Whether you’re dealing with sweltering temperatures or an irritable stomach, if you’re anything like us, your daily coffee intake comes from cold brew. There are plenty of great cold brew coffee makers, options to make coffee shop cold brew at home–and even our guide on How to Make Cold Brew Coffee–but few of those versions compare to the Japanese-made Hario Cold Brew Bottle created in partnership with Blue Bottle Coffee. Glass, silicone rubber, polypropylene, and polyester construction. 750ml capacity. 11.75″ tall x 3.25″ wide side. Dishwasher-safe pieces. Removable filter. After you acquire the Hario Cold Brew Coffee Maker, ground coffee, and clean water, all you need to do is put the coffee inside, fill the bottle with cold water, and wait. Ideally, you wait 12-18 hours overnight in the fridge for optimal results, but that isn’t strictly necessary if you need your caffeine fix in a less planned timeframe.
