This reusable ground coffee kneading bag simplifies the process of blooming your coffee prior to loading in the HIVE Cafe or Ace Brewer. Simply put 3-4 lbs of ground coffee and 32-48 oz of water in the Bloom Bag, knead the mixture, for a minute or two through the pliable silicone bag and then feed the bloomed grounds into the Ace brew cylinder or Hive brew cell through the Bloom Bag Spout. Faster, cleaner, and easier than mixing in a cambra or mixing bowl. Bloom Bag is easy to clean with the top and bottom large access openings.
