont Ale. We recommend following a similar fermentation scheme as is used for the Vermont Ale, fermenting at 67-69 ºF for 3-4 days, and then raising the temperature to 72 ºF until a stable gravity is reached. Approximately 58 billion cells/vial.

This blend includes a German ale strain with low ester formation and a dry, crisp finish. The Lactobacillus included produces moderate levels of acidity. The unique Brettanomyces strain imparts a critical earthy characteristic that is indicative of a true Berliner Weisse. When this blend is used, expect a slow start to fermentation as the yeast and bacteria in the blend is balanced to allow proper acid production. It generally requires 3-6 months of aging to fully develop flavor characteristics. Use this blend with worts containing extremely low hopping rates. Private Collection for Spring 2015 (available April-June 2015).

A blend of Saison yeast and Brettanomyces creates a dry and complex ale. Classic earthy and spicy farmhouse character meets tropical and stone fruit esters; aging brings elevated Brett flavor. Expect high attenuation with this blend. Available from July through September 2015. From Wyeast: "The 3031 blend is a couple different saison strains and a Brett c. The blend should produce a moderate Brett character is a relatively short amount of time (approx. 8-12 weeks), which should increase with age. It will do best at a fermentation temp of 65-80*F, with higher ester formation at the upper end of that range." [12]

Wyeast, as part of their Private Collection series, has come out with their Old Ale Blend. Using both an attenuative strain of Saccharomyces and a strain of Brettanomyces, the two work in tandem to create lovely, classic British-style ales. Working particularly well in darker worts, this blend can create wonderful barleywines, old ales and strong ales. The blend creates ales with a nice fruit character and wonderful esters, and the Brett will work on the beer with time, bringing out pie cherry notes with the tart sourness and horse blanket flavors typical in traditional, well-aged old ales. A great strain to use when producing big beers that will develop deep and complex flavors over time! Private Collection for Winter 2015 (available Oct-Dec 2015). The Brett is rumored to be Wyeast 5526 (Lambicus) and the Sacch is rumored to be the Thomas Hardy yeast [13].

"You can definitely make a starter for the Melange or the Lochristi Blend. For the Lochristi, run it semi-aerobic for 4-6 days in the 70's and then let it settle at room temp and decant what you can if the starter is large. For the Mélange, run the starter semi-aerobic at 66-68 F for 24-36 hours. This should build up the yeast population sufficiently while not allowing the bacteria to become to active and produce a ton of acid." [14]
For The Yeast Bay Farmhouse Sour Ale, a starter is optional. If the brewers is looking for more farmhouse character from the yeast, create a normal starter with yeast nutrients, and use a stir plate. If the brewer wants to stress the yeast and favor the bacteria, do not make a starter. Nick Impellitteri says that he prefers to do a starter so that the yeast has a good, clean fermentation. He then ages the beer and waits for the bacteria to sour it over time [15].
"My yeast blends are 95 billion CFUs of bacteria for primary fermentation [with] 1.055SG/5 Gallon direct pitch." - Barrett Tillman, owner of BMY [16].
