Tamping mat and station

Gives the portafilter one fixed, non-slip place to be tamped, with the spouts hanging clear of the counter.

A resilient elastomer pad, usually with a raised corner or a stepped edge that captures the portafilter's rim so the body sits level while the spouts overhang. Mechanically it does two obvious things and one that matters more. The obvious ones: it stops the portafilter sliding under a load that is never perfectly vertical, and it keeps the spouts off a hard surface, because spouts bent even slightly split the stream and dribble down the outside of a cup. The one that matters more is that it fixes the POSITION. Tamping consistency is a posture problem before it is a technique problem — the same barista tamping at the counter edge, then at the back of the bench, then over the drip tray, produces three different wrist angles and three different beds. A mat placed once, at a height and a distance chosen for the person who works there, turns tamping into a repeatable movement. That is why a mat that has migrated to wherever there was space is a mat that has stopped doing its main job while still doing both of its obvious ones.

• Set the tamping position for the person who works there, then buy the mat that holds that position. Height under the tamping point and distance from the counter edge decide the wrist angle, and the wrist angle decides both the levelness of the tamp and whether that barista is still comfortable in month six. Everything else in this entry is secondary to that sentence.
• Choose a captured edge over a flat pad unless the position is already fixed by a holder. A mat that does not tell the portafilter where to sit is a spout protector, which is a real but much smaller job than the one it is usually bought for.
• Insist that the mat lifts out and washes. It sits in the wettest, most coffee-covered strip of the bar and it is a food-contact surface; a mat glued down or wedged behind the grinder becomes a permanent reservoir that gets wiped around rather than cleaned. Check underneath one that has been in service — that is the whole argument.
• Size it to the largest portafilter you own with its spouts clear, and check the overhang against what is below. A mat that leaves the spouts hanging over the knock box opening is a mat that will drop grounds into the box, which is fine, or over the drip tray, which is not.
• Buy the material for grip when wet, not for feel when dry. Everything on this counter is wet by the middle of a shift, and a pad that grips dry and slides wet is worse than no pad because the barista has stopped bracing for it.
• If a fixed tamping station is on the table, treat it as an ergonomic purchase and specify it with the counter. It is the one item in this category that materially reduces repetitive load, and it is also the one that cannot be added later without either drilling a finished worktop or accepting a clamp.
• Give the mat a written home in the opening routine. A mat's whole value is that it is in the same place every time; a mat that moves during the day is delivering spout protection and nothing else, and nobody will notice because both the mat and the problem are still there.
