Vacuum-Powered Machine Brews Artisanal Tea In One Minute
BKON Craft Brewer completely infuses a cup in 60 seconds.
Tea-making is thought of as more slow and contemplative than coffee-making, but sometimes you just need your dose of caffeine now. Technology has now touched the world of tea brewing in the form of reverse atmospheric infusion (RAIN). The device that executes this complex process is the BKON Craft Brewer, and it blows other methods out of the water in terms of speed (60 seconds to completely infuse a cup) and consistency.
What’s RAIN? Loose tea leaves and water are placed in a vacuum chamber, and then air is sucked out to create a vacuum above the liquid. This draws the flavor of the tea out of the leaves in the form of a gas. Water takes the usual place of air as soon as the vacuum is released, causing the tea to infuse immediately. The complexity of the process makes for twice as many variables that can be controlled by the person making the tea, including vacuum depth, duration and frequency. Typical brewing methods only use contact time, water temperature and agitation. The creators of the Craft Brewer also claim that the tea’s flavor is made more vibrant through the method, in part because the reduced amount of contact with hot water leads to less flavor damage. “You taste the tea and not the water,” said Rishi Tea’s Josh Kaiser at a tasting.
