Q. I have a VST basket. What is the best size tamper that I should buy?
For the VST baskets – 18, 20 or 22 gram basket, the most appropriate size tamper is 58.4mm for the either the 5 Star Pro or original Eazytamp.
Q: How can I measure the size of my filter basket to work out what tamper size I need?
There are few ways you can check the size of your basket:
- If you have a pair of vernia, you can use this to measure the inside of your basket. If you don’t have a vernia, you can you can measure the size of your filter basket by cutting a business card to size to fit inside the filter basket, then measure the size of the card.
- You can use a search engine and look online to check the specific dimensions for your filter basket by typing in the brand name/model of your coffee machine
- You can use the measuring guide on our website to check what size you need. For access to the measuring guide, click here.
Q: I received my tamper, but the base has superficial scratch marks on it. Does this effect the extraction I’ll get from my coffee when I use the tamper?
No. The small markings on the base of the tamper are part of the normal manufacturing process and just superficial marks. Every tamper will have a mark of one kind or another because it is stainless steel. Our stainless steel bases are machined using a lathe. When they come off the lathe they fall into a basket which contain other bases. As they touch other bases they might mark. These markings do not interfere with the quality of the tamping and make absolutely no difference to the extraction flavour or consistency of the extraction.
Q: My handle has lines marking around it, particularly near the top. Is this normal?
Yes this is normal. Our acetal handles are hand turned, not injection moulded. These lines are a normal by-process of manufacturing.
Each tamp comes with a 15-kilo spring (silver) already inserted inside the assembly.
In addition, we include a complimentary red spring with the package. This red spring is a spring that compresses 10 kilos. It is provided for home baristas who might have older style domestic coffee machines with internal water pumps that can’t handle the strength of a 15-kilo spring. We provide this spring as an option for these customers so that it doesn’t undermine the functionality of the coffee machine.
If you are using the tamper with a commercial coffee machine, or newer model one-group coffee machine for home use, we recommend you use the 15-kilo spring.
Q: How do the pre-calibrated pressure springs work?
The springs used in our coffee tampers work in the following way.
When the springs are inserted into the assembly they are placed under pressure. In order to exert the pre-calibrated pressure of either, for example 10 or 15 kilos (red or silver spring), the spring travels 3mm inside of the assembly. For example, when the 10 kilos spring is used inside of the assembly, it is placed under 7 kilos of pressure. When the spring travels 3mm (as the barista pushes down the handle of the tamper, and the handle reaches the base of the tamper) it compresses the pre-calibrated 10 kilos of pressure. The same science applies for the 15 kilo spring. When the 15 kilo spring is used inside of the assembly, it is placed under 10 kilos of pressure. When the spring travels 3mm (as the barista pushes down the handle of the tamper and the handle reaches the base of the tamper) it compresses the pre-calibrated 15 kilos of pressure.
Between these two springs it is therefore possible for a barista to manually compress anywhere from 7-15 kilos of pressure (if they so desire).
Q: How do I know what thickness of compression base I should buy for the Double Spring Leveller Tamper (Eazytamp 5 Star Pro) coffee tamper?
If you’re using VST, IMS or other competition filter baskets (which are usually sold as separate accessories to coffee machines), then we recommend that you buy the 7.5mm thick compression base.
For all other filter baskets, including those that come standard with your coffee machine, the 7.5mm thick compression base will also be suitable.
