Fermenting watermelon wasn’t something I ever imagined, but once I tasted those crunchy, tangy wedges with rind, I was hooked. What started as a fun experiment quickly became a summer staple that’s both refreshing and packed with gut-loving probiotics. The sweet, juicy flesh combined with the crisp rind creates a texture and flavor combination that surprises and delights with every bite.
Why Ferment Watermelon with Rind? Crunch Meets Tang in Perfect Harmony
Using watermelon wedges with the rind intact gives this ferment a satisfying bite, the rind adds crunch, while the flesh offers vibrant tang. The fermentation relies on filtered water, kosher or sea salt (non-iodized), and just a touch of sugar to fuel the natural bacteria’s growth. This sugar and salt brine fermentation preserves the watermelon beautifully while creating an electrolyte-rich, probiotic watermelon fermentation brine that supports digestion and hydration.
Classic Eastern European Flavors with a Bold Twist

Layered throughout the watermelon wedges are pungent garlic cloves, aromatic dill, and crisp celery stalks, bringing the signature herbaceous notes of traditional fermented vegetables. Optional grape leaf enhances crunch, and chili flakes add a gentle kick for those who crave a little spice.
