You have just invested in a new espresso machine but it comes with one of those cheap, plastic tampers that feels like it cost about $10 to make, what do you do? Well you chuck it in the bin and invest in a decent one of course. Espresso is hard enough to make as it is so don’t make it even harder for yourself by trying to do it with a cheap tamper! 

However, if you begin to look you will quickly realise that there are almost innumerable tampers available on the market in literally in every shape, colour and size. We have summarised what we think are five great options.

What is an Espresso Tamper?

An Espresso Tamper is a simple but essential tool when it comes to espresso making. It is used to evenly compress coffee grinds in the portafilter.

Tamping is really pretty simple, you are aiming to compress the grinds until the tamper stops moving down, and keep it level to promote even extraction. 

Why do you need to compress the grinds?

When you fill your portafilter with coffee there is a lot of air between the grinds, if you pulled a shot without tamping, the water would speed through and you would get a very unextracted and unpleasant shot. Tamping compresses the grinds to remove all the empty space and produces an undifferentiated front for water trying to pass through. Water will consequently have to force its way through the grinds which allows time to extract flavour and (in theory anyway!) produce that rich shot of espresso you are looking for. 

While tamping pressure is important (you should be aiming for around 20-30 pounds) having an even and consistent tamp is more important. This means that when you are dialing in beans the grind size will determine the rate of flow rather than tamping. 

Problems that can occur when tamping:

  • Channeling– Water will always try to take the path of least resistance. An unevenly tamped portafilter will have regions that are less dense which allows water to easily make a path through it (channeling). The problem with this is that part of the grinds will end up being over extracted while other parts will end up under extracted. A properly tamped puck should present an undifferentiated front to the water. Channeling can happen if you don’t tamp evenly as one area of the portafilter will end up being more heavily compacted than the rest. Alternatively, if you knock the portafilter after tamping this creates air pockets at the edges.
  • Suctioning- If a tamper is too tight a fit in the basket it can have a suctioning effect when removing the tamper. If you pull the tamper out too quickly, it pulls the compacted puck out. This means that the compacted coffee grounds are disturbed which, in turn, produces air pockets. To counteract this some tampers have a ridge on the side. 

What to look for in a Tamper

When it comes to looking for a tamper the most important thing is to get the right size. After that it all comes down to personal preference! Get one that feels good to hold. The shape doesn’t matter too much and if used correctly doesn’t make much impact on extraction. 

Size of the Tamper

Tampers come in a wide variety of sizes ranging from 48mm to 58mm. The most common size is 58mm which is commercial size. However, some entry level machines have smaller portafilters which require a smaller tamper. If you are not sure what size to get, just measure the inside diameter of your portafilter basket and get a tamper that is slightly smaller.

Weight of the Tamper

The more a tamper weighs the easier it is to achieve the 30lbs of pressure required when tamping. Ideally, you should opt for a tamper that weighs around 1-2 pounds, preferably made of stainless steel not plastic.

Shape of the base

If you are new to the world of tamping you may not have come across the debate in the coffee world over what shape of tamper works the best. To keep it simple, there are generally two schools of thought: Flat vs Convex. A flat tamper is exactly that… Flat! Whereas a convex tamper has a base that is slightly bulged out. The idea of this is that it helps push coffee towards the edges of the portafilter preventing channelling along the sides. Here at thecoffeefolk we use a flat tamper but a convex tamper works just as well.  

Handle

Consider what material you would like the handle to be made of. Consider how it will feel when in use. If you have smaller hands you might like a smaller handle and visa versa.

Calibrated or not..?

A calibrated tamper basically has a handle separated from the base, when tamping down the handle and base connect and click when pushed to around 30 pounds of pressure. This is great for beginners who want to make sure they are applying the right amount of pressure. It is also good if you have multiple people using the same machine. It takes tamping out of the variables you need to alter when dialing in beans. 

Material

Tampers come in all different materials starting with low quality plastic (please avoid!) to stainless steel tampers. It is best to opt for stainless steel which lasts longer and is just better in every imaginable way. 

Appearance

Do you want your tamper personalised with an engraved handle, a carved wooden handle… you want it they got it! There are endless options when it comes to tampers so choose one you will love for life!

Cost

Tampers vary in cost from as little as $4 to up to $200 for a custom made one.
