| B48 Triple Double || Westmalle <ref name="IOY"></ref> || 74-78 || Medium || 65-77 || The perfect strain for your classic abbey ales. Triple Double produces moderate esters with low to no phenolic characteristics. This strain is tried and true and works perfectly in a production environment. Keep an eye on Triple Double, it likes to sit on top of the wort throughout fermentation which may result in a slow fermentation. Similar to Wyeast 3787 and WLP530 <ref name="IOY"></ref>.
|-
| B64 Napoleon || || 77-83 || Low || 65-78 || This yeast is an insane wort attenuator. Napoleon will destroy the sugars in your saison and farmhouse beers – even the ones in which most brewer’s strains have no interest. When all is said and done, Napoleon produces very dry, crisp beers with nice citrus aromas. Yeast settling times can be long, usually requiring filtration for bright beers. Similar to Wyeast 3711 <ref name="IOY"></ref>. Determined to be a [[Saccharomyces#Saccharomyces_cerevisiae_var._diastaticus|diastatic strain of ''Saccharomyces cerevisiae'' var. ''diastaticus'']] <ref name="preiss_diastaticus" />.
|-
| B45 Gnome || Achouffe <ref name="IOY"></ref> || 72-76 || Medium-High || 65-75 || The Gnome is the yeast for brewing Belgian inspired beers in a hurry. This strain is extremely flocculent and drops out of the beer quickly after fermentation. Gnome produces a nice phenolic character that goes well with hops, as well as with caramel and toffee flavors. Great for Belgian ales that need to be crystal clear without filtration. Similar to Wyeast 3522 <ref name="IOY"></ref>.
| INIS-242 Belgian Wit Devil || || 72-76 || Medium || 62-75 || High alcohol tolerance. Similar to Belgian Wit I but with more phenols and clove. Very top heavy requiring a lot of extra space in the fermenter to prevent pushing all of the yeast out of the blow off tube.
|-
| INIS-251 French Ale || || 68-75 || Med-High || 63-73 || This strain produces a clean beer that complements malt with lower ester production than traditional Belgian strains. Excellent yeast choice for a Biere de Garde and specialty beer. Might be a [[Saccharomyces#Saccharomyces_cerevisiae_var._diastaticus|diastatic strain of ''Saccharomyces cerevisiae'' var.

|-
| INIS-317 English Ale VII || || 65-69 || Medium || 80+ || This strain produces a malty beer that is slightly fruity for lower gravity beers. Very high alcohol tolerance makes this a good yeast choice for beers above 10% ABV. INIS-317 English Ale VII has been identified using polymerase chain reaction (PCR) to contain the glucoamylase gene (STA1), which can be an indicator of a [[Saccharomyces#Saccharomyces_cerevisiae_var._diastaticus|diastatic strain of ''Saccharomyces cerevisiae'' var. ''diastaticus'']]. As such, INIS-317 has the ability to utilize some dextrins which are unfermentable to most species of S. cerevisiae, and thus achieve a very high level of attenuation. However, INIS-317 is not considered a contaminant and will not over attenuate finished beer when a high level of attenuation is expected <ref>[https://inlandislandyeast.com/yeast-library/inis-317-English-Ale-VII/ INIS-317 English Ale VII.

| Wallonian Farmhouse II || || 80-82|| Med-Low || 68-80 || This is a single strain of Saccharomyces cerevisiae isolated from the same source as our Wallonian Farmhouse strain, a well-known brewery hailing from the Walloon region of Belgium. Slightly less attenuative and exhibiting a more restrained phenolic and expressive ester profile than our original Wallonian Farmhouse, this yeast is a great choice for any classic saison style beer in which a balance of fruitiness and rustic farmhouse character is desired. Wallonian Farmhouse II works very well in conjunction with Brettanomyces owing to its robust and complex ester and phenol profile, so well that it has the honor of being the dominant saison strain in our new Saison/Brettanomyces Blend II culture <ref>[http://www.theyeastbay.com/brewers-yeast-products/wallonian-farmhouse-ii WALLONIAN FARMHOUSE II.

| Saison Blend II || || 80-86 || Med || 68-80 || This saison blend is the Saccharomyces portion of our Farmhouse Sour Ale, available to you as a result of popular demand from the commercial brewing crowd. This combination of Saccharomyces strains embodies the balanced fusion of the two foremost saison flavor/aroma characters, fruitiness and earthiness. Each Saccharomyces strain in this blend produces flavor compounds that serve as the yin to the other's yang, and the result is an exceptionally complex yet balanced flavor and aroma profile. One strain will serve to create an ester profile of grapefruit and orange zest, while the other will produce a mild earthiness and spiciness. Close your eyes while drinking a beer fermented with this blend, and you'll feel like you're laying on freshly turned earth in an old citrus grove.

| Dry Belgian Ale || || 85-100 || Med-High || 68-74 || Dry Belgian Ale is single strain of Saccharomyces cerevisiae isolated from a unique golden strong ale. The profile is a complex and balanced mix of apple, pear and light citrus fruit with some mild spicy and peppery notes. The apparent attenuation of this strain ranges anywhere from 85-100%, depending upon the mash profile and the grist composition. For a yeast that's as dry as it is, it creates beers with a surprising amount of balance even without the use of specialty grains or adjuncts. While we haven't completed our own tests in house, this yeast is used at the brewery from which it was isolated to make big beers that are in the neighborhood of 12-16% ABV and sufficiently dry. Use Dry Belgian Ale as a primary fermenter in any big Belgian beer, or to unstick that pesky stuck fermentation.

| Northeastern Abbey || || 77-81 || Med-Low || 68-73 || This yeast was isolated from a beer crafted by a well-known producer of Belgian-style ales in the Northeastern United States. This yeast produces a very mild spiciness and earthy flavor and aroma which is complemented by a subtle but magnificent array of fruity esters, including pear and light citrus fruit. The brewery from which this strain was isolated uses it in a very versatile manner across an array of Belgian styles. We prefer using this yeast for any and all light Belgian beers, including Wit, Belgian Pale and Belgian Blond, in addition to any experimental fruit beers in which a more unique and robust flavor and aroma profile is desired. Expect this yeast to produce a large, thick krausen.

Flavour: sweet nutty caramel, light acidity, honey, apple, brown sugar, strawberry/cherry, dry woody, slightly thin mouthfeel. Has its own odd (but pleasant) character and complexity. Final pH was 3.5, which might indicate a blend with lactic acid bacteria (1g/l aged Fuggles at 60 mins, and 1g/l aged Fuggles at 10 mins). Pitch was 1.0 (M cells / ml / ° P) at 19C and fermentation chamber was set to 21-22C for duration.
