Sometimes, before that first cup of coffee, drowsiness gives us the drop-sies. Luckily the Kalita Wave Series has a stainless steel version of their beautiful (and breakable) glass version. Both coffee drippers incorporate a flat-bottom design with a patented “Wave” filter. Together they create an even coffee extraction that you control. Take a little time to perfect your pour and this coffee dripper design will amaze you with delicious results.The 155 Wave dripper is optimized for brewing a single-serving of brewed coffee. We recommend this dripper for 1-2 tablespoons of coffee, yielding 12-16 ounces of brewed coffee.
