BREWING A BETTER CUP
Your brewer comes with an optional pre-infusion mode which slows the introduction
of water to optimize flavor in the cup. Our unique pre-infusion mode creates a bloom
inside the filter basket. The bloom is a process in which gasses from the coffee are
released as the water hits the grounds. This causes the grounds to grow and rise.
The CO2 that is inside the bean is purged out and replaced with the water. This
begins the brewing and flavor extraction process. The bloom is not only a chemical
reaction, it’s also a relevant part of the brewing process and enhances the aromas
and flavors of the cup you brew.
• This Bonavita coffee brewer is engineered to heat the brewing water to with-
in the 198°- 205°F (92°-96°C ) range. The heating elements in the Bonavita
coffee brewers are designed to deliver the correct temperature water over the
correct brewing time.
• For ideal extraction levels, brew your coffee in 6-8 cup batches, with fresh,
filtered, cold water.
• Brewing time is about 6 minutes for 8 cups of coffee. This will allow for proper
water flow and saturation time.
• The quality of the coffee has a great impact on brewed coffee’s flavor. Using
freshly roasted beans and grinding the beans just before brewing are important
considerations. We recommend using coffee within a couple of weeks of its
roast date. Air tight storage will help extend your coffee’s lifespan.
• Grinding coffee is another key point on the timeline of flavor and perishability.
Once coffee is ground the air begins to attack essential oils and other volatile
flavor components. It’s only a matter of hours before most of the ground cof-
fee’s aroma has evaporated. Sometimes pre-grinding can’t be avoided, but if it
can, delay until shortly before brewing.
• For the most consistent results, Bonavita recommends measuring coffee by
weight, using 10 grams of coffee per cup.
• Measuring coffee by volume is less consistent. For example, two tablespoons
of drip grind coffee can weigh between 6 grams of dark roast coffee to 11
grams of light roast coffee. Bonavita recommends beginning with two level
tablespoons of medium coarse drip grind coffee as a starting point with your
preferred roast, and adjust according to your taste.
• Keep the filter basket, water tank, and carafe clean.
• For maximum heat retention we recommend rinsing the carafe with hot water
shortly before the brew begins.
