ABOUT US
We’re passionate about all things fermentation.
From Lab to Cellar: Aotearoa's Yeast Specialists
HUMBLE BEGINNINGS
Froth Technologies was founded to bring yeast production to Aotearoa, giving Kiwi brewers access to fresh, local liquid yeast without the long delays and hold-ups of importing. We started out in a shared commercial kitchen, pitching our first strains into tiny tanks for one-off brews.
These days, we’re running New Zealand’s first dedicated yeast lab, supplying craft breweries, homebrewers, distillers and cider makers across NZ and afar.
We grow fresh high-performance yeast strains, brewed for local conditions and backed by science. Whether it's reliable workhorses or funky wildcards, we’ve got the goods to help your beer hit the mark.

OUR IMPACT
Froth Technologies is committed to a future where our biodiversity is increasing, not rapidly disappearing as it is now. Each year we measure the carbon footprint of our business operations for the past 12 months. Our footprint is already quite lean based upon emissions minimising decisions made when setting up our business (like electric heating elements instead of gas-fired). We have elected to offset our remaining carbon footprint by 120% with Ekos , granting us Climate Positive certification. We know we can’t offset our way out of the Climate Crisis, but we want to take responsibility for our unavoidable emissions as part of our business operations.
OUR PROCESS
Our yeast propagation process starts with (just) a few million cells. Pure mother cultures are pulled from our -80°C cryo freezer and streaked on to agar plates. Cultures are hand picked from there and innoculated into sterile liquid growth medium. The yeast propagation is nursed into life (and growth) with precise temperature, nutrient, and agitation controls, and checked daily to monitor vital metrics. The propagation is fed daily with increasing volumes. From a start of only a few million yeast cells, the culture grows to a population of up to 100 trillion cells - enough to ferment over 10,000L of beer!
Purity of cultures is achieved through high levels of sterility and hygiene, and this is monitored with strict quality assurance protocols throughout. From the first streak to the final package, Froth Technologies’ yeast is grown with the utmost care and attention, so you can be confident that nothing but the best goes into your tanks.
OUR PASSION
We’re proud to be an independent, sustainability-focused business, supplying yeast and fermentation products to businesses big and small. Our work has picked up national awards for innovation and is trusted by some of the country’s most awarded breweries.
Whether its’ dry yeast or liquid, custom propagations and yeast banking; Froth Tech is your one-stop-shop to help your fermentations thrive.
