It’s grinding time!

I love coffee. I also love tonnes of other drinks, but in this post, I will be concetrating on coffee; more specifically, I will be writing a short review about a new coffee grinder I have just bought. This blog post has in no way been sponsored by Graef!

I got into coffee at a very late point in my life, namely in the autmn of 2018. Before then, I mainly consumed tea (which I still do) and I had always thought of coffee as something that was horribly bitter and without nuance. But then I thought to myself that I may have just had really awful coffee that was badly prepared and I therefore decided to give coffee another chance and head to the local coffee roastery we have in town to try the lightest coffee they make and it turned out to be very tasty! Since then, I developed a taste for stronger coffees, in particular espresso, and I even bought an espresso machine about half a year ago. I had been using a Porlex Mini to grind my coffee beans up until a few days ago and it worked (and still does) very well. The problem I had with the Porlex, though, was that it just took ages to grind enough coffee for an espresso. If I turned the handle as quickly as I could, it would still take at least one and a half minutes to grind my beans; considering the fact that I drink quite a lot of coffee means that I could spend around 10 minutes of my day just grinding coffee. Now, I do realise this isn’t a very long time but it adds up. Additionally, it was just very tiring having to manually grind so much coffee all the time and if I wanted to change the grind size I would have to completely clean the grinder (that’s what they recommend you do in the manual (you may be able to turn the adjusting nut without cleaning out all the coffee from the grind mechanism, but I didn’t want to risk breaking my grinder). Therefore, I started looking for an automatic grinder and I have finally found one I am very happy with: The Graef CM 702.

Overview of the grinder

The coffee bean container

The Graef cost me €75 on Amazon which makes it about 35% (€20) more expensive than my Porlex. It is specifically designed for use with a portafilter but the packaging includes a plastic container for grinding coffee into should you happen to be grinding your coffee for your hand filter (or Aeropress or French Press) instead. It feels very substantial (most likely due to the weight of over two pounds) even though it is made out of plastic. The coffee bean container can hold up to 250g (½ lbs) of coffee beans and they recommend you to fill it up regularly as the grinding mechanism needs the weight of the beans to function properly. The conical burrs themselves are made out of stainless steel and the upper part of the burrs can be taken out of the machine for easy cleaning which they recommend you do once a week (yea… not gonna happen). Speaking of the grinding mechanism, the grind size can be set from 1 (finest) to 25 (coarsest) and I found that 5 works very well for my espresso needs.

How does it work?

Setting up the grinder is a very simple task, even though I do believe they could’ve put some more information into the manual. The first thing I noticed was how quickly I got my coffee ground compared to the Porlex Mini; grinding enough coffee for a double espresso takes about 10 to 20 seconds. The grinds look very even to me as well, at least on the setting I’ve been grinding; I haven’t tried grinding on the coarser settings yet. It makes quite a lot of noise, however, but I believe that is to be expected from a grinder such as this one. Grinding directly into the portafilter works very well and it does so without creating a huge mess (even though some coffee inevitably misses the portafilter anyway).


All in all, I believe this is one of the best grind-on-demand coffee grinders you can get for pretty cheap price.
