To compare Meraki espresso with the coffee you made before an upgrade, use the same batch of beans, keep the tasting conditions similar, and give both setups a chance to produce a well-dialed-in shot. Start with a familiar brew ratio, then compare sweetness, acidity, body, and finish. Repeat the comparison before deciding whether a difference comes from the equipment or an unusually good or poor shot.
Your usual beans give you a useful reference. You already know what you enjoy about them: perhaps a chocolate-like finish, gentle fruitiness, or enough presence to hold their own in milk. The question is whether the new setup brings you closer to that taste—and how reliably you can make it again.
Why Start With the Coffee You Already Drink?
Opening a new bag from a different roaster on the day you change machines introduces two changes at once. If the espresso tastes brighter, heavier, or more bitter, it becomes harder to identify why.
Use beans from the same bag or roast batch where possible. Matching the blend name alone is less useful if one bag has been open for weeks and the other was roasted recently. Record the roast date, opening date, and how the coffee has been stored.
The Specialty Coffee Association’s discussion of coffee freshness and storage explains how time, oxygen, moisture, and temperature affect roasted coffee. For a home comparison, the practical point is simple: keep both portions together under the same storage conditions until you need them.
If the beans are still changing quickly after roasting, allow for that when interpreting the results. Understanding how long coffee beans should rest before espresso can help you choose a more useful comparison window.
Decide What You Are Comparing
Before brewing, decide whether you want to compare a familiar recipe or the best result you can reasonably achieve on each setup. Both are useful, but they answer different questions.
| Comparison | What to do | What it tells you |
|---|---|---|
| Familiar-recipe comparison | Use a suitable dose and your existing brew ratio as starting points. Dial in each grinder rather than copying settings. | How a similar recipe tastes on the new setup. |
| Preferred-result comparison | Allow each setup its own grind and recipe, then compare the shots you prefer from each. | Which result better suits your taste after adjustment. |
Begin with the familiar-recipe comparison, then move to the preferred-result comparison if needed. Avoid comparing months of practice on your old machine with the first unadjusted shot from your Meraki coffee machine.
If you replace both the grinder and espresso machine, describe the result as a comparison between complete setups. The grinder, basket, and brewing conditions can all contribute to a flavor change. The cups alone cannot isolate which component caused it.
Make the First Comparison Fair
You do not need a laboratory, but a few consistent choices will make your tasting more useful.
- Beans: use the same roast batch and grind each portion shortly before brewing.
- Water: use the same water if it meets both machines’ requirements. Record any necessary difference.
- Readiness: prepare and warm up each machine according to its instructions, including the portafilter.
- Basket dose: use an appropriate amount for each basket rather than forcing an identical dose.
- Brew ratio: keep the initial dose-to-yield ratio similar and weigh the finished espresso.
- Cups: use matching cups with the same preheating routine.
- Preparation: keep distribution, tamping, and puck-screen use consistent within each setup.
For example, 18 g of coffee producing 36 g of espresso gives a 1:2 ratio. If a different basket calls for 17 g, a 34 g yield preserves that ratio. These are illustrative numbers, not prescribed settings for Meraki. The relationship between espresso dose and basket capacity matters more than matching a number that does not fit.
Matching the ratio does not guarantee matching concentration or extraction. It simply provides a clear starting point. Keep the actual dose and beverage weight in your notes so you can interpret any difference.
Use Meraki’s Measurements to Keep Track of the Recipe
The Meraki espresso machine includes a built-in grinder, separate scales for coffee dose and espresso yield, and automatic stopping at a target yield. These functions help you record and repeat the recipe while assessing flavor.
Choose a dose appropriate for the basket, set your initial yield, and record the final amount in the cup. Use the grinder instructions supplied with your machine to establish a suitable grind. An old grinder’s dial number is not a transferable recipe setting.
For the first comparison, keep dose and yield steady while making the necessary grind adjustments. If you later change the recipe to suit your taste, record the new espresso dose-to-yield ratio instead of trying to preserve the old one at all costs.
The measurements help explain what you brewed. They do not replace tasting or guarantee that two shots with matching numbers will taste alike.
Taste at Similar Temperatures
A freshly pulled espresso and a cup that has been sitting for several minutes are difficult to compare fairly. Brew the samples as close together as practical, stir each one, and taste when both are comfortably warm and at similar temperatures.
A study on beverage temperature and consumer preferences for black coffee examined how tasting temperature relates to coffee acceptance. It studied drip coffee, so it does not establish an ideal espresso tasting temperature. It does reinforce the importance of distinguishing the temperature at which coffee is brewed from the temperature at which you taste it.
If one person is operating both machines, note which shot was brewed first. Reverse the brewing order in a later comparison so the same setup is not always represented by the older cup.
Take a small sip from each, pause, and return to them as they cool. Use plain water between samples. There is no need to finish every shot to make useful notes.
Hide the Machine Names When You Can
If someone can help, ask them to label the cups A and B without telling you which is which. Write your observations and preference before revealing the labels.
This is a simple way to reduce the influence of expectations about the new machine. It is an informal home comparison, not a professional sensory test, but it encourages you to describe the coffee before judging the equipment.
Describe the Difference Before Calling It Better
“Stronger” can mean several things: more concentrated, more bitter, heavier in texture, or simply more noticeable in milk. Use a few specific observations instead.
The World Coffee Research Sensory Lexicon provides a structured vocabulary for describing coffee attributes. You do not need its full terminology for this comparison. Familiar words such as cocoa, toasted nuts, citrus, drying, or smooth are useful when they describe what you actually notice.
| Attribute | What to ask | Example note |
|---|---|---|
| Perceived sweetness | Does the cup have a pleasant sweet impression, or is it overshadowed by sharpness or bitterness? | More caramel-like, with less bitter interference. |
| Acidity | Is it gentle, lively, sharp, or out of balance? | Clear citrus character that I enjoy. |
| Bitterness | Does it support the flavor or dominate the cup? | Cocoa-like at first, then too bitter in the finish. |
| Body | Does the espresso feel light, rounded, heavy, or thin? | Lighter texture, but not watery. |
| Finish | What remains after swallowing, and is it pleasant? | Lingering chocolate without a drying sensation. |
| Preference | Which cup would you choose to drink again? | I prefer B because its acidity feels more balanced. |
Keep description separate from preference. A fuller body is a difference; whether you prefer it is another question. Likewise, acidity is not automatically a fault, and a larger layer of crema does not settle which espresso tastes better.
Compare the Drink You Actually Make Every Day
If your usual coffee is a latte or flat white, include that drink in the comparison. An espresso you prefer on its own may not be your favorite once milk is added.
First taste the espresso by itself so you have a reference. Then prepare comparable milk drinks using:
- The same type and brand of milk.
- The same measured amount of milk added to each drink.
- Similar milk temperature and foam texture.
- Matching cups.
Ask whether the coffee remains clear in the drink, whether bitterness dominates, and whether the balance suits your routine. Avoid adding extra milk to only one sample unless you are deliberately testing each setup’s preferred finished recipe.
If you steam the milk on different machines, differences in texture and temperature become part of the finished-drink comparison. Record them separately rather than attributing every change to espresso extraction.
Repeat the Comparison Before Drawing a Conclusion
One excellent shot does not establish consistency, and one disappointing shot does not define a machine. Repeat the comparison after both setups are dialed in. A few paired tastings can reveal whether your preference holds, although they are not enough to establish a universal performance claim.
Keep a short record:
| Record | Sample A | Sample B |
|---|---|---|
| Dose / final yield | ||
| Time / timing method | ||
| Flavor and texture | ||
| What I liked or disliked | ||
| Preference and reason |
Also note how much adjustment each setup needed and whether you could repeat the result the next day. Keep those workflow observations separate from the flavor notes: a more convenient routine is valuable, but it is a different benefit from a sweeter-tasting cup.
What If You No Longer Have the Old Machine?
Use your previous recipe notes as a reference, but treat the exercise as establishing a new baseline rather than a direct comparison. Flavor memory cannot recreate a missing sample.
Write down what you want from your usual beans: a rounded body, a softer finish, clearer fruit, or enough coffee character in your morning latte. Then assess whether your Meraki espresso delivers those qualities consistently.
You can still make a useful judgment about the new setup without claiming that it has outperformed a cup you cannot taste alongside it.
Common Questions About Comparing Espresso After an Upgrade
Should both machines use exactly the same grind setting?
No. Different grinders use different adjustment scales and can produce different grounds at apparently similar settings. Dial in each setup separately. Even when using one grinder for both machines, the baskets may require different settings.
Does a longer shot time mean better extraction?
Not by itself. Record time using the same starting event, but assess it alongside dose, yield, flow, and taste. A longer shot is not automatically sweeter or more balanced.
What if I prefer the old machine’s espresso at first?
Check that the new setup has been dialed in and that the comparison uses similar beans, water, and tasting conditions. Then adjust one variable at a time. If you still prefer the old result, that is a useful preference to record rather than something the comparison needs to explain away.
Should I buy different beans for Meraki?
Begin with familiar beans that meet the grinder’s usage guidance. Once you have a repeatable recipe, trying another coffee becomes a separate experiment. You do not need to change beans simply because you have changed machines.
A useful before-and-after comparison leaves you with more than a winning cup. It tells you what changed, which differences you enjoy, and how to repeat the result with the coffee you already like.
