So Bob started tinkering, trying to replicate his grandfather’s cold-brewed success with an easier, more modern coffeemaker. He teamed with Todd Maas and their first prototype was made with a mason jar, beer cozy and duct tape.
After a few years of refinements, Bob and Todd created the sleek, portable Hourglass. Just add coffee grounds (or loose tea), cover with cold water, and let the grounds steep overnight or for up to 72 hours. After steeping, flip the unit and pour the extract into a canteen (included with the system). When you’re ready for some java, just add the concentrated extract to hot water for traditional coffee, or ice it down for cold coffee drinks. You can adjust the water ratio depending on how strong you like your coffee, and the extract can be refrigerated for up to two weeks.
Indeed, it’s got all the qualities of a great Grommet: Inventive, with a spoonful of family history and no trace of bitterness. Good to the last drop!
