Our yeast strains don’t have titanic strength or telekinetic powers, but they do empower brewers in ways that will stretch your imagination for what’s possible. (You can read more about the benefits of our extraordinary yeast here.) Guided by our relationships with brewers and our own passion for beer, we have a range of yeast that have been developed from popular workhorse strains to address some of the most common issues faced by commercial brewers.
This is no ordinary yeast. But is it superpowered? Explore our yeast strains below and find out for yourself. Brewing is believing.

Sunburst
Sunburst strains produce a high concentration of ethyl esters that are responsible for tantalizing notes of golden pineapple with just a touch of lemon-lime. These strains will give your beer tropical complexity and a breezy vibe in a way that only fresh pineapple could match.
Sunburst CHICO
Sunburst Chico will send your taste buds to a hammock swaying on a sun-soaked island in the Pacific. We’ve managed this by creating a strain that produces ethyl esters, fragrant flavor compounds that give your beer a distinctive kick of fresh pineapple. Perfect for tropical West Coast IPAs, pale ales, and tiki-style summer crushers.

Tropics
Tropics strains produce the most active thiol-liberating enzyme known to nature. The enzyme under the hood is a carbon-sulfur-lyase (CSL), which converts flavorless precursor molecules in malt and hops into flavorful free thiols. Once liberated, these thiols smell and taste like guava and passionfruit and have notes that are reminiscent of popular new-school hops.

Diacetyl Free (DF)
Diacetyl Free (DF) strains keep diacetyl low during fermentation and after packaging by producing ALDC inside of the cell. With DF strains, diacetyl rests are shortened, beer is packaged sooner, less forced tests are conducted, and diacetyl won’t show up in packaged beer.

Fresh DF
Fresh DF is a great strain for making a variety of crisp clean lagers including Helles, pilsner, and dark lagers. Diacetyl and sulfur stay low during fermentation so brewers can package beer sooner. This is the perfect yeast for breweries that want to make an array of lagers with a single clean-fermenting strain.

Hazy Chico DF
Hazy Chico DF produces the same clean beer that you expect from Chico Ale yeast, but this strain also produces a very stable haze that is resistant to both biofine and prolinase. If you’re a brewer that can’t risk having a beer drop bright, this strain is made for you.

Galactic
Galactic strains produce both lactic acid and ethanol during fermentation, which enables quick-souring in the fermentor without a kettle-pasteurization step. Without the need for long kettle residences and additional CIP cycles when using bacteria to sour, you save time and money. And because they’ve been tuned to produce the perfect amount of lactic acid, there are no off-flavors typically associated with other souring processes.

Chico Galactic
Chico Galactic has become a mainstay for breweries that want to produce consistently clean sour beers, but don’t have time to waste with the typical kettle-souring process. Lactic acid production has been dialed in so that the finishing pH is ~3.5 (TA 7-9). Fruit additions will further increase acidity.

SuperBloom
Superbloom strains produce the terpenes linalool, geraniol, and citronellol during fermentation. These three terpenes comprise the primary flavor determinants of cascade hops and provide beer with a nice floral and citrus flavor and aroma and no bitterness. Superbloom allows brewers to decrease cold-side hop additions or make a flavorful light-bodied beer without any dry-hopping.

Chico Superbloom
Chico Superbloom is an amazing demonstration of the potential of genetic engineering. This strain produces the three primary flavor determinants of cascade hops, which are the terpenes linalool, geraniol, and citronellol. The net result is not cascade hops, but rather a bouquet of orange blossom, geranium, lime peel, and lemon zest. Perfect for West Coast IPAs and pale ales.
