Introducing the only vacuum brewing system that satisfies both coffee roasters and their fellow scientists. It works via a high tech heating system developed especially for the Bodum Santos. No paper filters to make the coffee dull - just a small, easy-to-clean micron nylon filter for a smooth tasting coffee. The entire brewing process is completely contained so no aroma escapes and temperature is ideal and consistent. Enjoy up to 12 cups in just eight minutes, and set the timer for that first cup of the morning.
