Colture Grind Guide

Grind size is extremely important when it comes to brewing coffee; communicating grind sizes isn’t always easy.

We want you to enjoy coffee the way you like it, and how you prefer it to taste. However, if you feel like you want to understand the science and how it affects the final cup, here’s some tips and tricks to help you on your coffee journey.

As a starter for ten, here are some examples of grind sizes to help you establish a frame of reference. You might find that with different coffees or brewing methods, you’ll have to adjust to a coarser or finer grind.

  • A: Fine - Texture of icing sugar, suited to a moka pot
  • B: Medium-fine - Texture of granulated white sugar, suited to an AeroPress
  • C: Medium-coarse - Texture of demerara sugar, suited to drip, filter, and pour-over coffee
  • D: Coarse - Texture of rough sand, suited to a cafetière, French press or Chemex

Invest in a good coffee grinder if you can


If you drink coffee almost every day, it’s a great idea to invest in a high-quality grinder. Whether you want the top-of-the-range model on the market, or a portable hand grinder, we’ve got the goods to help you on your way. Choosing the right equipment can be overwhelming, so we’ve made it easier for you by only stocking the products we use ourselves.
By grinding beans fresh, you have greater control of how your brews will taste each and every day. On top of this, it offers greater choice and variety, because you can order a few different types of coffee beans as they’ll stay fresher for longer, given you’re grinding them on demand.

There’s no right or wrong grind size – trust your taste buds

If you think about it, history’s biggest coffee experts didn’t have a rule book to follow; it was all trial and error. With this in mind, the most important part of your coffee journey is to experiment and find your own preferred taste.

If you grind coffee and make a brew that tastes extremely bitter, it means the water has taken longer to get through the coffee bed and has been in contact with the coffee for too long. To help the water go through faster, you can make the grind coarser, brew it, and keep tasting it until the bitterness has left.

What if it’s too sour? This means the water has run through the coffee bed too quickly; it needs more particles to stick to, so grinding your coffee finer until the sourness disappears. The middle ground is called the “sweet spot”, and should taste somewhere in between. When you nail it, your coffee will have a generous balance of sweetness and nice mouthfeel. Your brew will taste well balanced, with no unpleasant sour or bitter characteristics.

Never stop experimenting

Coffee isn’t meant to be complicated – everyone has different tastes, and grinding at home puts you in greater control of how your coffee will taste. As you try new and exciting beans, there are more flavours to be discovered by experimenting with grind size. Have fun pushing your coffee to the best it can be – and remember that making coffee can be as fun as enjoying that final cup.

Whether you’re alone in the morning or spending an afternoon with a friend, coffee is a global movement that keeps evolving. Colture’s here to help you enjoy what you make of it.
