What you'll learn

  • Acidity in WineNaturally occurring acids in wine, primarily tartaric and malic acid, that create a tart, mouth-watering sensation on the tongue and are essential to a wine's structure.
  • Body in WineThe weight and fullness sensation of wine in the mouth, determined primarily by alcohol content, residual sugar, and other compounds.
  • Forming a Personal Wine AssessmentA brief, honest summary that synthesizes observations about a wine's appearance, aromas, and taste to describe its character, evaluate its balance, and form a meaningful conclusion.
  • Tannins in WineNaturally occurring compounds in grape skins, seeds, stems, and oak that create a dry, astringent tactile sensation in the mouth.
  • Alcohol in WineEthanol produced from yeast fermenting grape sugars that generates warmth and weight in the mouth and should feel balanced with the rest of the wine's character.
  • Analytical vs. Casual TastingThe deliberate examination of a wine's appearance, aroma, and flavor through systematic observation, as opposed to casual drinking where the wine provides broad impressions alongside food or conversation.
  • The Five S's FrameworkA structured sequence of See, Swirl, Sniff, Sip, Savor that provides a consistent order for engaging each sensory phase during wine tasting.
  • Sweetness in WineThe perception of residual sugar remaining dissolved in wine after fermentation, detected as a soft, rounded sensation on the palate.
  • Tertiary Aromas and BouquetThe complex scents that develop in wine through aging in oak barrels or extended maturation in the bottle, representing the voice of time and transformation.
  • Common Wine FaultsGenuine defects in wine caused by detectable chemical compounds or conditions that develop during production, storage, or handling, such as cork taint from TCA penetrating natural corks.
  • Tasting Environment and SetupThe physical conditions and equipment used during wine tasting that affect sensory perception, including glassware shape, lighting, and surrounding aromas.
  • Tasting Vocabulary and DescriptorsA shared set of reference points and comparisons that allows people to communicate meaningfully about wine's sensory qualities, since smell has no direct vocabulary of its own.
  • Primary AromasFruit, floral, and herbal scents that come directly from the grape variety itself before fermentation or aging occurs.
  • Finish and LengthThe collection of flavors and sensations that persist on the palate after swallowing, sometimes revealing new nuances distinct from what was tasted mid-sip.
  • Secondary AromasSmells produced by yeast and bacterial activity during fermentation that add complexity to the wine's character.
  • Wine Structure and BalanceThe underlying framework of acidity, tannin, alcohol, and sweetness in a wine that work together to create harmony and prevent the wine from tasting sharp, flat, or unbalanced.
  • Wine Appearance AssessmentThe evaluation of a wine's colour, depth, and clarity by holding the glass by the stem and tilting it over a white background to gather information about the grape, age, production method, and condition.
  • Oak Influence on WineThe deliberate choice by winemakers to age wine in oak barrels, which imparts wood flavors, allows controlled oxygen interaction, and transforms the wine's texture and structure.
  • Aroma IntensityThe strength or power of the scent a wine emits, independent of which specific aromas are present, assessed on a scale from neutral to pronounced.
  • Nosing TechniqueThe practice of swirling wine to increase volatile aromatic compounds in the glass headspace, then smelling to access the hundreds of distinct compounds your olfactory system can detect.
  • Wine Color and Age IndicatorsThe pigment molecules in wine, primarily anthocyanins in red wines, that change color as the wine ages due to chemical breakdown and polymerization.

About this course

What Is Analytical Wine Tasting?

Wine tasting — the kind taught in this course — is not about being an expert or impressing anyone. It is the practice of paying deliberate, structured attention to what a glass of wine actually does to your senses, and then finding words for it. Most people who drink wine regularly are already doing parts of this without realising it. You notice when a wine is unusually sharp, or when it smells like something you can almost name, or when one bottle just feels heavier in your mouth than another. Analytical tasting is simply what happens when you slow that process down and give it a framework.

The goal of this course is practical: by the end of it, you will be able to pick up any glass of wine, move through it systematically, and describe what you perceive with confidence and precision. You will not need to memorise grape-growing regions or vintage charts to do this. The skill is grounded entirely in what is happening in your glass and in your senses — which you already have.

Why It Matters Even If You're Not a Wine Professional

You might reasonably wonder whether this level of attention is only useful for sommeliers or wine critics. It is not. Here is what analytical tasting actually gives you as an everyday wine drinker:

  • A language for preference. Right now, you might know that you like some wines and not others, but struggle to say why. Analytical tasting lets you identify the specific qualities — high acidity, low tannin, a particular kind of fruitiness — that make a wine appealing to you, so you can seek them out and communicate them to a wine shop or restaurant.
  • More pleasure from the same glass. Attention deepens experience. A wine you might have drunk without noticing becomes something you can actually explore.
  • Confidence in wine situations. Whether you are choosing wine for a dinner, buying a bottle as a gift, or talking to a sommelier, having a working vocabulary removes the anxiety of not knowing what to say.
  • The ability to recognise faults. Some wines have genuine defects — musty smells, off flavours — that analytical tasting teaches you to identify so you can send a flawed bottle back or avoid a corked wine.

What the Senses Actually Do

Wine is chemically complex — a single glass contains hundreds of compounds that interact with your sight, smell, taste, and touch simultaneously. Analytical tasting organises these sensory inputs into manageable phases so you can assess them one at a time rather than all at once.

Sight gives you the first layer of information: the wine's colour, its depth, its clarity. These visual cues hint at grape variety, age, and winemaking style before you've smelled or tasted anything.

Smell is the most information-rich phase. The nose detects aromatic compounds both directly (sniffing the glass) and retronasally (while the wine is in your mouth, aromas travel up the back of your throat to your olfactory receptors). The distinctions between fresh fruit aromas, fermentation characters, and the complex notes that come from oak or bottle aging all live primarily in smell.

Taste and mouthfeel work together on the palate. The tongue detects sweetness, acidity, and bitterness, while tactile sensations tell you about tannin (that drying, gripping feeling in red wines) and body (how weighty or light the wine feels). Alcohol registers as warmth in the throat.

The finish — the flavours and sensations that linger after you swallow — is the final dimension, and in quality wines it is often the most memorable part.

The Framework You Will Use

This course organises the tasting process around the Five S's: See, Swirl, Sniff, Sip, and Savor. This sequence gives you a consistent, repeatable order in which to engage each sensory phase. It mirrors the structure used by formal wine education bodies worldwide, such as the Wine & Spirit Education Trust (WSET), but is stripped of jargon and made immediately usable.

The Five S's sequence moves from visual observation through aroma, palate, and finish — each phase building on the last.

The Building Blocks of Wine

Across these sensory phases, you will learn to identify and describe the key structural components that every wine contains in varying degrees:

  • Acidity — the tartness and freshness that makes your mouth water
  • Sweetness — from bone-dry to richly sweet, determined by how much sugar remains after fermentation
  • Tannin — the drying, gripping sensation from grape skins and seeds, present mainly in red wines
  • Alcohol — warmth in the throat, contributing to the wine's body and weight
  • Fruit character — the specific aromas and flavours drawn from the grape variety and growing conditions
  • Oak and aging influences — complexity added by barrel or bottle aging

Understanding these components separately is what allows you to describe a wine precisely, understand why it tastes the way it does, and connect it to what you genuinely enjoy.

What This Course Is Not

This course does not ask you to memorise the wine regions of France or learn the hierarchy of Burgundy appellations. It does not assume there is a correct way to experience a wine, and it does not treat connoisseurship as a goal. The authority in this course comes from your own perception — your senses, your memory, your honest reactions. Technical terms are introduced only when they help you name something you can actually perceive in the glass, not to build an impressive vocabulary for its own sake.

Wine has a long history of being made to feel intimidating and exclusionary. This course pushes directly against that. The only thing you need to begin is a glass of wine and a willingness to pay attention to it.
