The owner tastes the Chablis you poured and asks, quite genuinely, why it costs four times the Macon he liked last week. Naming the region is not an answer. Explaining is: a cooler site, lower yields, older vines, a stricter appellation, and a wine with the acidity and concentration to age a decade. That shift, from naming to explaining, is the whole point of this course.
What this course is, and is not
xplor is not a WSET Approved Programme Provider and is not affiliated with WSET. This is preparatory study only: no WSET qualification, examination or certificate is awarded here, and nothing in this course counts toward one. If you separately wish to pursue the WSET Level 3 Award in Wines, it must be studied and examined through a WSET Approved Programme Provider, who supplies the official study materials and runs the examination. Nothing here reproduces WSET material: the tasting structure taught in this course is our own equivalent approach, written in our own words, and it is not the WSET Systematic Approach to Tasting. Whatever route you take, there is no substitute for tasting real wine, regularly, ideally alongside others. Taste and spit, and drink responsibly.
From naming to explaining
Naming asks what. This course asks why and so what.
| Question | Naming | Explaining |
|---|---|---|
| Why is this Barossa Shiraz so full-bodied? | It is Australian Shiraz | Hot climate, high ripeness, high alcohol, ripe tannin, generous new oak |
| Why is this Sancerre so sharp? | It is Sauvignon Blanc | Cool continental site, early picking, no malolactic conversion, no oak |
| Is this a quality wine? | It is expensive | Balanced, long, complex, intense, typical of origin |
Every judgement you make must be justified by a cause. There are only four families of cause, and this course is built on them:
- The growing environment — climate, weather, latitude, altitude, aspect, slope, water, soil.
- Viticulture — canopy, yield, harvest date, vine age, hazards and disease.
- Winemaking — vessel, temperature, extraction, malolactic conversion, oak, lees, blending, maturation.
- Maturation and handling after bottling — including everything you do to the bottle onboard.
Climate versus weather
These are not synonyms, and confusing them is the classic error.
- Climate is the long-term average pattern of a place. It does not change from year to year. Cool, moderate, warm and hot are climate descriptions.
- Weather is what actually happened in one growing season: the frost in April, the rain at harvest, the heat spike in August. Weather is what creates vintage variation.
A region has a climate. A vintage has weather. When a guest asks why 2013 red Bordeaux is cheap and 2010 is not, the answer lives in weather, not climate.
How to study this
Taste with the structure in front of you. For every wine, write one sentence of description and one sentence of cause. If you cannot supply the cause, you have not learned the wine yet. Regions in this course are taught as style-generating machines, not as lists to memorise.
Onboard Notes
This is the point at which a chief stew or yacht sommelier stops being a server of wine and starts being an adviser on it. The owner is not testing your memory; they are testing whether you can tell them, in plain language and in ten seconds, whether a bottle is worth what it costs and whether tonight is the night to open it.
