Consistency is the hardest part of tamping to get right by hand. The Muvna Constant Pressure Tamper takes the guesswork out of it with a spring-loaded mechanism that delivers the same force on every shot, regardless of who's behind the machine. An auto-rebound action keeps the tamp level as it compresses, so the puck stays flat and the pressure stays even across the bed. Built around a 304 stainless steel base and sized for standard 58mm portafilters, it's a straightforward upgrade for home baristas chasing repeatable extractions and a sensible bit of kit for busy cafe benches where multiple staff are pulling shots.
