Hario 冷萃咖啡瓶

The heat-resistant glass is a real plus—I can brew in the morning, pop it in the fridge, and pour straight into a mug without worrying about temperature shock. The silicone top seals tight enough that I’ve even shaken it upside down with no leaks, and cleanup is just a quick rinse.

I was skeptical about cold brew at home, but this bottle's heat-resistant glass and soft silicone top make the whole process feel foolproof—I just steep overnight and pour straight from the fridge. It's become my morning ritual, and cleanup takes seconds.

The glass is sturdy enough for daily fridge life, and that soft silicone top seals tight enough that I can shake it without a mess. Brewed a batch on Sunday and it poured clean and smooth all week.
