Experimenting with Bonavita Brewing Temperatures
Not Just Your Average Auto Brewer
I think we've made it obvious that we really love the Bonavita coffee maker. The Bonavita has proven itself to be temperature stable, producing a consistently quality cup of coffee, time after time, with lots of ease. You could even consider the Bonavita a hot water deliver system; you decide the dose, the grind, and even the dripper (several drippers fit the Bonavita).
Maintains a Good, Consistent Temperature
Several months ago we ran tests on the Bonavita to determine if we were willing to stand behind this maker and sell it. Of course the biggest thing we were concerned with was whether it brewed hot enough, and whether it held that temperature consistently throughout the entirety of the brewing process. We used cold, fresh, filtered tap water, which at our tap is around 65 degrees. At this temperature, the water from the brew head was consistently delivered at 205 degrees, meaning that the bed temperature was around 202-203, a great temperature for brewing most coffees, and within the SCAA standard for brewing.
The other day, we had a delicious coffee in the office, and were wanting to brew a large batch using the Bonavita. This particular coffee was a high-elevation, very lightly developed coffee, with the best results in pour-over brewing coming from very hot brewing temperatures, between 206-208 from the kettle. So we wondered, would using lukewarm water affect the temperature at the brew head? The answer as you can tell from the title was an ecstatic YES! While we would never recommend using really hot water with the Bonavita, we have found that you can safely manipulate the brew head temperature by adjusting the temperature of water in the reservoir from cool to lukewarm. We decided to test this several times, using a basic 500mL and 30g of coffee, and here are three numbers that represent our overall results:
- 95 degrees in the reservoir = 206-207 degrees coffee bed temperature
- 65 degrees in the reservoir = 202-203 degrees coffee bed temperature
- 45 degrees in the reservoir = 196-197 degrees coffee bed temperature
This is a pretty exciting finding! The already excellent Bonavita maker becomes an even more versatile brewing option. Our examples should work for you, barring differences in ambient room temperature (our thermostat was reading 70 degrees) and voltage drawn from the outlet (extension cords, other appliances sharing the outlet). Run your own experiments and see what you find! And for more information on the Bonavita brewers, check out our glass and thermal models.

The Fretta Iced Coffee Brewer is Hario's answer to brewing the perfect cup of iced coffee. Hario has combined their famous V60 brewer with a decanter and plastic diffuser to assure that the coffee is quickly cooled by hitting ice immediately after the brewing process. This quick heat transition is important in conserving the flavor of the coffee. The Fretta comes with 10 size 02 paper filters. We recommend that you purchase extra filters as well. To do this select filters as an add-on from the options on the right or go to our Hario 02 filter listing. Also recommend is a pouring kettle. We offer both the Hario Buono Kettle as well as the Kalita Wave Pot Kettle in the drop-down menu on the right.
$53.00Hario's stainless steel water kettle, the V60 Buono, has been spotted popping up in coffee houses and the kitchens of baristas for some time now. A detailed search on the web will reveal, for the moment at least, that the Buono seems to be widely accepted as the most useful pouring kettle available. What makes this kettle so popular amongst pour-over enthusiasts? Several reasons stand out.
First, the thin pouring spout enables greater pouring precision as well as a slower, more consistent and controlled rate of pour, both of which are very helpful in achieving a precise, prolonged extraction.
Second, the stainless steel construction and large 1 liter capacity contribute toward keeping up the brew temperature for the duration of the entire brew cycle.
Third, the ergonomics involved in the design of the kettle help to make using it much easier. This may not seem like much, but if you're brewing large batches of coffee and pouring for three or more minutes per batch, doing several batches of coffee will quickly become a chore if your kettle doesn't cooperate with you.
Combine all of these facets with the fact that the Buono is manufactured by Hario, a very popular name in the coffee-brewing community, and the kettle's popularity is easily understood. For best results, combine the Buono with a V60 Dripper or Chemex to get a truly exceptional cup of coffee.
