The Kalita glass dripper, with its flat bottom filter providing an even brewing path and three holes in the bottom, has long been our favorite method for producing a fuller and more flavorful extraction. Additionally, the glass material effectively insulates the brew mass, preserving heat and preventing loss to the surroundings. Available in two sizes, the Kalita glass dripper is perfect for 1-2 cups with the 155 size or 2-6 cups with the 185 size. Don't forget to purchase the corresponding sized paper filters for use with this product. Details & Care Made of heat-resistant glass with a Polypropylene brim. Made in China. Dishwasher safe. For better brewing results, warm the dripper up before you start brewing.
