Compare Strains
From fruity, hazy IPAs to big, imperial stouts, beautiful strains are born in our enthusiastic hands. We supply both pro and homebrewers in search of unique yeasts backed by uncommon expertise. Please contact us if you’re looking for a specific strain not on this list. We have many more in our private collection.
Floccs like a rock, makes clear beer in a jiffy.
English Ale I is very responsive to wort fermentability, so you can get a wide range of attenuation depending on your mash temperature and duration. This strain works great in any English beer style you are brewing.
WLP002, WY1968
63–71%
Very High Flocculation
18–22°C (64–72°F)
Medium Alcohol Tolerance
Strawberry Jam, Toasty
Stout and Porter, Strong British Ale, British Bitter
Non-diastatic
Low Biotransformation
Medium Fermentation Rate
Non-phenolic
Reliable and classic English ale strain for all clean styles.
Works great as a house yeast for English and American styles. English Ale II is a very versatile yeast that can be used in many different types of beer, including most American and British styles.
WLP007, WY1098
72–80%
Very High Flocculation
18–22°C (64–72°F)
Medium Alcohol Tolerance
Fruit Jam, Malty
Pale American Ale, American IPA, Stout and Porter
Non-diastatic
Low Biotransformation
Medium Fermentation Rate
Non-phenolic
A brewer's favourite for stable haze and juicy flavours.
Foggy London Ale accentuates tropical fruit notes and produces balanced hoppy beers with minimal hop burn. Works great in NEIPAs as well as English ales.

WY1318, A38 Juice
71–78%
Medium Flocculation
18–23°C (64–73°F)
Medium-High Alcohol Tolerance
Fruit Salad, Citrus
NEIPA, American IPA, British Bitter
Non-diastatic
Medium Biotransformation
Medium Fermentation Rate

Alcohol tolerance can depend on additional criteria like yeast health and nitrogen supply. Low: <8%, Medium: 8-10%, Medium-High: 10-14%, High: 14-16%+
Attenuation values are always dependent on the type of wort brewed and represent an average. Depending on the wort that is produced, the yeast attenuation values may fall outside this range.
Based on production of beta-citronellol from geraniol in a standard wort fermentation (terpene biotransformation). Note that the concept of biotransformation also includes other aroma active compounds such as thiols and esters.
Diastatic yeast strains contain the STA1 gene which lets them break down more carbohydrates than a typical yeast resulting in very dry beers (High). Some strains have a deletion in the gene promoter which weakens this effect (Medium).
Based on attenuation at 48 hours fermentation in a standard wort fermentation.
Flavour descriptions are based on a combination of analytical data (GC-MS) and sensory experiences.
Criteria are based on the ASBC flocculation method. Wort production criteria such as calcium ion concentration and pH can impact actual flocculation performance in fermentation.
Temperature range is a suggestion and not the rule. Some brewers like to ferment with Saison strains hotter than the suggested range and Lagers colder than the suggested range. Feel free to experiment!
Many beer yeasts have mutations in the genes PAD1 and FDC1 that eliminate phenolic aroma production. Most Belgian, Saison and Wild yeasts have this trait intact, lending a distinct spicy character to the beer.
This doesn’t mean you can only use this yeast for these styles. Feel free to experiment!
