Hybrid Series

SAISONSTEIN’S MONSTER OYL-500

The first in our line of hybrid strains. A genetic hybrid combining the robust fermentation of French Saison (OYL026) with some flavor characteristics of Belgian Saison I (OYL027), this strain exhibits some of the best characteristics of each. Created by and available exclusively from Omega Yeast Labs.

  • Flocculation: Low
  • Attenuation: 80-90% 
  • Temperature Range: 65-78° F
  • Alcohol Tolerance: High

GULO™ ALE OYL-501

Gulo Ale is the latest creation to emerge from the curious minds of Omega Yeast. The progeny of Irish Ale (OYL-005) and French Saison (OYL-026), this true genetic hybrid is a beast at devouring sugars, which creates a very dry beer without any of the peppery, clove phenolics associated with saisons and Belgian ales..

  • Flocculation: Medium
  • Attenuation: 85-90% 
  • Temperature Range: 68-77° F
  • Alcohol Tolerance: 12% ABV

Ales

DIPA ALE OYL-052

Ale strain isolated from a famous double IPA brewed in Vermont.  Produces a unique ester profile reminiscent of peaches.  This strain complements an aggressive use of hops.

  • Flocculation: Medium-Low
  • Attenuation: 72-80%
  • Temperature Range: 65-72° F
  • Alcohol Tolerance: High

WEST COAST ALE I OYL-004

Clean, crisp flavor characteristics with low fruitiness and mild ester production. A very versatile yeast for styles that desire  dominant malt and hop character. A very popular “house” strain May yield citrus notes with cooler 60-66°F fermentations.

  • Flocculation: Medium-Low
  • Attenuation: 73-80%
  • Temperature Range: 60-73° F
  • Alcohol Tolerance: 11% ABV

HOTHEAD ALE OYL-057

An ale strain of Norwegian origin that has an astoundingly wide temperature range (62F-98F) with little difference in flavor profile across the whole range.  Temperature control is unnecessary with this strain.  It has a unique fruitiness that makes it complementary to modern hop varieties.

  • Flocculation: Low-Medium
  • Attenuation: 75-82%
  • Temperature Range: 62-98° F
  • Alcohol Tolerance: 11% ABV

HEFEWEIZEN ALE OYL-021

The most popular German wheat beer strain used worldwide. Produces a balance of banana esters and clove phenolics that can be skewed depending on various conditions - e.g., increased ester production through increasing the fermentation temperature, increasing the wort density, and decreasing the pitch rate or over pitching to reduce or nearly eliminate banana character. Decreasing the ester level will allows higher clove character to be perceived. Sulfur is commonly produced, but will dissipate with conditioning. This strain is very powdery and will remain in suspension for an extended amount of time following attenuation. This is true top cropping yeast and requires fermenter headspace of 33%.

  • Flocculation: Low
  • Attenuation: 73-77%
  • Temperature Range: 64-75° F
  • Alcohol Tolerance: 10% ABV

BANANZA™ ALE OYL-400

Ripe Banana esters, with a hint of pear, makes Omega Yeast's new exclusive strain OYL-400 Bananza™ a stand out for pastry stouts, milkshake IPAs and other modern ales. Unlike its parental Hefeweizen strain, Bananza™ is versatile because it is non-phenolic and therefore incapable of producing clove flavors that would mask its pure banana profile.

  • Flocculation: Low
  • Attenuation: 73-77%
  • Temperature Range: 66-75° F
  • Alcohol Tolerance: 10% ABV

SUNDEW™ ALE OYL-401

Omega Yeast OYL-401 Sundew's ripe strawberry, passion fruit, pear, and stone fruit combine to emphasize desirable notes in modern fruity hops. This Omega Yeast exclusive strain was inspired by its parental strain's fruity esters, which were originally obscured by Belgian phenolic character. Sundew™, however, is non-phenolic and incapable of producing the spicy clove flavors that were previously competing with its pure, juicy red-fruit bouquet.

  • Flocculation: High
  • Attenuation: 72-85%
  • Temperature Range: 65-78° F
  • Alcohol Tolerance: 12% ABV

British Ales

BRITISH ALE I OYL-006

Allows malt and hop character to dominate the profile. Highly  flocculant and highly attenuative. Ferments well down to 64°F.

  • Flocculation: Medium-High
  • Attenuation: 70-80%
  • Temperature Range: 64-72° F

BRITISH ALE OYL-016

A classic ESB strain best suited for English style ales including milds, bitters, porters, and English style stouts. Ales produced with this strain tend to be fruity, increasingly so with higher fermentation temperatures of 70-74°F. A thorough diacetyl rest is recommended after fermentation is complete. This yeast will leave a beer very clear, and will leave some residual sweetness.

  • Flocculation: Very High
  • Attenuation: 67-71%
  • Temperature Range: 64-72° F
  • Alcohol Tolerance: 9% ABV

BRITISH ALE OYL-005

  • Flocculation: Medium
  • Attenuation: 69-75%
  • Temperature Range: 62-72° F
  • Alcohol Tolerance: 12% ABV

Belgian Ales

BELGIAN ALE A OYL-024

Versatile strain for the production of classic Belgian style ales. This strain produces a beautiful balance of delicate fruit esters and subtle spicy notes, with neither one dominating. Unlike many other Belgian style strains, this strain is highly flocculent and results in bright beers.

  • Flocculation: High
  • Attenuation: 72-85%
  • Temperature Range: 65-78° F
  • Alcohol Tolerance: 12% ABV

BELGIAN ALE W OYL-028

Classic strain for brewing Belgian dubbel or Belgian tripel.  This strain produces a nice balance of complex fruity esters  and phenolics, making it desirable for use in other Belgian style ales as well. A flocculent, true top cropping yeast (additional headspace is recommended), that will work over a broad  temperature range. Makes a great Belgian style “house” strain.

  • Flocculation: Medium
  • Attenuation: 74-78%
  • Temperature Range: 64-78F
  • Alcohol Tolerance: 11 to 12% ABV

BELGIAN ALE DK OYL-049

Bacterial Cultures

LACTOBACILLUS BLEND OYL-605

This blend contains three Lactobacillus strains-- brevis,  delbrueckii, 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 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 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.  Cool wort and pitch yeast to complete fermentation.  To use blend for long term souring, pitch contents of pouch directly into wort or finished beer.  Sourness can take 3 or more months to develop.  IBUs should be kept below 10 so as not to inhibit Lactobacillus growth.

  • Flocculation: NA
