Wine Aromas: The Language of Tasting Notes
A wine made only from grapes can smell convincingly of cherries, pencil shavings, violets, leather and wet stone. This is not fancifulness or marketing: it is real chemistry. Wine contains hundreds of aromatic compounds, many identical to those found in other fruits, flowers and foods, and learning to name them is the heart of tasting. The vocabulary of tasting notes is simply a way of organising what your nose already detects.
Why wine smells of things it isn't
The aromas in wine come from volatile compounds — molecules light enough to evaporate and reach the smell receptors in your nose. Many of these are the very same molecules that give other things their scent: the compound that smells of green pepper in Cabernet Franc is the same one found in actual green peppers; the violet note in Nebbiolo comes from a compound called ionone, also responsible for the scent of violets. When you say a wine smells of blackberry, you are detecting a genuine chemical kinship.
Primary aromas: the grape and place
Primary aromas come from the grape itself and the conditions it grew in. These are the fruit, floral, herbal and mineral notes — citrus and green apple in a cool-climate white, blackcurrant and mint in a Cabernet, peach and apricot in a Viognier. Primary aromas are the clearest signal of grape variety and climate: riper fruit suggests warmth, fresher and greener fruit suggests cooler conditions.
Secondary aromas: the winemaking
Secondary aromas come from the winemaking process, especially fermentation and any malolactic conversion. The buttery, creamy note in many Chardonnays comes from a compound (diacetyl) produced during malolactic conversion. The yeasty, bready, biscuit notes of Champagne come from ageing on the lees. Even the faint smell of fresh dough or brioche in some whites is a secondary, winemaking-derived aroma rather than anything from the grape.
Tertiary aromas: bottle age
Tertiary aromas develop slowly as a wine matures in bottle, as the primary fruit recedes and complex new compounds form. A young red's bright cherry can evolve into dried fig, leather, tobacco, forest floor, truffle and game; a white's fresh citrus can become honey, nuts, dried apricot and a petrol-like note (a famous, prized marker of aged Riesling). These developed aromas are what wine lovers mean by complexity, and they are the reward for patient cellaring.
The aroma wheel
To organise this flood of impressions, the wine educator Ann Noble created the Aroma Wheel at the University of California, Davis, in 1984. It works from the general to the specific: a broad category like "fruity" leads to "berry", which leads to "blackberry". The wheel is a training tool that helps a taster move from a vague sense of "fruit" to a precise descriptor, building a reliable personal vocabulary over time.
Building your own vocabulary
The best way to learn aromas is to smell deliberately, everywhere — fruits, herbs, spices, flowers, damp earth, leather, coffee. The trained taster is not gifted with a better nose but with a better memory for scents and the words attached to them. When you taste, swirl to release the volatiles, take short sniffs, and try to name three things before reaching for a reference. Your descriptors do not need to match anyone else's; they need to be consistent for you.
From aroma to tasting note
A complete tasting note moves through appearance, aroma, palate and finish, but aroma is where most of the information lives — the nose detects thousands of distinct smells, the tongue only five basic tastes. A good note records the intensity, the specific aromas across the three categories, and how they evolve in the glass. Written down over time, your notes become a map of your own palate and a record of how wines change.
