Drinking coffee every single day, you may have never thought about using a coffee scale to weigh your beans and water. Is it really worth it? Absolutely yes. Scale is just the key to the tastier, more balanced, and reliably delicious coffee. Here’s why.


Generally, the ratio 1:15 and 1:19 (coffee: water) are considered excellent for brewing coffee. With a scale to weigh out the right amounts, you’ll have a well-balanced cup.

Improper ratio leads to bad taste. For instance, too much water and too little coffee results in over-extraction — your coffee tastes bitter, and you’ll fall asleep soon at work. The same is true with under-extracted coffee, which means too little water and too much coffee.

A tablespoon is convenient, but it doesn’t guarantee the consistency of a balanced coffee. Maybe one day it’s sour, the next day it’s perfect, and the third day it’s bitter. Luckily, a precise measurement will eliminate the problem by ensuring that the ratio of coffee to water is never unbalanced again.

People tossing scoops of coffee beans into the grinder each time is going to run out of stock a lot quicker than those using a scale. Here’s an example. A friend of mine told me he typically uses a couple of scoops of beans for each cup, while I generally use 20g. We both started with 12 ounces of beans. The result? He had 20 cups, while I had 28. The difference is big, isn’t it?

How to select a coffee scale

Choosing a scale for coffee brewing is easy, but it would be better if doing a bit of a search ahead of time. Here are some features that you can look for:

  • Measurements in grams and ounces
  • 1,000-2,000 gram capacity
  • Rapid response time
  • Measuring platform large enough for a French press or large mug

If you are still not sure which one to choose, I suggest you take a look at Jennings CJ4000, which is the most recommended scale for coffee enthusiasts. It can measure in 0.5g increments, while the others in the similar price category can only measure in 1g increments. Other frequently recommended scales include Acaia Pearl, Hario Scale, the American Weight Scale.

Just enjoy brewing!
