Welcome to The Fun Guy Kombucha Where wild fermentation meets tropical flavor and a dash of mad science.
Dive into our vibrant world of small-batch, artisanal ferments and hands-on fermentation courses that empower you to craft your own.
Hungry? Don’t miss our plant-powered kitchen project, CoraZana Vegana, serving up bold, nourishing flavors inspired by the jungle.
We are based in the south Caribbean of Costa Rica and specialize in tropical plant-based fermented foods and beverages. Our mission is to nourish mind, body and soul with healthy and delicious culinary creations - while sharing the magic and benefits of fermentation with the community.
Kiersun Jones is a plant biologist and fungi enthusiast who left academia in the US to embrace life in the jungle. There, he developed a deep passion for fermentation and working with exotic, local tropical ingredients. A mad scientist at heart, he is the founder of The Fun Guy Kombucha — which has grown to include a wide range of other fermented creations.
Crysthal Mendez, a trained chef from Venezuela, blends traditional culinary training with intuitive creativity to craft stunning dishes using whatever ingredients are on hand. A transformative idea specialist, she is the founder of CoraZana Vegana - which encompasses the alchemical combining of our ferments and other tropical ingredients into ready-to-enjoy culinary masterpieces.
While we’re always experimenting with fresh ideas, we stay rooted in our core fermentation crafts: Kombucha, Water Kefir, Tempeh, Sauerkraut, Plant-Based Cheeses, and Fermented Hot Sauces. Blending these vibrant ferments with our culinary expertise, we craft bold, flavor-packed experiences that’ll ignite your taste buds. Our creations are available locally in the Puerto Viejo area — find us in person at the Saturday Farmer’s Market!
