During the downtime at this week’s tradeshow, I got into a conversation with our booth neighbors about coffee. The other guys were telling me that the secret to Dunkin Donuts‘s famed coffee is the osmosis filtering they do with the water.
That got me wondering if any consumer-level coffeemakers exist which also “brew” the water, too. It might not be as complicated as osmosis, but a coffeemaker which highly filtered the water, or distilled it even, would make great-tasting coffee I would think.
Then again, distilled water often tastes flat, which makes sense since distilling it removes all but the water molecules themselves.
I wonder how a coffeemaker with superior filtering could be built.
