Coffee Calculator Collection

A suite of coffee calculators for baristas

Extraction calculators

Use these calculators to determine your Extraction Yield %, a measure of how much coffee solubles you extracted as a percentage of your dose. There is one for espresso and filter coffee.

Recipe design calculators

tap for more info

Use these calculators to help you design the best coffee recipe for a chosen brewing device. All you need to do is tell them how much coffee you want to make.

Strength calculators

Use these calculators to help you calculate the strength of your milk drinks or even how to dilute your coffees that are too strong by the addition of water post brewing.

DIY Water for Coffee Calculators

This super calculator allows you to calculate everything from stock concentrates through to dilution and titrations to create the perfect brewing water from scratch.

This collection of coffee calculators is designed for past students who have completed our Advanced Barista or 5 Day Master Barista Courses to help fine-tune coffee extractions.

These coffee calculators have been made available free for everyone to use and access, past student or not, so if you understand what Extraction Yield %, TDS %, and Liquid Retained Ratio mean, these calculators are for you.

You will need a coffee/espresso refractometer to use these calculators to measure your brew’s TDS % to get any meaningful results or insight into your extractions.

I hope you find these tools useful in your quest for delicious tasting coffee!

Use this calculator to calculate how extracted your espresso is.

Use this calculator to calculate how extracted your filter coffee is.

 

Select your mode; either pour over or total immersion:

  • Pour over methods include: Hario V60, Kalita Wave, Chemex etc
  • Total immersion methods include: French press/plunger, Aeropress, Syphon etc.

Calculations for extraction % are different depending on your coffee brewer type.

Use this calculator to determine your LRR a.k.a. WAF, a measurement of how much water was absorbed by the coffee grinds during brewing

Use this calculator to design recipes for espresso.

 

Given a target:

  • Dose
  • Strength / TDS %
  • Extraction %

The calculator will tell you how much espresso you need in your cups (yield) to hit those targets.

Use this calculator to design recipes for espresso.

 

Given a target:

  • Yield
  • Strength / TDS
  • Extraction %

The calculator will tell you how much coffee to dose into your filter basket to hit those targets.

Use this calculator to design recipes for pour overs and French presses.

 

You decide:

  • How many people you’re serving
  • How much brewed coffee per person
  • Intensity of flavour

The calculator will tell you how much ground coffee and hot water to use to make enough coffee at your desired strength.

Use this calculator to create recipes for auto-drip coffee makers or batch brewers.

 

Tell it how much coffee you want to brew and it will tell you:

  • how much ground coffee to use
  • how much cold water to use

If you know your brewer's water reservoir capacity, it will tell you:

  • how much ground coffee to use
  • how much brewed coffee will be brewed

Use this dilution calculator if you want to know:

  • How much water to add a coffee to achieve a desired diluted strength
  • How strong your coffee is after adding a known amount of water

This calculator is useful for designing long black/americano recipes or fixing (diluting) a brew of coffee that is too strong.

Use this milk coffee calculator to help you understand the effects of milk foam depth and cup volume on your coffee's concentration and flavour.

This collection of coffee water calculators was inspired by the groundbreaking book, Water for Coffee, by World Barista Championship finalist, Maxwell Colonna-Dashwood and computational chemist, Christopher Hendon.

 

Use these calculators to help you design custom brewing water from scratch.
