Blue Bottle Coffee is a specialty coffee roaster focused on discovering and preserving the true nature of coffee. They use only the finest certified organic coffees, and when available, coffees that are farmed traditionally without pesticides. After roasting, coffee beans exhale carbon dioxide for several hours. Instead of keeping the Blue Bottle beans in bins, they are mixed in blends and bagged within four hours to harness carbon dioxide and keep oxygen (and oxidation) out of the bags. Blue Bottle never pre-blends their coffees, thus assuring the ideal roast profile for each bean. All varietals are roasted individually and then mixed into the blends, producing an award-winning cup of coffee.
