Motta Competition Tamper 58.4mm (Black) Flat Base
Motta Competition Tamper 58.4mm Flat Base.
This is a Bella Barista recommended item.
Especially if you want to maximise the bottomless portafilter shot. *If you're not quite sure what this is you will find plenty of slow mo you tube clips.
Combined with a competition basket by IMS or VST this tamper allows a nice snug fit, preventing side channelling.
Therefore, better extraction, better tasting shot. Also less spitting or side pin-holing.
Even with standard double baskets, this helps prevent side channelling, leading to a better shot.
