我用半加仑Mason jar＋过滤网，粗磨咖啡粉加入纯净水，入冰箱浸泡24至36小时左右。Mason jar过滤网非常好用，两层密密的网，过滤得很干净，（推荐KLEIN Cold Brew Kit – Cold Brew Coffee Maker – Wide Mouth Mason Jar Filter for Brewing Coffee Concentrate and Infused Tea at Home – 100 Micron Mesh – Stainless Steel – Spoon, Seal & Gift Box Included https://www.amazon.com/dp/B0721RVRYN/ref=cm_sw_r_cp_tai_qaucFbBC5M0B7）
过滤后装瓶密封保存，冰箱冷藏一个星期后仍然好味
喝时自我选择浓淡度加冰加糖
也可以添加牛奶或Cream或焦糖、巧克力⋯随个人喜好选择。冷泡咖啡的味道：少了热咖啡的苦味，多了咖啡的浓香味，是夏天冰饮的最好选择
