TROPIC THUNDER Tropical Flavor Enhancer

• Unique amino acid blend activates Ehrlich pathway causing beer and wine yeast to produce tropical flavors
• Contributes complexity to beer styles like Hazys where tropical flavors are desired. Pairs perfectly with CellarScience HAZY Yeast
• Contributes tropical complexity to Sauvignon Blanc and Viognier wines when used in conjunction with CellarScience CITRUS Wine Yeast

Enhance tropical flavors in your beer or wine with CellarScience Tropic Thunder. By changing the amino acid mix you feed your yeast you can influence the final flavors yeast produce. To understand why, we have to first explain the Ehrlich pathway which was discovered over 100 years ago by German Biochemist Felix Ehrlich. Yeast absorbs and breaks down a specific set of amino acids very slowly over the course of fermentation. The yeast cells incorporate the amino group into their cell structure, leaving an alpha-keto acid. This acid is turned into fusel alcohol by the yeast and then returned back out into the wort. This production of fusel alcohols via the breakdown of specific amino acids is called the Ehrlich Pathway.

FOR BEER
Fusel alcohol may scare you as a brewer... we get it, you are trained to avoid these! But certain fusel alcohols actually have a really positive effect on the final beer flavor. The idea behind CellarScience Tropic Thunder is we have selected specific amino acids that when fed to your yeast will result in the production of a small amount of fusel alcohols that contribute to the tropical flavors of mango, pineapple, and coconut. Tropic Thunder nutrient is often used to help create complexity in hazy IPA, but feel free to use it in any style where tropical flavors would be welcome—you are only limited by your imagination!

FOR WINE
Tropic Thunder is perfect for Sauvignon Blanc, Viognier and other select styles where tropical fruit flavors are part of your vision. In addition to selecting a thiol releasing yeast strain such as CellarScience CITRUS, Tropic Thunder can help bring complimentary tropical fusel flavors via the Ehrlich pathway. As a part of the overall mix, along with thiols and terpenes, the complexity of Sauvignon Blanc or Viognier is enhanced. Tropic Thunder can also be used in select Chardonnays or any white wines where tropical mango and pineapple flavors are desired. When added at the rate of 0.6 to 2 grams per gallon, Tropic Thunder contributes 3 to 12 ppm of YAN. When using CellarScience FermFed or FermFed DAP Free nutrient blends to power your fermentation, we recommend adding Tropic Thunder on top of these additions.

USE
For beer or white wine add 0.6 to 2 gram per gallon (0.15 to 0.5 grams per liter) directly into the fermenter at the start of fermentation. Perform bench trials to determine optimal usage or start with a dosage of 1.2 g per gal (0.3 g per liter) and adjust as needed on future batches.
