How to Keep a Coffee Tasting Journal (Free Brew Log)
Updated
A coffee tasting journal in 4 lines: beans, dose, grind, one taste word. Free brew log template and how to use it to dial in.
Great cup Monday, meh cup Tuesday, same beans. Sound familiar? Something changed: the grind, the dose, the water. You just do not remember what. A coffee tasting journal is the simplest fix there is. It is not fancy and it is not homework. It is a few lines that turn guessing into learning, so you can repeat your best cup on purpose.
This guide shows you exactly what to write down, gives you a free brew log template you can copy, and walks through how to use your notes to dial in.
Why Write Down Your Coffee?
Coffee has a handful of variables, and small changes add up. When a cup tastes great, you want to know why. When it tastes off, you want to know what to change. Memory is not reliable at 6 a.m. A short note is.
The goal is not to become a coffee scientist. It is to spot patterns: this bean likes a slightly finer grind, that roast tastes better a touch cooler, and so on. A week of notes and you will start to know your perfect cup by heart.
The 4 Lines That Matter
You only need four things. Scrap paper works fine.
- Beans + roast date — what you brewed, and how fresh it is
- Dose + water — grams of coffee and grams of water, if you can weigh them
- Grind setting — the number or click on your grinder
- One taste word — sour, bitter, flat, great, or whatever fits
That is it. If you want to add more later (brew time, water temperature, method), go for it. But four lines you actually write beat ten lines you skip.
Weighing your dose and water makes your notes far more useful, because “two scoops” is not the same every morning. A simple scale like the Greater Goods Coffee Scale gives you 0.1 g precision and a built-in timer at a friendly price.

Copy this table into a notebook, a notes app, or a spreadsheet. One row per brew.
| Date | Beans + roast date | Dose + water | Grind setting | Taste word | What I changed |
|---|---|---|---|---|---|
Example entries (for illustration only)
These are made-up examples to show how a log might look over a few mornings. Your beans, grinder numbers, and results will be different.
| Day | Beans + roast date | Dose + water | Grind setting | Taste word | What I changed |
|---|---|---|---|---|---|
| Example 1 | Medium roast, roasted last week | 15 g / 250 g | Setting 16 | Sour | Starting point |
| Example 2 | Same beans | 15 g / 250 g | Setting 14 | Better, a little thin | Grind finer |
| Example 3 | Same beans | 16 g / 250 g | Setting 14 | Great | A bit more coffee |
Notice that each example changes only one thing from the day before. That is the whole trick.
A Simple Taste-Word List
You do not need fancy tasting notes. One honest word is enough. Here are some easy ones to start with:
- Sour — sharp, tangy, a bit like under-ripe fruit
- Bitter — harsh or lingering, drying on the tongue
- Flat — dull, not much flavor either way
- Thin — watery, light body
- Heavy — thick, a little muddy
- Sweet — rounded and pleasant
- Balanced — nothing sticks out in a bad way
- Great — you would happily brew it exactly this way again
Over time you may start noticing things like chocolatey, nutty, or fruity. Add them when they come naturally.
How to Use Your Journal to Dial In
The rule is simple: change one thing at a time, then note it. If you change the grind and the dose on the same morning, you will not know which one made the difference.
- Tastes sour or thin? Try a slightly finer grind or a touch hotter water.
- Tastes bitter or harsh? Try a slightly coarser grind or a touch cooler water.
- Tastes flat or weak? Check your ratio and how fresh your beans are.
Grind size is usually the most powerful lever, so it is a good first thing to adjust. For more detail, see Why Coffee Tastes Bitter or Sour, the Coffee Grind Size Chart, Coffee to Water Ratio, and Best Water Temperature for Coffee.
When you hit a cup you love, circle that row. That is your recipe for those beans. When you open a new bag, start from your best settings and adjust from there.
Frequently Asked Questions
What should I write in a coffee tasting journal?
Start with four things: beans and roast date, dose and water, grind setting, and one taste word. Add more only if it helps.
Do I need a scale?
It is not required, but weighing dose and water makes your notes much more reliable than scoops.
How long until I see a difference?
Many people start noticing patterns after about a week of notes, especially if they change only one thing at a time.
