Hario Filter-In Bottle for Cold Brew Tea

The Hario Filter-In Bottle is the simplest way to make cold brew tea at home — no fuss, no paper filters, no mess. Just add loose leaf tea, fill with cold water, steep overnight in the fridge, and pour. The built-in mesh filter strains as you serve, so the bottle goes straight from fridge to table.

Made in Japan from Hario's renowned heat-resistant glass with a silicone stopper and polypropylene filter, this 750ml bottle is designed to last. Cold-brew extraction is gentler than hot steeping — it draws out sweet, smooth flavour while leaving bitterness behind. The result is a cleaner, more delicate cup that lets your tea actually shine.

Works beautifully with green teas, white teas, oolongs, and herbals. Pair it with any of our loose leaf teas for the best results.
