Winner of Coffee Geek’s 2006 Editor Choice Award for the Best Training Tool category, the Espro Calibrated Tamper features world class construction. This unique tamper automatically clicks when 30 pounds of force has been exerted onto it, alerting you when you have reached the proper amount of tamp pressure for espresso extraction. These Espro tampers feature stainless steel convex bases and are available in 53, 57 and 58mm sizes. The 53 and 58mm tampers have polished black handles. The 57mm tamper comes with a red handle. Espro Calibrated Tampers are designed, machined and assembled in Vancouver Canada.
Considering using this to reduce variables within a large team of baristas. We have a very high turnover of customers and produce around 300 coffees a day, would this tamper be able to withstand that kind o level of usage? And if so, how long before I'd have to replace the tamper? Thanks.
As this product is designed for light-duty home use, I would recommend against using it in a commercial environment. In our experience, you'd be expecting to replace the batteries fairly frequently in that sort of environment simply due to how often you're polling the load sensor and displaying its reading. For commercial environments, we generally recommend solid metal tamps.
Why would I choose the convex vs. the flat base?
A great question with not a right answer. It has been a debate for a long time and both sides have valid points. Read this -http://www.coffeegeek.com/forums/worldregional/australasia/148871?Page=1
I think it is you buy whatever philosphy you would like to believe. I have always been a flat guy, and probably always will be.
