La Taza Habla

Part 3: Training to Taste - Organic Acids

In this episode of La Taza Habla, we dive deep into the sensory science of specialty coffee to demystify the complex world of organic acids. Drawing on over two decades of experience and the high-stakes pressure of a Q Grade exam, we explore a unique musical framework for understanding flavor. By comparing the four primary acids—citric, malic, acetic, and quinic—to the instruments in a blues band, you’ll learn to identify the sharp "lead guitar" brightness of lemon and the "harmonica" roundness of green apple.

We move beyond technical jargon to provide a practical exercise on how organic acids affect what you taste. Whether you are a home brewer or a professional, this episode includes a step-by-step DIY palate training guide using simple kitchen ingredients like lemon juice and over-steeped tea. Discover how to "listen" to the flavors in your cup and understand the rhythm of your morning ritual.

5 Takeaways

1. The Musical Metaphor: Use a blues band framework to categorize flavors: Citric (Lead), Malic (Harp), Acetic (Drums), and Quinic (Bass).
2. Temperature Reveals Truth: As coffee cools, the sharp citric notes settle, allowing the rounder, malic flavors (green apple) to step forward.
3. Feeling vs. Tasting: Acetic acid is felt as a "sparkle" or "zing," while Quinic acid provides the physical "weight" or body you feel in your chest.
4. The Danger of Over-Fermentation: Too much acetic acid transforms a "groove" into a vinegar-like taste, often due to bad fermentation.
5. Training is Accessible: You don't need a professional cupping lab; you can train your palate using diluted lemon juice, apple juice, vinegar, and tea.

Show Notes

🍋 Citric Acid Recipe

• Preparation: Dilute fresh lemon juice 1:125 to 1:150 with water, or dissolve 4g food-grade citric acid powder in 1L water
• Taste: Sharp, clean sourness — hits the sides and front of your tongue with immediate onset and fades quickly (~5–10 seconds)

🍏 Malic Acid Recipe

• Preparation: Fresh green apple juice, diluted 1:1 if very tart. Alternative: dilute apple cider vinegar 1:10
• Taste: Slower onset than citric, persistent finish, subtle sweetness woven in — a "juicy" mouthfeel that lingers instead of fading

🫙 Acetic Acid Recipe

• Preparation: Three concentrations to build your range:
  • Sub-threshold: 1 tsp white vinegar in 2 cups water (~0.1%)
  • Threshold: 1 tsp in 1 cup water (~0.4%)
  • Above threshold: 2 tsp in 1 cup water (~0.8%)
• Taste: Pungent sharpness with slight burning or irritation — you'll feel it in your nose as much as your tongue. Taste all three side by side to map how sharpness scales.

🍵 Quinic Acid Recipe

• Preparation: Steep 2 tbsp black tea in 1 cup boiling water for 5+ minutes (over-steep intentionally). Alternative: tonic water, diluted 1:1 if too sweet
• Taste: Drying, puckering mouthfeel — reduced saliva sensation, bitterness without sourness. This is a feeling more than a flavor.

Part 2: Training to Taste - Aroma Perception

In this episode of La Taza Habla, we explore the often-overlooked world of specialty coffee sensory training. Much like a pilot must be trained to fly, a coffee lover must be trained to truly taste. We break down the complex sensory training journey through a unique baseball analogy, explaining how your olfactory bulb processes hundreds of signals simultaneously—just like a player navigating the bases.

Moving beyond basic "coffee roasting" flavors, we dive into the codified science of aroma perception. You will learn a practical "base running" drill to help you identify flavor families, starting with the broad category of fruit and narrowing it down to specific notes like citrus, raisins, or plum. Whether you are a novice or a seasoned professional, this episode provides the tools to move from "first base" to "home plate" in your sensory journey. We also discuss how your perception might shift as the cup cools, reminding us that what we smell at the start isn't always the finish.

5 Takeaways

1. Training is a Requirement: Just as pilots require training to fly, the ability to perceive complex coffee flavors is a learned skill, not just an intuition.
2. The Nose is a Powerhouse: While your eyes use only three receptors to see every color, your olfactory bulb uses over 300 to process the dozens of signals in every sip.
3. Use a Sensory Vessel: To properly "trap" aromatics, use a small wine glass, snifter, or a mason jar with a lid to concentrate the scent for 30 seconds before smelling.
4. Establish a Baseline: Use common household items, like a jar of mixed fruit jelly, to create a "baseline" for broad flavor families before trying to identify specific notes.
5. Track the Temperature: Always re-evaluate your coffee as it cools; the flavor notes you detect at 180°F may be entirely different once the cup reaches room temperature.

🧪 DIY Aroma Reference Kit — From the World Coffee Research Sensory Lexicon

How to use: Place each reference in a small wine glass or snifter. Cover with a lid or coaster to trap the aromatics. Let it sit for 30 seconds. Lift and smell. Then brew a cup of coffee and see if you can find that same aroma in the cup.

---

☕ Family 1 — Fruit

Step 1 — Broad family: Fruity

Smucker's mixed fruit jelly — open the jar and smell. A sweet, bright, generalized fruit aroma. That's your baseline before you break it apart.

Step 2 — Narrow the fork: Citrus or dried fruit?

Fresh lemon (cut) next to a plum. Lemon is bright and electric. Plum is dark and heavy. Two completely different directions.

Step 3 — Name it

Line up a lemon, an orange, and a grapefruit. The differences are obvious when isolated — that's the whole point of training.

---

🌸 Family 2 — Floral

Step 1 — Broad family: Floral

Uncooked jasmine rice in a bowl — cover and let it sit. A delicate, perfumed sweetness. This is what floral smells like before you get specific.

Step 2 — Narrow the fork: Jasmine or rose?

Jasmine rice next to a capful of rose water. Jasmine is light and airy. Rose is heavier, almost syrupy. One floats, the other lingers.

Step 3 — Name it

Steep a chamomile tea bag and smell alongside the jasmine and rose. Chamomile adds an herbal-sweet third option — honeyed, dry, and earthy.

---

🥜 Family 3 — Nutty/Cocoa

Step 1 — Broad family: Nutty

A spoonful of Jif creamy peanut butter on a plate. Rich, oily, roasted — the broadest expression of "nutty" most people already know.

Step 2 — Narrow the fork: Nut or chocolate?

Raw almonds next to Hershey's Natural Unsweetened Cocoa Powder mixed with a splash of water. Almonds are dry and clean. Cocoa is deep and bitter. Same family, opposite directions.

Step 3 — Name it

Line up a raw almond, a hazelnut, and the cocoa paste. Almond is mild and papery. Hazelnut is richer and sweeter. Cocoa is dark and heavy. Three distinct markers.

---

🔥 Family 4 — Roasted

Step 1 — Broad family: Roasted

A handful of Grape-Nuts cereal in a bowl. Toasty, grain-forward, malty — roasted before it gets dark.

Step 2 — Narrow the fork: Toasted grain or burnt?

Grape-Nuts next to a piece of heavily charred toast. Grain is warm and sweet. Burnt is acrid and sharp. The fork between medium and dark roast character.

Step 3 — Name it

Line up the Grape-Nuts, the burnt toast, and a drop of Wright's liquid smoke on a cotton ball. Malt, carbon, and smoke — three distinct stops on the roast spectrum.

---

🌿 Family 5 — Green/Vegetative

Step 1 — Broad family: Green

A fresh green bell pepper — cut it open and smell the inside. Vegetal, raw, alive — this is the green family at its broadest.

Step 2 — Narrow the fork: Fresh herb or underdeveloped roast?

Fresh basil leaf next to 25g chopped flat-leaf parsley steeped in 300g of water. Basil is bright and aromatic. Parsley water is flat and grassy — your forensic tool for spotting underdevelopment.

Step 3 — Name it

Line up the bell pepper, the basil, and the parsley water. Pepper is raw and sharp. Basil is aromatic and sweet. Parsley water is dull and green. If your coffee smells like that last one, the roaster didn't finish the job.

Part 1: Training to Taste - The Five Basic Tastes

In this episode of La Taza Habla, we pull back the curtain on why so many specialty coffee lovers feel lost despite years of "education." Drawing on two decades of experience and Q Grader training, we explore the disconnect between the industry's branding and the actual experience of coffee tasting. We dive into why terms like acidity in coffee remain confusing for the average drinker and how "Big Coffee" handed us a map without teaching us how to read it.

This isn't just about coffee roasting or origin—it’s about reclaiming your own palate. We move beyond the "training room" labels and return to the "tasting room" reality. You’ll learn a simple, DIY palate training exercise using common pantry items to recalibrate your tongue to the five basic tastes: sweet, sour, salty, bitter, and savory . By the end of this episode, you’ll have a foundational sensory lexicon that doesn't rely on a bag's marketing, but on your own biological flavor attributes. Stop trading tasting for talking and start trusting what is actually in your cup.

5 Takeaways

1. Biological Foundations: You already possess the biology to detect sweetness, bitterness, and acidity; you don't need a certificate to own your taste.
2. Language as a Barrier: Industry frameworks often act as a "layer" between the drinker and the cup, prioritizing labeling over the actual experience of tasting.
3. The "Map" vs. The "Dictionary": The industry provided the vocabulary (the map) but kept the definitions (the dictionary), leaving consumers confused.
4. The Five-Taste Reset: You can train your palate at home using sugar, lemon, salt, baking soda, and soy sauce to create clear reference points.
5. Curiosity Over Categorization: True tasting is about staying curious and sitting with the cup, rather than rushing to label it for social belonging.

The Five-Taste Reset Exercise

Before you pick up your next cup of coffee, spend ten minutes with these five basic tastes to recalibrate your tongue. This exercise creates clear, biological reference points so you can trust your own experience over the marketing on the bag.

• Sweetness (The Solution): Dissolve one tablespoon of sugar in warm water. This provides a clean, simple reference for sweetness without any outside argument.
• Acidity (The Sour): Use a fresh squeeze of lemon juice. Forget the "bright acidity" descriptions on a coffee bag for a moment; this is the raw reference for acid.
• Saltiness (The Amplifier): Mix half a teaspoon of salt into water. Sodium acts as an amplifier for the flavors around it.
• Bitterness (The Quinine): Dissolve two teaspoons of baking soda in water, or use tonic water as an alternative. The quinine in tonic water is a clear bitter reference that translates directly to the coffee experience.
• Savory (The Depth): Dilute a small amount of soy sauce or a splash of Worcestershire sauce. This represents "umami"—the depth and roundness that makes a cup feel complete.The Goal: Taste these five solutions in a row, then immediately drink your coffee slowly. You might be surprised to find that you already know exactly what is in your cup

The Temperature of Flavor

Have you ever felt like specialty coffee tasting notes were a marketing scam? You buy a bag promising "blueberry and chocolate," but all you taste is bitter, scalding heat. In this episode of La Taza Habla, 20-year industry veteran Don Cox reveals The Hot Lie: the physiological reason why your morning routine is actually masking the best flavors of your beans.

We dive deep into the science of the TRPM5 taste receptor—the "bouncer" of your palate—and explain how extreme heat forces your tongue into survival mode. You’ll learn about the temperature descent, a professional coffee roasting and grading protocol that separates commodity coffee from true specialty grade. Whether you are brewing a bright Kenyan or a chocolatey Colombian, the real story doesn’t begin until the steam stops rising. Don shares his "Cool Cup Challenge," a simple 10-minute ritual to help you stop pouring flavor down the drain and start tasting coffee the way a professional Q Grader does.

5 Key Takeaways

1. Heat is a Mask: Temperatures above 160°F trigger a defense mechanism in your taste buds, drowning out subtle flavors.
2. The 95° Window: Human flavor sensitivity peaks near body temperature (approx. 95°F).
3. Cooling is a Lie Detector: High-quality coffee gets sweeter as it cools; low-quality coffee reveals its defects.
4. Surface Area Matters: Using a wide, shallow ceramic mug helps coffee cool faster and more evenly than a narrow travel tumbler.
5. Complexity takes Time: Coffee is a 10-minute narrative; rushing the cup means you only hear the "opening credits of a movie."

The Sound of Flavor

In this episode of La Taza Habla, I explore why the secret to identifying your coffee’s flavor profile might not be in your taste buds, but in your ears. Drawing on 20 years of roasting coffee, I break down a revolutionary sensory framework called the "Listener’s Guide to Flavor". This approach moves beyond technical coffee roasting metrics like brew ratios and temperatures to help you find the emotional "imprint" of a cup.

I'll take you on a journey through the six distinct stages of a sensory experience: the Whisper, the Echo, the Voice, the Breath, the Bell, and the Imprint. From the "barely there" moment of a low-intensity flavor to the resonant "ring" of a truly great bean-to-cup story, you will learn how to "lean in" to your coffee rather than panicking during a traditional cupping. Whether you are a seasoned pro or a home enthusiast, this episode will teach you how to stop chasing a caffeine fix and start seeking a feeling that lingers long after the cup is empty.

5 Key Takeaways

1. Low Intensity is Not a Flaw: A "distant" flavor isn't weak; it is an invitation to lean in and pay closer attention to the coffee’s subtle nuances.
2. Don’t Panic During the "Echo": It is normal to hear a flavor "signal" before you can name the source (like chocolate or nut); the journey is part of the process.
3. Identify the "Voice": Great specialty coffees are distinct but not aggressive; they step into the light to tell you who they are without shouting.
4. Feel the "Breath": High-quality coffee has "presence" that expands like wind through trees, creating a physical sensation in your chest.
5. Seek the "Imprint": The ultimate goal of coffee appreciation is the emotional memory—the "residue" that makes you remember the feeling an hour later.

Tasting in Color

Stop settling for a morning cup that tastes like a "sun-bleached grey" wasteland. In this episode of La Taza Habla, we draw on 20 years of specialty coffee expertise to transform your daily ritual from a caffeine hit into a "moment of beauty". Just as Ansel Adams uses colored filters to find definition in a landscape, you can use coffee tasting and color as a tool to separate complex sensory signals.

We explore the concept of "associative synthesis"—how your brain uses a sensory library to organize a flood of information into simple labels. Whether you are identifying a "bright and friendly" strawberry note or a "deeper, jammy" blackberry tone, you are learning to navigate the specialty coffee flavor wheel by moving toward red or purple hues. From the mountains of Costa Rica to your kitchen table, learn why your personal memories—like "green bananas" or "chili anchos"—are the keys to unlocking coffee flavors  and cup clarity.

5 Takeaways

1. Color is a Filter, Not a Flavor: Color acts as a mental "folder" to help separate a "flat blob" of taste into individual notes like acidity, sweetness, and body.
2. The "Red to Purple" Spectrum: If a coffee feels light and floral, move toward "red" labels; if it feels deep and jammy, move toward "purple".
3. Tasting is Subjective Expertise: Two people can be "right" about different flavors (e.g., green banana vs. chili) because they are reaching into different personal reference libraries.
4. Your Palate is Always Training: You have 10,000 taste buds that regenerate every few weeks, meaning your ability to taste is a skill being built, not a fixed gift.
5. Cooling Reveals the Truth: As coffee cools, bitterness recedes and the "gray wasteland" pulls away, allowing the cup’s true character to talk.

3 Exercises to Learning to Taste in Color

Yellow = Lemon brightness

Sip a lightly diluted lemon-water and notice that lively, mouth-watering “sparkle.” Then look for that same kind of lift in a lighter roast.

Purple = Jammy berry depth

Taste a spoon of blackberry jam (or a sip of blackberry juice). Notice the darker fruit sweetness and the “jammy” feeling.

Brown/Black = Dark chocolate foundation

Taste a square of very dark chocolate and notice the grounding cocoa bitterness. This helps you tell the difference between “chocolate-brown” and “just burnt.”

Remember - You’re building a reference library. If you can’t find “blueberry,” your brain might shout “purple!” first—and that’s still useful. The goal is confidence and clarity, one cup at a time.

Coffeehouse Crossroads - 20 Years of Bean to Cup Equity

In the final installment of our coffeehouse trilogy, host Don Cox of Bald Guy Brew takes us behind the scenes of specialty coffee and the accidental birth of a community staple. What started as a simple passion for coffee roasting—the straightforward act of "making green beans brown"—evolved into a profound lesson in community-led design. Following a devastating fire, the roastery was rebuilt not through a grand corporate vision, but through repurposed materials and the kindness of neighbors who decided to stay.

This episode transitions from the local "third space" to the global farm and origin, challenging the colonial history and extractive financial models that have long marginalized the people behind the coffee. By focusing on equity for growers. we explore how every cup can be an act of resistance against a legacy of inequity. Join us at the crossroads as we discuss how to ensure the bean to cup journey reflects the same kindness found within our own cafe walls.

Five Takeaways

1. Community over Design: A true "third space" isn't created by a design philosophy; it is born when a community decides a space is safe enough to stay.
2. Resilience in Repurposing: Limitations—like having "no pennies to rub together"—can lead to more authentic spaces built with friends and salvaged scraps.
3. The Ethics of Origin: The specialty coffee industry must move past its colonial roots where land was displaced and producers were pushed to the margins.
4. Kindness as Resistance: Choosing equitable financial models is a deliberate stand against the historical "bullies" of the global supply chain.
5. The Power of One Cup: Small choices in what we consume can spark movements of change that stretch across centuries.

Part 2 - Boston: The Patriotic Origins of Specialty Coffee

In this episode of La Taza Habla, we dive into the origin of America’s caffeine obsession, tracing it back to the cold waters of Boston Harbor. While many know the Boston Tea Party as a political protest, few realize it was the moment specialty coffee began its journey toward becoming the patriotic drink of a new nation. We explore the "paradox" of the tea boycott: how Parliament actually lowered tea prices, yet the Sons of Liberty rejected it because a cheap cup became too expensive to drink morally.

Drawing on 20 years of experience, I discuss how the Green Dragon Tavern served as the headquarters for revolution, transforming coffee houses from simple gathering places into engines of social change. From John Adams’ personal sacrifice to the modern supply chains and farmers we support today, this episode examines why what is in your cup still matters. We aren't just coffee roasting for flavor; we are roasting for a legacy of freedom and human dignity.

5 Takeaways

1. Conviction Over Comfort: Resistance in 1773 required colonists to give up familiar rituals like tea because they became symbols of submission.
2. The Price Paradox: The cheapest option isn't always the one that costs the least; sometimes low prices mask a high moral cost.
3. Coffee as Participation: While tea belonged to the refinement of the Empire, coffee became the drink of participation and the common people.
4. Habit vs. Values: In the 1770s, "taste followed conviction," proving that people can and will change their habits for their beliefs.
5. The Coffee House Ideal: Beyond the building, a coffee house is a place where neighbors can disagree on politics but still share a table.
