Why do I need a scale to make coffee?
Using a digital scale when you are making espresso or pour-over coffee allows you to achieve consistency and control over the flavour. By precisely measuring your coffee dose and liquids you can dial in the crucial coffee-to-water brew ratio and time for delicious, repeatable results. This prevents guesswork, wasted beans and disappointing coffee!

Pour over equipment can be very basic, but to improve consistency there are a few more items that are useful. Fundamentally you only require a dripper, such as a V60, and the appropriate filter papers.
To improve the quality and consistency of your pour over, you should also consider:
- Gooseneck kettle (with temperature control)
- Electric scales (such as the Jimmy scales)
- Grinder (such as the Hiroia EDGE Ti Grinder)
If you are making more than one cup, it is nice to have a range server jug to make and serve the coffee in. We do a set that includes a glass V60, jug and filter papers, perfect for manual pour overs. When time is short, we also have an amazing Smart Brewer that can make barista quality pour overs at the press of a button!
If you want to find out more about pour over techniques, read this article:
Coffee usually tastes off due to improper extraction—too fast (sour) or too slow (bitter/burnt)—or issues with bean freshness and water quality. Sour coffee is typically under-extracted (needs finer grind/longer time), while bitter/burnt is over-extracted (needs coarser grind/shorter time) or too dark a roast.
Take a look at our article about the Best Brew Methods for African Coffee, where you will find some hints and tips about refining your brew technique:
Coffee cupping can be a brilliant way to have fun and learn more about coffee. For a detailed explanation on how to do this, you can read the article in Beyond the Bean on Coffee Cupping.
How to host your own coffee cupping
Coffee cupping experiences are on the rise, but you don’t have to go to an organised event. Find out how to host your own home cupping session
How do you identify the best coffee?
Identifying the best coffee requires farmers to grade and sort rigorously, Q-grade tasters to find the best beans, and roasters to make them sing
Grind size depends on your brew method and the roast level of the beans. Read the article on the Best Brewing Method For African Coffee to find out more
The coffee-to-water ratio varies depending on your brew method. For cupping, it is set at 8.5g:150ml water. Read the Best Brew Methods for African Coffee to work out a good ratio for your preferred drink
Throughout the brewing process achieving an even extraction is key so it makes sense that what you brew should also be an even grind size. This is why you should consider having a burr grinder rather than a blade grinder. The burr grinder has two cutting discs called burrs which will cut beans into even sized pieces and is a great investment for home brewing. In contrast, blade grinders use a spinning blade to chop the beans, creating inconsistent grounds full of dust (known as coffee fines) and boulders.
Hiroia Edge Ti Coffee Grinder
The Hiroia Starseeker EDGE Ti—Electric Burr Coffee Grinder is a fusion of power, precision, and elegance. Crafted with 48mm titanium-coated burrs, it delivers exceptional durability and cutting performance.
While scales are not necessary, if you want to perfect your pour over technique and brew consistent coffee to a set recipe then they are really helpful! We would be lost without our Jimmy Scales
Hiroia Jimmy Smart Scale
The Hiroia Jimmy Smart Scale is designed for both espresso lovers and pour-over perfectionists. Jimmy blends precision with personality, keeping every cup consistent without taking the joy out of the process.
A gooseneck kettle is a great addition to your manual pour over set-up. The spout allows you greater control as you carefully circle water around your dripper. Getting one that has a temperature control is brilliant to make sure that you are brewing at just the right heat.
The temperature of your water depends on the roast level of your beans as well as your preferred brew method. Lighter roasts are denser and less soluble than darker roasts and so can cope with higher brewing temperatures. Ideally use filtered water but avoid mineral water.
Roast level | Water temperature (°C) |
|---|---|
Light | 92-100 |
Medium | 85-95 |
Medium-dark | 80-90 |
Dark | 80-85 |
Blooming coffee is done by adding a small amount of water to your freshly ground coffee allowing the trapped CO₂ to escape. The process takes 30-45 seconds and you should use 2-3 times the weight of your coffee in water to do this. This CO₂ would otherwise interfere with the extraction process, limiting the contact between the coffee and the water. This is particularly important for pour over brews.
