Ryan Carville & his business partner Simon Cooke run Froth Tech in Lowe Hutt, the business supplies yeast to breweries across the country.
Together they've spent the last few years traipsing around out in the wops - climbing trees, collecting berries and swabbing bees, all in the hope of creating a new, distinctly Aotearoa beer flavour.
Thei adventures have paid off, the first beer to use their unique "wild New Zealand yeast", is on sale from this Friday.
