Hop Unlock- Thiol Unlocking IPA Yeast- Fresh Yeast Pouch

Description

Please note pitch sizes are for standard gravity wort. For starting gravity above 1.065 please order double the pouches, for gravity above 1.080 order triple the amount of yeast.

Introducing our innovative thiol-releasing yeast product, a game-changer for brewers seeking to enhance and elevate the aromatic profile of their beers. Hop Unlock has been carefully selected to release desirable thiols during fermentation, resulting in pronounced tropical and fruity flavors that are highly sought after in modern beer styles.

By selecting our thiol-releasing yeast, breweries can unlock a new realm of possibilities in crafting unique and experimental brews.One of the key advantages of using our thiol-releasing yeast is its ability to enhance the beer’s aromatic qualities. Thiols, a class of organic compounds found naturally in hops and malt, contribute to fruity, tropical, and citrus-like aromas that are highly desirable in contemporary beer styles such as New England IPAs, hazy IPAs, and fruity pale ales.

Our yeast strain has been selected to maximize the release of these thiols during fermentation, ensuring that the resulting beer is bursting with captivating aromas. By the use of new products on the market like Phantasm, using techniques such as mash hopping, and using hops high in thiol precursors brewers can fine tune the intensity of thiol release and therefore flavour expression. Our thiol-releasing yeast product opens up a world of aromatic possibilities for breweries. With its ability to enhance and accentuate tropical and fruity flavors, this yeast strain empowers brewers to create beers that stand out in today’s vibrant craft beer market.

IRC7 is a gene associated with the production of Beta-lysase, this enzyme is associated with the release of bound thiols. Bound thiols occur naturally in different quantities in various hop and malts but do not contribute to the flavor of the finished product as they remain bound. If the bound thiols naturally present in wort are released it contributes to a more powerful aroma including notes of mango, guava, passionfruit and white wine notes.

Because of these enzymes this yeast can be used to increase your aroma in beer production.  Alternatively reduce the overall cost of hop usage by reducing the amount of hops used or by switching the hops used to less costly hops varieties.

A variety of method can be used to increase the amount of bound thiols in the wort production process:

1. Mash Hopping- Mash hopping with hop varieties such as cascade or calypso at a rate of 3-4g/L significantly increases the amount of bound thiols in the wort and is highly recommended.
2. Whirlpool additions with hops that have high levels of bound thiols. Apollo, Eureka, Hallertau Hallertauer, Nugget, Hallertau Perle and Idaho 7 are all hop varieties that have been tested to be high in these levels.
3. Dry Hopping with hops that work well with a strain that has high levels of biotransformation including Mosaic, Citra, Idaho 7 and Nelson Sauvion.
4. Including thiol precursors in the fermenting beer, there are a variety of products on the markets such as Phantasm that increase thiol precursor compounds within the fermenting wort add at dry hop or at high krausen for best results.
5. Different base malts contain a high variance of bound thiols within them, we would suggest asking your maltster/wholesaler if they can get data on the level of precursor in their malt products. If they are unsure on how to test for this you can put them in touch with our laboratory department.
