There is a small tool that is used by Baristas. Using coffee tampers, ground coffee is compressed in filter baskets. It allows water to pass through at equal rates throughout the coffee. Without using the tamper, it is really difficult to prepare coffee in the espresso machine.
Common Faq’s answered
1. Common size of tampers available
A. 57 & 58 mm are the common sizes of tampers available in the market. Going through the different brands on the leading online portals can help to know what is available.
2. What size tamper is desired for the espresso machine?
A. There are different brands and models of espresso machines used. You can get filter baskets having diameter of 57 mm & 58 mm to use. Almost all commercial machines are known to use such sized filter baskets and hence, will require the tampers to be of the same size of 57 mm or 58 mm. But there are few exceptions like commercial machines using standard size of 53 mm. So knowing your espresso machine will help you to choose the right sized tamper. For single baskets, 57mm tamper will be perfect, while for double baskets, 58mm will be suitable.
3. How to know the required tamper size?
A. The answer to this question can be determined by measuring the machine filter basket’s inner diameter. However, it is to be done with great care and not any random size should be selected.
4. Is the convex tamper much better when compared to flat version?
A. Yes, is perhaps the correct answer for majority of the people. Barista tampers work well as it is necessary for the water to run at even pace through coffee grounds. With most baskets sloping inwards towards the edge, tamp or compression is found to be more significant when compared to the one present in the middle. The convex dome part tends to compensate for this slope, thereby leading to availing better compression level, across coffee expanse present in the basket. The principle in case of straight-side walled basket, to a certain degree is the same, where wall is the barrier.
Using straight-side walled basket, principle to a particular degree is the same, as the wall acts like a barrier. Hence, as coffee when compressed contacts this wall, it is pushed from two different sides effectively.
However, the external edge ends with much more compression when compared to area of grounds which sit within more central area.
If basket bottom is flat, then first use flat bottom tamper. In case, it is not flat, convex is sure to work best.
5. What metal is used to create the bottom for the tamper?
A. Tampers are all made from stainless steel. Metal quality is superior. Most models supplied by the reputed brands are manufactured and designed to function smoothly. A good number of them also have Teflon coating all over them.
6. What wood is utilised to create wooden handle tampers?
A. It is actually unknown, unless it is clearly mentioned within the product description by the manufacturer. But workmanship provided on the tampers is definitely amazing. It is found satisfactory!
7. What make the tampers are?
A. The tampers unless clearly specified are unbranded. Manufacturer quality is quite high.
8. Does wooden tampers come with metal disk at its top to tap filter side with?
A. Disks can be viewed at the product images provided in the leading manufacturer’s websites. The disk is not replaceable or removable and if used for the purpose will scratch with time. It will be better to tap with palm of your hand, as hand tapping is found more accurate, while becoming second nature with some practice.
9. Is 58.4mm tamper really the best?
A. The tamper having 58.4mm diameter is likely to fit only 3rd party baskets and not majority of the available standard baskets, as it will be very big. Take a look at 1mm and 10mm or check a look at them on tape measure. Then look at 0.4mm directly. It is likely to be lesser by about half a millimetre of compression. When 58mm expanse is concerned, it will be much tough to notice the difference.
