The Frog
goes out.

Cuppings, tastings and guest bars — hosted by the cafés and shops we like. We bring the coffee and the bowls; they bring the room. Nothing to book, just come by and taste what we are roasting before it reaches a bag.

The Fermentation Project — Amsterdam Tasting

One Guatemalan coffee, four fermentations, one very curious frog. We are joining James Hoffmann and Lucia Solis' global tasting — live from the roastery in Amsterdam.

The Fermentation Project takes a single lot from Finca San Miguel Urias in the Antigua Valley, Guatemala, and processes it four ways: a control, a wild ferment, a Lactobacillus ferment and a Saccharomyces yeast ferment. Same farm, same harvest, same roast. Only the microbes change.

We brew all four side by side, taste along with the worldwide livestream on 3 October, and argue politely about which one is the frog's favourite. No experience needed — if you can slurp from a spoon, you can cup.

Kits are limited. Bowls, spoons, water and opinions are provided.

The Fermentation Project — Sofia Tasting

The same four ferments, the same evening, a second table — the Frog hops to Sofia, Bulgaria for The Fermentation Project.

Four cups of the same Guatemalan coffee from Finca San Miguel Urias: control, wild, Lactobacillus and Saccharomyces. One variable, four very different cups.

We taste along with the global livestream from James Hoffmann and Lucia Solis, then compare notes with the Amsterdam table afterwards.

Seats are limited — write to info@flyingfrogcoffee.com to hold one.
