How many grams of coffee do I need in my portafilter?
A.G.J. Van der MolenSometimes it remains a challenge to make that beautiful espresso.
In coffee houses and on YouTube you see the most fantastic espresso passing by: thick, syrupy and dark with hazelnut tones. But your espresso often comes out differently: too fast or too slow, watery and with little crema.
We've put together a few tricks to help you make better espresso.
1. How many grams should your filter holder hold?
Single (espresso) cup: A single espresso cup usually holds between 8 and 12 grams of ground coffee.
Double (espresso) cup: A double espresso cup usually contains between 18 and 22 grams of ground espresso beans .
Do you really want to get the most out of your espresso? Please buy a scale! It may seem easy to estimate the number of grams yourself, but even a deviation of 0.2 grams affects the taste and flow time. By weighing the same amount of coffee every time, you ensure a perfect balance in extraction and a consistent espresso full of flavor. Over time, you may sometimes let go of the scale, but keep it at hand in case your flow is not correct. That way you always stay in control of your espresso!

2. How do I know the exact number of grams for my filter holder? Tips and Tricks!
Not all espresso machine brands use the same portafilters – some are larger, smaller, deeper or narrower. This can make it a challenge to find the right amount of coffee for your machine. The size of your portafilter will affect the amount of ground coffee you use, which will affect the flavor and intensity of your espresso. Experiment with small adjustments in grams to find the ideal recipe that suits your machine and taste preference. Start with a standard amount and adjust in half-gram increments for optimal extraction!
Besides using an espresso scale , there are a few tricks.
Trick 1: A mountain of coffee.
Fill your filter holder to the brim with a small mound on top. Press the ground coffee with the tamper to about half a centimeter below the rim of the filter holder. Then you have enough coffee to make your single or double espresso. A tamping station helps enormously with pressing your coffee straight and well.

Trick 2: Screw in the filter holder.
Another trick you can use when screwing the filter holder into your espresso machine. If you can screw the filter holder all the way through, there is not enough coffee in your container.
By turning I mean that when you turn the filter holder in the group of your espresso machine, the lever of your filter holder does not get stuck on the left or in the middle, but turns to the right. So turned too far.
If you can't even get the filter holder in the middle of the group, it's too full. So middle is best.

Trick 3: Use a shot glass.
By using a shot glass , you always know how much 'output' you have. A single espresso is standard 30ml. A double espresso is standard 60ml.
A common mistake is that too much is 'estimated' when letting the espresso run through. Always stop your espresso at 30ml or 60ml (for a double).
Is your espresso running slower than 25 seconds? Then your grind is too fine or there is too much coffee in your filter holder. If your shot glass is already filled after 15 seconds, then your grind is too coarse or you have too little coffee in your filter holder.

Trick 4: Too watery or too dry.
Another indicator of too much or too little coffee in your portafilter is a too wet or too dry 'puck'. A 'puck' is the term for the residue after extraction; the puck that you eventually knock out and throw away. A too wet puck, with a lot of water on top, is often a sign of too little coffee in your portafilter or a grind that is too fine. The reverse is also true: a puck that easily falls apart in your knockout drawer when knocked out is a sign of too much coffee or a grind that is too coarse.
