Years of research have resulted in a technological breakthrough in coffeemaking: air-pressure brewing. Air-pressure brewing shortens filtering time to 20 seconds, avoiding the bitterness of long processes like drip brewing. Air pressure also gently squeezes the last goodness from grounds, further enriching flavor. In addition, our AeroPress espresso maker uses total immersion of grounds in water, resulting in rapid, yet robust extraction of flavor. Makes one to four cups of coffee or espresso in just one minute. Hand wash. Made in USA.
