Hario Cold Brew-karaf

The filter basket sits snug inside, so no stray grounds end up in my glass. I just fill it with water before bed and by morning I've got a smooth, concentrated batch that stays icy in the fridge all day. Perfect for hot afternoons when I don't want to heat up the kitchen.

I was skeptical about cold brew at home, but this bottle is dead simple—just water in, grounds in the filter, and it sits in my fridge overnight. The filter keeps the coffee clean without any grit, and it stays cold for hours even on the patio.

The filter basket keeps the grounds fully submerged, so my brew comes out smooth with zero sludge at the bottom. Even on a scorching afternoon, the bottle stays properly cold through my whole commute.
