Vacuuming brewing was a common method early in the 20th century, before paper coffee filters became widely available. It takes a bit longer, but once you have tried it a couple times the process is fast and simple. And your incentive to use these devices will be clear: coffee with pronounced body and no sediment; very clean and crisp; a cup where flavors are dramatic and heightened in every respect. Delicate coffees like Africans and Central Americans are especially suited for vacuum brewing.
Is vacuum brewing for everyone? No. One person's "clean" is another person's "weak"! If you like French Press brewing, the clarity of this cup might seem thin to you. It is a matter of preference.
