About Coffee Brewing

The perfect cup of coffee depends on many factors including the coffee-to-water ratio, grind size, water temperature, and brewing time. Understanding how these variables interact helps you achieve your ideal flavour profile.

Coffee-to-Water Ratios Explained

Coffee-to-water ratio is expressed as 1:X, where X is how many parts water to 1 part coffee. Typical ratios include:

  • 1:12-1:13 - Strong coffee (often for espresso or concentrated methods)
  • 1:14-1:16 - Medium strength (balanced flavour, standard for most methods)
  • 1:17-1:18 - Lighter coffee (brighter, more delicate flavours)
Grind Size & Brewing Time

Grind size should match your brewing method and time:

  • Extra Fine/Fine - For espresso and Turkish coffee (short brew time)
  • Medium-Fine - For pour-over methods like V60 or AeroPress
  • Medium - For drip coffee makers
  • Medium-Coarse - For Chemex or clever dripper
  • Coarse - For French press or cold brew (longer brew time)
Water Temperature

The ideal water temperature for most coffee brewing methods is between 90-96°C (195-205°F). Using water that's too hot can lead to over-extraction and bitterness, while water that's too cool can lead to under-extraction and sourness.

Unleashing the Coffee Calculator

The Coffee Calculator is a handy tool for anyone who wants to brew the perfect cup of coffee. Whether you're a novice or a seasoned brewer, it helps you find the right coffee-to-water ratio for your preferred method. You can adjust factors like grind size, brewing time, and more to achieve your ideal flavour. It takes the guesswork out of brewing, making every cup consistent and delicious!

Selecting Your Brew Method

With the Coffee Calculator, you can choose from various brewing methods. Each method has its unique characteristics, which affect the taste and strength of your coffee. Here are some options you can select:

  • Pour Over
  • French Press
  • AeroPress
  • Drip Machine
  • Espresso
  • Cold Brew
  • Moka Pot
  • Chemex
  • V60
  • Custom

Custom Coffee-to-Water Ratios

If you have a specific preference for your coffee strength, you can enter a custom coffee-to-water ratio. The calculator allows you to set this ratio from 1:10 to 1:20, adjusting your brew to be stronger or lighter based on your taste. This feature is perfect for those who love experimenting with different flavours and intensities.

Measuring Coffee and Water

The calculator has two options for measuring your brew: by coffee amount or by water amount. You can specify how much coffee you want to use and let the calculator figure out how much water you need, or vice versa. This flexibility ensures you can brew exactly the amount you desire, whether it's for a single cup or a larger batch.

Key Brew Parameters for Perfect Coffee

When using the Coffee Calculator, you'll also set key brew parameters like grind size, water temperature, and brew time. These elements impact how your coffee tastes. For example, a finer grind suits shorter brewing times, while coarser grinds are best for longer methods. Knowing how to balance these factors helps you achieve your desired flavour profile.

Understanding the Brew Guidelines

The calculator doesn’t just give you numbers; it provides a brewing guide based on your chosen method. This guide includes details about the steps to follow, ensuring you can replicate the perfect brew every time. It’s a great feature for both beginners and experienced brewers looking for consistency in their coffee-making.

Visualising Your Brew Results

Another fantastic feature of the Coffee Calculator is the visual representation of your brew results. You'll see a chart that displays the ratio, coffee amount, water amount, and more. This visual guide helps you understand how adjustments can affect your coffee, making it easier to learn and experiment with different brewing techniques.

Learn and Grow as a Coffee Brewer

Finally, the Coffee Calculator includes a section on coffee brewing theory. This information covers coffee-to-water ratios, grind sizes, and ideal water temperatures. By understanding these concepts, you can improve your brewing skills and create a cup of coffee that's tailored to your tastes, making each brew a new adventure!
