Our newest bioengineered strain:

X-Tropica™ Bioengineered Yeast Strain

X-Tropica™

X-TropicaTM is a new and innovative bioengineered yeast from BSI, specially designed to enhance and amplify tropical flavor profiles during fermentation. Using A-56 Chico as the modified base strain, X-TropicaTM has been genetically refined to utilize precursors present in malt and hops to significantly boost tropical flavors like passion fruit, black currant, grapefruit, and guava to as much as 2.5 times the levels found in the base strain. The result is an intensely tropical flavor profile using only the malt and hops already present in most beers — negating the need for excessive hop loads or fruit additions. This technology can help improve beer yields and reduce ingredient costs without modifying your brewing process or extending tank residency times for long dry-hops.

X-TropicaTM has been shown to significantly increase flavor-active compounds:

  • 4MMP – Black currant
  • 3MH – Grapefruit, guava
  • 3MHA – Passion fruit, guava

Usage and Recipe Considerations

X-TropicaTM performs similarly to the base strain A-56 Chico and can be serially harvested and repitched while retaining its tropical flavor boosting characteristics. Certain recipe considerations can be made to optimize the effects:

Malt – Pilsner malt, oats, and dextrin malts can provide added precursors and mouthfeel. Avoid wheat and rye malt.

Hops – Cascade, Motueka, Saaz, Alora

One of our most popular strains right now:

A-72 American Microbrewery Ale

Sourced from a famous brewery in San Fransisco. This versatile ale yeast produces a soft, clean, slightly nutty profile. It finishes with a slight tartness and is fruitier and more flocculant than A-56 Chico Ale. An excellent choice for American pale ale and hazy IPA.

This strain is part of our Express Yeast line and is available for next day shipment!
