| WLP585 Belgian Saison III || || 70-74 || Med ||68-75 || Produces beer with a high fruit ester characteristic, as well as some slight tartness. Finishes slightly malty, which balances out the esters. Low levels of clove phenolics. Great yeast choice for a summer Saison that is light and easy-drinking. Seasonal Availability: Jul - Aug.
|-
| WLP590 French Saison Ale || || 73-80 || Med || 69-75 || Unique yeast strain producing farmhouse-style beers with a phenolic “bite” and moderate ester compounds. Producing a cleaner aroma profile than other farmhouse styles, this yeast is versatile and highly attenuating. Seasonal Availability: May - Jun. Determined to be [[Saccharomyces#Saccharomyces_cerevisiae_var_diastaticus|''Saccharomyces cerevisiae'' var ''diastaticus'']] <ref name="preiss_diastaticus" /><ref>[https://www.whitelabs.com/yeast-bank/wlp590-french-saison-ale-yeast White Labs website.

| WLP644 Saccharomyces "Bruxellensis" Trois || || 85%+ || Low || 70-85 || Medium-High alcohol tolerance. This Belgian strain produces a slightly tart beer with delicate characteristics of mango and pineapple. Can also be used to produce effervescence when bottle-conditioning. Formally named Brettanomyces bruxellensis Trois, it was re-classified to be ''Saccharomyces'', and probably ''S. cerevisiae'' <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1100249870003226/ Archive of MTF discussions regarding Trois genetic analysis results.]</ref>. White Labs classifies this as a "wild Saccharomyces" <ref>[http://www.whitelabs.com/sites/default/files/644_Explanation.pdf White Labs 644 Explanation. 04/09/2015. Retrieved 5/2/2015.]</ref>.

It, also, does not produce significant amounts of acetic or lactic acid, even under aerobic conditions <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1215686268459585/?comment_id=1215815188446693&reply_comment_id=1215856578442554&comment_tracking=%7B%22tn%22%3A%22R6%22%7D Conversation with Lance Shaner of Omega Labs on MTF. 01/17/2016.]</ref>. Therefore if acid (lactic or acetic) is found in a Trois beer, contamination would be the cause. <s>Approx. 500 million cells per mL; homebrew vials are approx. 17.5 billion cells at 35 mL <ref name="reddit_brett">[https://www.reddit.com/r/Homebrewing/comments/47qbgb/wlp644_cell_count_and_shelf_life/ Homebrewing Reddit post. 02/26/2016.]</ref>.</s> PurePitch packages now contain the same pitching rate as other ''S. cerevisiae'' White Labs strains (1.5 billion to 3.0 billion cells per mL). One example from their "Yeastman" database for lot # 1035203 (02/19/2017) shows 2.3 billion cells per mL <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1670851126276428/?comment_id=1672129959481878&comment_tracking=%7B%22tn%22%3A%22R0%22%7D Paul Illa.
