OUR STRAINS

FT01-BUDDY-web-icon1.png

BUDDY | FT01 (American Ale)

Often playing a supporting role in IPA’s and hop-forward styles, Buddy takes a back seat with its clean fermentation profile and lets it’s mates bask in the limelight. With applications across a range of styles from Pale Ale’s and IPA’s, to American Style Stouts and Barleywines, this versatile and reliable strain is a go-to across the board. Brew with your Buddy; a brewer’s best friend. 

Attenuation: 72-80% | Flocculation: Medium | Alcohol Tolerance: 11% | Temp: 19-22°C
Assumed Origin: Sierra Nevada
Format: 💧Liquid Yeast, ✨Dry Yeast


FT02-VAPE-web-icon.png

VAPE | FT02 (Hazy / English Ale)

Clouds no longer belong solely to the sky. The trendy kid on the block, Vape is our answer to sick-as-hazies. Contributing a restrained but present ester profile and a silky mouthfeel,  Vape clouds-out most when partnered with a high dose of hops and proteins to render the juiciest of NEIPA’s.

Attenuation: 71-75% | Flocculation: Medium | Alcohol Tolerance: 10% | Temp: 19-23°C
Assumed Origin: Boddington’s
Format: 💧Liquid Yeast, ✨Dry Yeast


SPECTRA | FT03 (Hazy / English Ale)

Explore the more delicate of textures and indulge in a spectrum of radiant flavour & aroma. Spectra boasts a more robust attenuation capacity than many of its counterparts, while exhibiting an elegant ester profile and velvety mouthfeel. This prolific strain dances with hops & protein to offer a mesmerising glow in New England IPA’s, while its Old English origins make it a wise choice for amber & dark ales.

Attenuation: 72-85% | Flocculation: Low-Med | Alcohol Tolerance: 10% | Temp: 17-21°C
Assumed Origin: Unknown (London)
Format: 💧Liquid Yeast only


RUDEBOY | FT21 (Hazy / English Ale)

Named by Dale Gould as a salute to the UK Ska music scene, Rudeboy is a go-getter when it comes to bright ales - or fuller sweeter Hazies thanks to the lower attenuation . This boy is highly flocculant and rather clean, with a neutral profile that nudges mild malt and soft fruit aromatics to the forefront. Rudeboy scrubs up well bright in all sorts from ESBs and Milds, Dark & Amber ales, as well as new and old world IPAs, Pale Ales & Hazies. 

Attenuation: 68-72% | Flocculation: High | Alcohol Tolerance: 9% | Temp: 18-22°C
Assumed Origin: Young’s Brewery
Format: 💧Liquid Yeast only


FT30-UNICORN-web-icon.png

UNICORN | FT30 (Witbier - Seasonal)

Majestic, sparkly, and a little bit spicy; Unicorn is our answer for Belgian Wits, Blondes, and new age White IPA’s. This unicorn’s horn is made of phenols, shooting a rainbow of clove, spice, and bubblegum out its fluffy white head. High attenuation results in a dry beer with a perception of tartness. Take the rainbow reins and harness the magic that is the Unicorn.

Attenuation: 72-78% | Flocculation: Low-Med | Alcohol Tolerance: 10% | Temp: 18-24°C
Assumed Origin: Hoegaarden
Format: 💧Liquid Yeast only


FT50-KRISP-web-icon.png

KRISP | FT50 (German Lager)

The strain that says it all without really saying anything, Krisp is our classic old-world lager strain. Clean fermenting and applicable for use in classic lagers and new-age Pilsners alike, Krisp delivers on its promise. 

Attenuation: 73-79% | Flocculation: Medium | Alcohol Tolerance: 10% | Temp: 9-13°C
Assumed Origin: Weinhenstephan
Format: 💧Liquid Yeast only


FT51-VAGABOND-web-icon.png

VAGABOND | FT51 (Czech Pils)

This Vagabond may be a bottom dweller, but it sure cleans up nice. Medium attenuation allows for residual sweetness which can elevate nuanced malt and fruit tones on the nose. A crisp, clean finish allows hops to shine through, artfully poised between the malt and dryness. A perfect strain for NZ & Bohemian Pilsners and Lagers. 

Attenuation: 71-75% | Flocculation: Med-High | Alcohol Tolerance: 9% | Temp: 9-13°C
Assumed Origin: Budêjovický Budvar
Format: 💧Liquid Yeast only


SESH | FT52 (German Lager)

This is SESH, the OG of lager yeast. Hailing from the legendary Weihenstephan lineage, this bottom-fermenting strain is a global go-to for a reason. Sesh thrives at cool temps, sending it with steady fermentation and high attenuation, delivering clean, dry, sessionable beer. Cheeky fruity-floral esters elevate your malt & hops to sparkle in refreshing light body. 

Attenuation: 80-85% | Flocculation: High | Alcohol Tolerance: 10% | Temp: 10-18°C
Assumed Origin: Weinhenstephan
Format: ✨Dry Yeast only


WILDING | FTW1 (NZ Wild Ale)

 It turns out, the Rangitīkei District is a pretty funky place; it's the origin of Wilding, the first-ever commercial brewers yeast isolated from the New Zealand wilderness. This yeast isolate was collected as a wild mixed culture from an air-trap (nano koelschip). Subtle spice from phenols, fruity banana, pear and apple esters, and a dry lager-like finish that is surprisingly clean. Validated by PCR as: Saccharomyces cerevisiae var. diastaticus.

Attenuation: 84-93% | Flocculation: Low-Med | Alcohol Tolerance: 10% | Temp: 17-23°C
Origin: Rangitīkei District, NZ | STA1: Positive | Pitch Rate: 0.5M cells / mL / °P
Format: 💧Liquid Yeast only

YEAST MODE (Fermentation Supplement)

A complex blend of essential yeast nutrients, and free amino nitrogen (FAN). FAN is a great support for yeast population growth and cell vitality, so it's great as a supplement in your beer fermentations - especially for high gravity and high adjunct brews like Hazy IPAs, as well as propagations. Good nutrient supplementation is also understood to support haze retention, as the yeast doesn't have to scavenge from the proteins we want to keep bound in your beer. 

USE: 15gm/hL for standard gravity wort. 25gm/hL for high gravity (>15°P) or propagations.
SIZES: 5kg Mini bucket | 10kg Bucket | 20kg Sack
(Contains Yeast Extract | Imported by Froth Tech.)

WHAT OUR CUSTOMERS SAY:

“After our first enchanting trials with their ale and lager yeasts, it was undeniable: Froth Tech wasn't just a supplier, but a soulmate in our brewing odyssey. Aligning with them wasn't just business savvy; for us it was a no-brainer, weaving our fates together in a harmonious collaboration of passion and purpose.”

Mario Lanz
(Co-Founder + Head Brewer)
Double Vision Brewing

“Froth Tech yeast has been great, and we’re now using Vape as our core strain across a number of different beers in the brewery. We’ve seen great viability with every batch we’ve got in, we just chuck it in the tank and straight away it’s taken off, so it’s great to have that consistency.”
