|-
| INIS-298 Saison: Baron || France || 70-80 || Medium || 70-80 || A true Bier-de-Garde yeast from France. Yeast produces a briny flavor and notes of white pepper and straw.
|-
| 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 [[Saccharomyces#Saccharomyces_cerevisiae_var._diastaticus|''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.

| INIS-491 Saison: French || || 77-83 || Low || 65-77 || A saison strain that produces more phenols than the Belgian Saison strains. Notes of pepper and citrus along with other spices. This yeast leaves behind a pleasant mouthfeel in the beer despite being highly attenuative. It is less likely to stall than the Belgian Saison strains. This strain has been identified using polymerase chain reaction (PCR) to contain the glucoamylase gene (STA1), which can be an indicator of [[Saccharomyces#Saccharomyces_cerevisiae_var._diastaticus|''Saccharomyces cerevisiae'' var. ''diastaticus'']]. As such, INIS-491 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-491 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-491-Saison-French/ INIS-491 Saison: French.
