Beet kvass is one of those ancient fermented tonics that feels almost magical once you understand how simple it actually is to make. Raw beets are naturally rich in betalains — the pigments responsible for that stunning ruby color — and pairing them with fresh ginger and apple cider vinegar creates a drink that's deeply earthy, gently tangy, and genuinely satisfying to sip. The lacto-fermentation process that happens over two to three days at room temperature is what sets this apart from a plain beet juice: it builds complexity and produces beneficial compounds that make this tonic a smart choice for anyone focused on reducing inflammation through everyday food habits. Ginger is a standout here, bringing its own well-known warming, anti-inflammatory properties to every small glass. The thyme is optional but worth adding if you have it — it lends a subtle herbal note that rounds out the earthiness beautifully. Because you're working with just a handful of whole, unprocessed ingredients and filtered water, there's nothing hidden or inflammatory lurking in the mix. Serve it chilled in small pours and think of it less like a beverage and more like a daily ritual your body will actually thank you for.

Place the cubed beets into a clean 1-quart wide-mouth glass jar. Add the sea salt, apple cider vinegar, and grated ginger. Tuck in the thyme sprigs, if using.
Pour the filtered water over the beets, leaving at least 1 inch of headspace at the top of the jar. The beets should be fully submerged; press them down gently if any float above the waterline.
