How a Belgian Contract Brewer Went From a Guide Download to Production Supply in Five Months

Samples on the bench in a contract brewery

A Belgian contract brewer makes drinks for other brands. When fermented drinks came onto their radar, the team wanted to understand the options before offering them to clients. Their first step was downloading one of our free guides.

Exploring a New Category for Their Clients

Contract brewers work on many briefs at once. Every new ingredient has to behave the same way across different recipes, and it has to be available at the right scale when a client is ready to produce.

For a brewer new to fermented drinks, that's a lot to prove.

The team needed to test the base themselves, understand the specs and know how bulk supply would work before they could commit.

Small R&D Samples Before Committing

A few days after reading through the guide, the brewer placed a small R&D order. They took Good Culture's Organic Fermented Green Tea Base and a second fermented tea base, so they could compare the two.

Good Culture shared the specs and the Kombucha Producer's Guide to support their trials. Soon after, the brewer came back with questions on bulk formats and lead times, ready to plan for production.

Production Supply Within Five Months

Within a couple of months, the brewer placed its first production order of raw Organic Fermented Green Tea Base. Good Culture sorted the delivery details with the team, and the order shipped later that month.

In just five months, the brewer went from a guide download to production supply. They now have a fermented base in place for their clients' drinks.
