Natural Innovation for the Beverage Industry

For thousands of years, oak barrels have been used to store and mature wine, beer, and spirits — enhancing flavour, colour, and shelf life. At Stoak, we’ve taken this ancient wisdom and transformed it into a modern, scalable solution for beverage producers worldwide.

We extract powerful, natural compounds from oak — no additives, no chemicals — and deliver them in liquid form to preserve, mature, and elevate beverages at every stage of production.

What we do

Mais sustentável, mais econômico, mais eficiente - nossas três ofertas

We extract oak’s natural antioxidants to extend shelf life, slow oxidation, and preserve the fresh taste, colour, and aroma of your beverage — without altering its flavour.

  • Escudo de cerveja is designed for beer, helping brewers maintain hop character, freshness, and aroma for longer — even in packaged or exported formats.

  • Organo Shield is formulated for natural drinks like kombucha, cold brew coffees, iced teas providing a clean-label antioxidant to extend shelf life naturally.

Sourced from 150-year-old French oak and 90-year-old American oak, our extracts help spirit producers meet growing demand – without the high cost or delays of traditional barrel ageing.

  • WLT 150, a natural maturation agent, delivers the flavour, aroma, colour, and smoothness of new-barrel ageing — fast and consistently.

  • Madeva, our barrel rejuvenation product, breathes new life into used barrels by replenishing key oak compounds, reducing the need for frequent barrel replacement.

For wine producers looking to meet today’s demand for clean-label, high-quality wines, we offer two natural solutions that enhance both product quality e shelf life.

  • Estruturano is our range of finishing tannins and structuring agents, used to enhance mouthfeel, stability, colour, and overall wine balance.

  • Wine Shield is a conservante natural that extends shelf life and freshness in conventional, no-sulphite-added (NSA), and organic wines — without altering flavour or aroma.
