How BKON’s Vacuum Brewer Perfects Coffee Extraction
If you’ve ever wondered why some coffees taste thin or overly bitter despite using high-quality beans, the issue often lies not in the roast or the beans themselves — but in how the flavors were pulled from the grounds. The science of extraction is where great coffee is won or lost, and lately, innovators have been turning to some surprising techniques to get better results.
The BKON brewer can extract full flavor from coffee or tea in just 60–90 seconds using a patented vacuum process. Developed by Dean & Lou Vastardis, it controls water volume, temperature, pressure, and cycles via app, and has attracted interest from Starbucks and specialty coffee labs.
What Is the BKON Brewer?
The BKON brewer is an automated vacuum extraction device built by Dean & Lou Vastardis, a company known for making professional beverage equipment for brands like Franke and Rishi. Though originally designed with tea in mind, the machine’s vacuum injection system works with any organic material — especially coffee. Its transparent chamber lets users watch as controlled air pressure and water precisely extract flavor compounds without degrading the cell structure of the grounds.
How Does Vacuum Extraction Work in Coffee?

Unlike traditional drip or immersion methods, the BKON uses what’s called “reverse air pressure injection.” Instead of forcing steam or applying high agitation, it gently lowers air pressure to create a natural, low-temperature boiling effect. This preserves the integrity of coffee particles while extracting aroma and flavor molecules more efficiently. According to the company, where conventional brewers might take around seven minutes, BKON achieves full extraction in just 90 seconds — with no compromise on taste or aroma.
The vacuum process is notably gentle. There’s no violent bubbling or extreme heat. Instead, temperature-controlled water is cycled through the coffee bed in precise, programmable intervals. Testers have used it on various teas with excellent results, and it’s been successfully adapted for coffee and even experimental liquids like oils.
How Is the BKON Controlled and Customized?
Every variable in the BKON brew cycle is managed through a connected smart device. Users control water volume, temperature (within a precise range), cycle count, pressure levels, brew duration, and infusion depth via a companion app. That includes programming multiple sequential water infusions — such as a 60 to 90-second continuous pour — to replicate or innovate upon manual brew methods.

The machine also features custom rotatable filters tailored for both coffee and tea, and offers multiple cleaning modes. Onboard temperature probes ensure exact thermal control, while an independent vacuum pump and ball-valve spout maintain a stable vacuum throughout the process. Users can save and name their custom profiles directly on the device’s interface, then upload them to the cloud to share with other BKON users — a built-in community for sharing extraction recipes.
Where Is the BKON Being Used?
The BKON system has turned heads in the specialty coffee and broader beverage industries. It was featured at the SCAA (now Specialty Coffee Association) trade show, where Starbucks CEO Howard Schultz gave it a hands-on test in the exhibition booth. Two Starbucks concept stores and the New York Coffee Center have expressed strong interest. Its ability to deliver precise, repeatable extractions in a fraction of the usual time makes it appealing for both high-volume specialty environments and research-focused settings.
BKON’s inner workings include an array of temperature sensors, a dedicated vacuum system, and a sealed architecture ensured by its ball valve. All of this tech fits into a device that, while complex, is designed for precision and repeatability.

Frequently Asked Questions
How much does the BKON brewer cost?
The BKON brewer retails for $13,000 USD (approximately 81,350 CNY). The first 100 units were produced and made available starting June of the launch year.
How long does the BKON take to brew coffee?

The BKON brewer can complete a full extraction cycle in as little as 60 to 90 seconds, depending on the programmed parameters and beverage type.
What makes BKON different from regular coffee brewers?
Unlike standard drip or immersion brewers, the BKON uses a vacuum-based, reverse air pressure system to extract flavor. This method gently lowers air pressure to create a low-temperature extraction environment, preserving coffee cell structure and extracting aroma compounds more efficiently in a fraction of the time.
Can the BKON brewer be used for beverages other than coffee?
Yes. Although optimized for coffee, the BKON’s vacuum extraction technology works with tea, and has even been tested with oils and other liquids. It is designed for any organic material that can benefit from controlled pressure and temperature extraction.
Is the BKON brewer used commercially?
Yes. The BKON brewer has been tested and shown interest by major companies including Starbucks (with tests in concept stores) and the New York Coffee Center. It is also suitable for high-volume specialty coffee environments due to its speed and precision.
