There's a moment every home barista knows too well. You pull what feels like the perfect shot—the crema looks gorgeous, the flow seems right—and then you taste it. Sour. Again.
You adjust the grind. Too fine now. Bitter. You change the dose. Channeling. Three shots later, you've burned through $15 worth of beans and you're no closer to understanding what went wrong.
I lived in this cycle for months. And then I started writing things down.
The Humble Notebook Phase
My journey into espresso tracking started analog: a beaten-up Moleskine next to my machine, coffee-stained pages filled with scribbled numbers. Dose: 18g. Yield: 36g. Time: 28 seconds. Taste: "meh."
The problem? Notebooks are terrible for spotting patterns. Flipping through pages trying to remember what you did three weeks ago when that Ethiopian hit differently? Forget it. And good luck comparing your last ten shots at a glance.
But even this primitive tracking taught me something crucial: **consistency isn't just about technique—it's about information.**
The Revelation: Data Tells Stories Your Taste Buds Miss
Here's what changed when I got serious about tracking: I discovered I wasn't as consistent as I thought I was.
My "standard" 18g dose? Actually ranged from 17.4g to 18.8g depending on how rushed I was. My "usual" grind setting? I was adjusting it subconsciously based on vibes. My extraction times varied by 8+ seconds, and I'd been blaming the beans.
The data revealed an uncomfortable truth: I was introducing more variables than my coffee.
Once I locked in my process and tracked religiously, patterns emerged:
- That light roast I thought I hated? I'd been under-extracting it by 6 seconds consistently.
- My shots always ran fast on Monday mornings—turns out humidity changes over the weekend affected my grind.
- The "sweet spot" for my favourite blend wasn't 1:2 ratio. It was 1:2.3. I never would have found that without the data.
The Compound Effect of Small Adjustments
Improvement in espresso isn't about dramatic overhauls. It's about incremental refinements stacking over time.
When you track every shot, you can make **one** small change and actually see the result. Grind one notch finer. Does your average extraction time increase? Does your taste rating improve? You can answer these questions with evidence instead of guesswork.
This is the compound effect in action. A 1% improvement in dose consistency, plus a 1% improvement in distribution, plus dialling in your ratio precisely—suddenly you're pulling shots that taste like they came from your favourite café.
What I Track Now (And Why)
After a lot of experimentation, here's my tracking sweet spot:
**The Essentials:**
- **Dose** (in) — Your starting point. Consistency here affects everything.
- **Yield** (out) — This, combined with dose, gives you your ratio.
- **Time** — Extraction duration tells you about your grind and flow.
- **Taste rating** — The whole point. I use a simple 1-5 scale.
**The Context:**
- **Bean/roast** — Different beans need different approaches.
- **Grind setting** — So you can dial back in after switching beans.
- **Notes** — "Slightly sour," "perfect sweetness," "over-extracted on the back end."
The magic happens when you can filter and compare. Show me all my shots with Bean X above a 4-star rating—what did those have in common? That's where breakthroughs live.
Making Tracking Actually Stick
The reason most people abandon tracking is friction. If it takes 30 seconds to log a shot, you won't do it when you're half-awake at 6am.
That's exactly why I built Puck Yeah(https://www.puckyeah.app)—a shot tracking app designed specifically for home baristas who want the insights without the hassle. Quick logging, visual trends over time, and the ability to actually learn from your espresso history.
Because here's the thing: the best tracking system is the one you'll actually use.
The Unexpected Benefit: Patience
Tracking taught me something beyond technique. It taught me patience.
When a new bag of beans tastes off on day one, I don't panic anymore. I know from my data that most beans need 7-10 days post-roast to hit their stride with my setup. I've seen the pattern dozens of times.
When I switch grinders or change my basket, I give myself permission to have a few bad shots while I recalibrate. The data shows that's normal. The learning curve is real, and it's measurable.
There's a strange calm that comes from having evidence on your side.
our Journey Starts With Shot #1
You don't need to track perfectly. You don't need to obsess over every variable. You just need to start.
Log your next shot. And the one after that. Give it two weeks—maybe a bag of beans—and look back at what you've captured.
I promise you'll see something you didn't notice in the moment. A pattern. A variable you've been ignoring. A small adjustment that could change everything.
The path from "pretty good" to "genuinely excellent" espresso isn't about buying more gear. It's about understanding what's already happening in your cup.
And that understanding starts with data.
