Additional Details ------------------------------ Bullet point: BUNN BREWS DIFFERENTLY - The BUNN Speed Brew uses an internal commercial grade stainless steel hot water tank that keeps 70oz of water always hot so you can quickly brew at the flip of a lid..Note: 1)Too coarse a grind, too little coffee, or insufficiently tamping the grounds before brewing can all lead to inadequate pressure for a proper brew. 2)It is important to note that the amount of espresso extracted will vary depending on the grind size and amount and reprogramming may be needed when the size and amount are adjusted
