The YAMA GLASS Cold Brew Tower is in a league of its own. Made from premium hand blown borosilicate glass by master glass blowers these towers ensure the highest quality and craftsmanship in every brew cycle. We didn’t skip any corners when it comes to the overall build quality and brewing experience. This is why coffee shops around the world trust the YAMA Cold Brew Tower to deliver cold brew to their customers. Here is how it works: Ice and water are placed in the top jar, and by regulating the dripping water through the valve in the center, coffee is steeped and ends up in the carafe at the bottom of the tower. Through a unique 3 hour brewing process using pure ice water, ice drip coffee produces a unique flavor not found in regular brewed coffee - it is acidic free and smooth as can be. Just put the water and coffee grounds into the brewer and you are ready to go. A permanent ceramic filter mechanism is included and is available in a brown stain finish. This coffee maker holds 32 oz. By slowly brewing your coffee with ice water, the harsher oils in your ground coffee are not brought out. The final brew is richer and smoother than what you would find in an immersion style cold brewer. Its unique and crafty design is the perfect conversation piece for any coffee shop, home or office.
