A better place to start, built from the bag

Roast, process, elevation and origin each offer a clue about how a coffee may extract. Espresso Metrix combines all four into a practical starting temperature and brew ratio.

RoastMedium

The strongest signal for how readily the coffee may extract.

ProcessWashed

Adds context for body, clarity and fermentation-led flavors.

Elevation2,100 m

A useful clue about density when the bag provides it.

OriginEthiopia

A broad clue that supports the more specific details on the bag.

How it works

A repeatable dial-in workflow

Start from better information, change one thing at a time and keep what works.

1

Add your coffee

Save the bag details once, then keep every plan, result and adjustment attached to that coffee.

2

Start from a tailored baseline

Espresso Metrix suggests a starting temperature and ratio based on the coffee's roast, origin, process and elevation, so your first shot is an informed attempt.

3

Plan, pull, and log the shot

Set the target before brewing, then record what actually happened and how the cup tasted.

4

Mark it Dialed In & keep it

Save the shot that worked. As beans age, Quick Adjust Grind tracks small tweaks while your original dialed-in recipe stays untouched.

About Espresso Metrix

What is Espresso Metrix?
Espresso Metrix is an espresso dial-in log for home baristas. It keeps each coffee, planned recipe, actual shot, taste notes and dialed-in result together, so you can make the next adjustment with context and return to what worked.
How does Espresso Metrix help me dial in espresso?

Espresso Metrix keeps the variables that affect your espresso together: dose, yield, ratio, extraction time, temperature, grind setting, taste, and notes.

You can compare shots, identify what changed, plan your next adjustment, and save the recipe that produced your best result. Learn more →

What is a tailored espresso baseline?

When you add a coffee, Espresso Metrix suggests a starting temperature and ratio based on roast, origin, process and elevation.

The baseline does not replace dialing in. It gives the first shot a reasoned starting point, which you then adjust for your grinder, machine, water and palate. Learn more →

Can I use Espresso Metrix as an espresso shot tracker?

Yes. You can log the dose, yield, brew ratio, extraction time, temperature, grind setting, rating, taste characteristics, and notes for every shot.

Each shot remains connected to the coffee it was brewed with, making it easier to compare results throughout the life of the bag. Learn more →

Can I save espresso recipes for different coffee beans?
Yes. Every coffee has its own details, shot history, and dialed-in recipe. You can save the result that worked best and return to it whenever you brew that coffee again.
Can I plan my next espresso shot before brewing it?

Yes. You can create a target recipe before pulling the shot, including the dose, yield, ratio, temperature, grind setting, and expected extraction time.

After brewing, you can turn the plan into an actual shot log and record what happened in the cup.

Does Espresso Metrix tell me how to adjust my espresso?

Espresso Metrix gives you a structured record of the recipe, result and taste so you can choose the next adjustment with better evidence.

It does not prescribe one correct recipe. Grinder, machine, basket, water, coffee age and personal taste all shape the result.

Can I track how espresso changes as the beans age?

Yes. Espresso Metrix lets you make day-to-day grind adjustments while preserving your original dialed-in recipe.

This helps you compensate for changes in the coffee as it ages without losing the reference recipe that initially worked. Learn more →

What coffee information can I save?

You can save information including the roaster, coffee name, origin, roast level, roast date, processing method, elevation, photos, and personal notes.

You can then keep every planned recipe and completed shot connected to that coffee.

What does “Now Brewing” mean?
Now Brewing is a dedicated place for the coffees you are actively using. It keeps their current recipe, grind adjustment, and recent extraction information easy to reach without searching through your full espresso diary.
Is Espresso Metrix suitable for experienced home baristas?

Yes. Espresso Metrix is built for home baristas who already know the dial-in loop and want a cleaner record of each decision.

It supports your workflow without imposing a brewing method or deciding what a good espresso should taste like.

Do I need a specific espresso machine or grinder?

No. Espresso Metrix can be used with any espresso machine or grinder.

You can choose your preferred grinder notation, measurement units, temperature unit, pressure unit, dose increments, and other settings to match your equipment.

Does Espresso Metrix support different grinder settings?
Yes. You can configure how grind settings are recorded to better match your grinder, including decimal, click-based, alphanumeric, hundredths, tenths, or manual formats.
Is Espresso Metrix free?

Espresso Metrix can be used free with no time limit. The free version lets you save up to two coffees and six shot logs for each coffee, including iCloud sync.

Premium removes the coffee and shot-log limits. Download free →

Does the free version expire?

No. The free version has no trial deadline and does not stop working after a set number of days.

You can continue using it within the free coffee and shot-log limits for as long as you choose.

Do I need to create an account?

No. Espresso Metrix does not require an Espresso Metrix account, email address, or password.

Your espresso diary is stored on your device and can sync through your personal iCloud account.

Where is my espresso data stored?

Your coffee and shot data is stored on your Apple devices and synced through your personal iCloud when iCloud is available.

Espresso Metrix does not operate developer servers that store your espresso diary.

Does Espresso Metrix collect or sell my coffee data?

Espresso Metrix does not use advertising or tracking and does not sell your espresso diary data.

For complete details about data handling, read the Espresso Metrix Privacy Policy.

Can I use Espresso Metrix without iCloud?
Yes. You can record and manage your espresso diary on your device. iCloud keeps supported data synced between your Apple devices when it is enabled and available.
Which devices support Espresso Metrix?
Espresso Metrix is currently available for iPhone through the Apple App Store.
Is Espresso Metrix available for Android?
No. Espresso Metrix is currently an iPhone app and is not available for Android.
Is Espresso Metrix only for straight espresso?

Espresso Metrix records espresso extraction and taste data, so you can use it for shots served straight or used in drinks such as cappuccinos, flat whites, and iced espresso drinks.

Its primary purpose is to help you understand and reproduce the underlying espresso shot.

Espresso brewing questions

How do I dial in espresso for a new bag of beans?
Keep dose stable, choose a sensible starting ratio and use taste with flow and shot time to decide the next move. Espresso Metrix can suggest a starting temperature and ratio from the coffee's roast, origin, process and elevation. Learn more →
What is the best espresso ratio for a double shot?
A 1:2 brew ratio (18g of ground coffee to 36g of espresso) is the standard starting point. Lighter roasts often shine at 1:2.2–1:2.5, darker roasts at 1:1.8–1:2. Learn more →
Why does my espresso taste sour?
Sharp sourness with little sweetness often points to under-extraction, especially when the shot also ran fast. Try a slightly finer grind while keeping the other controls stable. If sourness and bitterness appear together, check for channeling first. Learn more →
Why does my espresso taste bitter?
Harsh bitterness and a drying finish often point to over-extraction, particularly when the shot ran slowly. Try a slightly coarser grind or a shorter yield, one deliberate change at a time. Roast character and dirty equipment can also add bitterness. Learn more →
How long should an espresso shot take?
25–35 seconds for a double shot at a 1:2 ratio is the classic window, but time is a diagnostic, not a target. Taste decides. Learn more →
Should I adjust grind size as coffee beans age?
Often. As beans degas, the same recipe may begin to run faster, so a small finer adjustment can restore the flow you had when the coffee was dialed in. Quick Adjust Grind tracks the current setting without overwriting the original recipe. Learn more →
