Cold Brew Tea: Steeping in the Fridge, Not the Kettle

Cold brew skips the kettle entirely. Tea and cold, filtered water go into the fridge together and sit — anywhere from 12 to 48 hours depending on the leaf — pulling out sweetness and body without ever touching the compounds that make hot-brewed tea turn bitter or astringent. What comes out is cleaner, softer, and quietly stronger than you'd expect.

Ratios and time, by tea: Yabao white tea — 5g per liter, 24 hours. Tie Guan Yin — 4g per liter, 12–24 hours. Dark Oolong — 6g per liter, 12–24 hours. Sheng PUERH — 5g per liter, 12–48 hours. GABA tea — 5g per liter, 24 hours. Red tea — 4g per liter, 12 hours.

How we do it: tea into cold, filtered water, in the ratio above, straight into the fridge. Once the time's up, strain and drink. One rule that actually matters — cover the jar. Skip the lid and you'll get cold brew with a side of whatever else is in your fridge.

Case study: 2002 Xiaguan sheng. 5g of this aged cake to a liter of water, 3 hours at room temperature, then 24 hours in the fridge. The result is deep, dense, and — for an old sheng — surprisingly refreshing: pine, dry hay, a light sweetness, and an aromatic hit that lingers long and cooling after the last sip.

Case study: aged Menghai shu. This one surprised us. 8–10g of well-aged shu to a liter of cold water, 2–3 hours at room temperature, then 12–24 hours in the fridge. What comes out is deep, soft, and remarkably even — woodiness, sweetness, dates, a light edge of chocolate, with none of the heavy earthiness or weight shu can carry. Honestly better than we expected; we're still deciding what to blend it with next.

Want to push it further? A few ice cubes, a spoon of honey, or a handful of fresh herbs all work as extras once the tea itself is done — cold brew is forgiving that way. Filtered water and an actual fridge, not just a cool room, are the two things worth not skipping.
