A group of highly caffeinated engineers, designers, and entrepreneurs have reinvented the coffee maker. Currently seeking funding on Kickstarter, the Bonaverde Coffee Changers developed the world’s first roast-grind-brew coffee machine, working to close the gap between the coffee farmer and consumer.

“We are aiming for a kitchen appliance that is affordable,” says Hans Stier, founder and CEO of Bonaverde Coffee. “We tested it, and we drank a lot of coffee.”

With 135 working prototypes, and more than 15,000 people testing the product, Bonaverde worked to develop the best brew – definitely copious coffee consumption.

After 18 months of closed beta testing, the company has arrived at their 5th generation of prototypes. “We've been through an intensive trial and error phase and, thanks to that, have identified all remotely possible flaws to this machine,” says Stier. “Our solid core technology has passed the reality check.”

This technology includes the roasting, grinding, and brewing mechanisms which work together in one machine. “There are so many things that you can adjust, and we are still working on the dripping method,” explains Stier. The primary focus has been on the roasting and grinding, the most important components according to Stier.

Using a rotary system, the roasting mechanism is enclosed in a high-alloyed stainless steel container. A ventilation system absorbs the smoke from the roasting process, which takes around three to four minutes and also accounts for degassing from the beans as they are cooled with a fan before grinding.

Producing a fine ground coffee powder in less than 90 seconds, the disc grinder is made from a high quality ceramic cone grinder. “Ceramic doesn’t absorb heat or expend heat to the beans. It’s a very reliable and lasting material,” Stier explains.

Although the coffee pot prototype currently uses a lot of plastic, many of the components will be changed to aluminum before manufacturing. The housing will remain plastic. “If we didn’t do it in plastic, the machine would cost around $1,000. We really want to have something that most people can afford.”

The machine design was crowd sourced from designers from all over the world. “50,000 registered designers interact with each other, put up design ideas and then comment on each other. By commenting, they gain karma points, and in the end those points are what make one idea superior over the other.”

A manufacturing partner has been signed, and the timeline set. In the future, the company is looking to introduce a second and third manufacturer to make sure the competition between them is high enough to assure that the prices for the consumer will always be low.

“If there is only one manufacturer then you could basically set the price to the ceiling,” says Stier. “But it doesn’t make sense to have a few very high priced products on the market. It’s more useful to bring them into the market to make sure that it is available to everyone.”

The campaign has had its skeptics, but it has caught the attention of many, more than doubling their original goal of $130,000 with $419,305 raised from 1,385 backers and 13 days left to go.
