  • Regular price $12.99

“Wild” saccharomyces yeast strain known to produce a huge citrus fruit ester profile.

Citrus cranks out orange and lemon aromas along with some tropical fruit. Use this strain at high temps for big ester production.

A “wild” saccharomyces strain, it will get a bit funky without the worries of a brettanomyces strain.

Keep an eye on your fermentations, it does like to hit a false terminal and then slowly finish out the rest of fermentation.

This strain tests positive for the STA1 gene via PCR analysis and is therefore considered to be Saccharomyces cerevisiae var. diastaticus

We ship all liquid yeast with an ice pack and insulated bubble envelope. Beware that the liquid yeast will not arrive cold even when shipped together. Ice packs and insulated mailing options are designed to keep the yeast colder for longer during shipment, but they will not ensure that your yeast arrives cold. We will not replace liquid yeast that arrives warm. During warmer months we strongly recommend you choose dry yeast.
