Coffee Tasting Notes iPhone App: Log Specialty Brews Before the Cup Goes Cold

Capture specialty coffee tasting notes by voice while you brew — roast, origin, flavor, and parameters. Build a personal coffee database with Nemos on iPhone.

·By Taha Baalla

The specialty coffee community has a documentation problem. Tasters buy a complex single-origin, experience interesting cup profiles across multiple brews, then move on and can't remember whether the Kenya or the Ethiopia tasted better with their V60 at 93°C.

A consistent tasting note practice solves this. You build a personal reference over time, develop vocabulary precision, and make better purchase decisions — all from 60-second captures at your brewing station.

What to Capture in a Coffee Tasting Note

The bean data: Roaster, origin (country and region), process (washed, natural, honey), variety (Bourbon, Gesha, SL28, etc.), roast level (light/medium/dark), and roast date. This data is on the bag — capture it before you brew the first cup.

Brew parameters: Method (pour-over, AeroPress, espresso, French press), grind size (coarse, medium-fine, etc.), water temperature, brew time, and ratio (grams coffee to grams water).

Tasting impressions: Aroma (dry grounds, wet grounds, in-cup), flavor (what you taste across the cup — acidity, sweetness, bitterness, body), and aftertaste. Use simple sensory language: "bright citrus, slight chocolate, tea-like body."

Assessment: Your personal rating. Does this bean suit this method? Would you buy it again?

The Voice Note Workflow at the Brew Station

Most home coffee brewers have their hands occupied during brewing — grinding, pouring, timing. Voice notes fit naturally into the workflow gaps.

Before brewing: Speak the bean data while the kettle heats. "Onyx Coffee, Ethiopia Guji, natural process, light roast, roast date April 20th. Brewing V60 today, 93°C, 15g coffee to 250g water."

Dry aroma: After grinding, speak the ground aroma: "Ground: intensely floral, jasmine and bergamot."

Wet aroma: During bloom phase: "Wet: lemon curd, brown sugar, very aromatic."

Cup tasting: As the coffee cools through different temperatures (most specialty coffee is designed to be tasted across a temperature range): "Hot: bright, acidic, citrus peel. Warm: sweet, tangerine, caramel developing. Cool: complex, floral, very long finish."

Rating and notes: "8/10. One of the best naturals I've had this year. Try at 91°C next time. Would buy again."

Total time: under 3 minutes, spread across the brewing session.

The Brew Log: Parameters + Notes Together

Combine tasting notes with brew parameter logging. When you find a cup that's exceptional, you want to reproduce it. When a cup is flat or astringent, you need to diagnose why.

Create a note format: - [Date] [Roaster] [Origin] — [Method] - Parameters: [ratio, temperature, time, grind] - Notes: [aroma, flavor, rating] - Next brew: [what to adjust]

This creates a feedback loop. Over 10 brews of the same bean, you dial in the optimal parameters for your equipment.

Specialty Coffee Vocabulary Primer

You don't need to match the SCAA flavor wheel vocabulary exactly. But consistent personal vocabulary helps:

Acidity types: Bright (citric, like lemon), malic (like green apple), phosphoric (like grapes), or flat/absent.

Sweetness: Caramel, brown sugar, honey, fruit-sweet, syrupy.

Body: Tea-like (thin), medium, full, heavy, syrupy.

Flavor notes: Use fruit analogies (orange, strawberry, blueberry), chocolate ranges (dark, milk, cocoa powder), herbal (jasmine, bergamot, black tea), and nutty (almond, hazelnut).

Speak in comparisons that mean something to you: "This tastes like the orange juice my grandmother made" is a more precise sensory reference for you than "citrus" floating free of context.

Tracking Across Roasters

As you try more roasters, your Nemos collection becomes a comparative database. Before buying from a new roaster, search your notes for previous orders. Pattern recognition emerges:

  • Do you prefer Kenyan coffees across all roasters? You likely have high malic acid sensitivity.
  • Does your notes consistently rate naturals lower? You may prefer clean washed coffees.
  • Which roasters consistently produce beans that suit your preferred brew method?

This takes 30–50 tasting notes to become useful. Start now.

Espresso vs. Filter: Log Separately

The same bean brewed as espresso and filter produces dramatically different cup profiles. Log them as separate notes. A bean that's excellent as a V60 may be harsh as espresso and vice versa.

When noting espresso, include: shot time, yield ratio, and machine pressure if relevant. "25 seconds, 1:2.3 ratio, La Marzocco, medium-fine grind, 9 bar."

Cafe Notes vs. Home Brew Notes

When you have an exceptional cup at a cafe, capture the details before you leave the table: cafe name, barista if you know them, bean and origin if listed on the menu board, brew method and cup size, your impressions.

This helps you remember which cafes to revisit, which roasters to seek out, and context for flavors you want to explore at home.

Using iPhone Accessibility Features at the Brew Station

Coffee brewing often involves both hands. iPhone Back Tap (Settings → Accessibility → Touch → Back Tap) lets you open Nemos with two taps on the phone back while both hands are on the kettle or portafilter.

Alternatively: Siri. "Hey Siri, open Nemos" — hands-free app launch when your hands are literally wet or occupied.

Coffee Tasting Notes and Community

The specialty coffee community shares tasting notes publicly on platforms like Coffeebook, Beanconqueror, and roaster-specific Discord servers. If you want to share notes, Nemos captures your raw impressions, which you can expand into a public-facing format later.

The community norm is honest, personal impressions over technically perfect vocabulary. Your note "tropical fruit, like mango candy, very sweet" is more useful to someone buying the same bean than a technically accurate but vague "complex fruited profile."

FAQ

How soon should I taste coffee after roasting? Most specialty roasters recommend a 7–14 day rest period after roast date before brewing. Very fresh roasts off-gas CO2 aggressively, which suppresses flavor expression. Note the roast date and tasting date in your notes — it affects your impressions.

Should I taste every cup or just notable ones? Personal choice. Some coffee enthusiasts log every bag; others only log exceptional or memorable cups. Starting with "log bags I want to remember or buy again" is a reasonable default.

How do I handle coffee I've tasted but forgotten? Retroactive notes are worth making even from memory. "This was a natural Ethiopian from a local roaster, very sweet, bought again" is better than no record.

Is Nemos better than dedicated coffee apps like Beanconqueror? Dedicated apps offer structured data fields (origin, variety, process) and community features. Nemos is better for free-form sensory notes and voice capture during brewing. Some enthusiasts use both: structured data in a dedicated app, sensory impressions in Nemos.

Can I track espresso dial-in notes too? Yes. Create a "Dial-In" note per bean and log each shot attempt with parameters and result. "Shot 3: too sour, too short at 22s, grind finer" — this tracks your progression to a dialed shot.
