|-
| 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._diastaticusDiastatic_strains_of_Saccharomyces_cerevisiae|diastatic strain of ''Saccharomyces cerevisiae'']]. 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.

| Funktown Pale Ale || || 78-80 || Medium-Low || 68-74 || Funktown Pale Ale is a blend of our Vermont Ale strain and <span style="text-decoration: line-through;">a unique strain of Brettanomyces that is well suited for primary fermentation</span> 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.
