Here's a potential solution for people who have to limit the amount of coffee they drink because of acid reflux. Hammacher Schlemmer has launched the Acid-Reducing Flavor-Enhancing Coffee Hourglass. Hammacher Schlemmer says this coffee maker brews with cold water to reduce the acid in coffee by up to 69.6%. The Hourglass does not reguire electricity - it uses gravity and time.
The user combines coarsely ground coffee beans with water in the brewing chamber and allows the coffee to infuse with the water for 12 to 24 hours. When the infusion process is complete, the hourglass is turned upside-down and 16 oz. of coffee extract drains through a reusable stainless steel filter and into the extract chamber. The extract makes up to eight 8-oz. cups of coffee per brewing cycle and the extract can be kept in the included carafe and stored in a refrigerator for up to two weeks.
The Coffee Hourglass can be purchased here for $79.95.
