A guest on the aft deck says she "only drinks dry whites, nothing oaky." Ten minutes later she is delighted by a white Burgundy that spent nine months in barrel. She was not wrong and neither were you — she just did not have the words. Your job over this course is to build those words, so you can hear what a guest actually wants and put the right glass in front of them.
Before anything else: what this course is
xplor is not a WSET Approved Programme Provider and is not an accredited GUEST training provider. This is preparatory study only: no qualification, examination or certificate is awarded here, and nothing in this course counts toward one. Should you separately wish to hold the WSET Level 2 Award in Wines, it must be studied and examined through a WSET Approved Programme Provider. For reference: that award is accepted by the GUEST Program (governed by IAMI) as an equivalent for its Unit 13.
Where wine style comes from
Every wine in the fridge is the sum of three things. Nothing else. If you can locate a wine on these three, you can describe it.
| Input | What it decides | Example |
|---|---|---|
| The grape variety | Aroma family, natural acidity, tannin, colour | Sauvignon Blanc is always high-acid and herbaceous-ish; Cabernet always has firm tannin |
| The growing environment | Ripeness — sugar, acid, fruit character | Cool climate Chardonnay tastes of green apple; warm climate Chardonnay tastes of peach |
| The winemaking | Texture, oak, bubbles, sweetness, ageing | Same grape, same place: one wine in steel, one in barrel, two different wines |
The grape variety: the raw material
A variety brings fixed traits. Riesling is high in acid and low in tannin wherever it grows. Cabernet Sauvignon has thick skins, so it gives deep colour and high tannin. Pinot Noir has thin skins, so it gives pale colour and light tannin — and no winemaker on earth can make it look like Cabernet.
Climate: the single most useful idea
Broadly, growing regions are described as:
- Cool — grapes struggle to ripen. Result: high acidity, lower alcohol, green fruit (apple, citrus, cranberry). Think Chablis, the Mosel, Champagne.
- Moderate — a middle path. Red fruit and stone fruit, medium acidity. Think Bordeaux, Burgundy, much of northern Italy.
- Warm — ripening is easy. Result: lower acidity, higher alcohol, ripe black or tropical fruit. Think Barossa, the southern Rhône, much of California.
That single axis explains more guest preferences than any other. A guest who "finds Chardonnay too heavy" usually means warm-climate, oaked Chardonnay — and will happily drink Chablis, which is the same grape grown cool and left in steel.
What ripeness actually changes
As a grape ripens through the season: sugar rises (so potential alcohol rises), acidity falls, and flavours move from green to ripe to dried. Green apple becomes peach becomes tinned pineapple; cranberry becomes plum becomes prune. Sparkling grapes are picked early to hold that high acid.
Onboard Notes
- Never argue with a guest preference. Translate it. "No oak" means steel-fermented; "not too dry" usually means fruity, not sweet.
- The three-input model is your fastest tool. Grape, place, winemaking — say those and you have described any wine on board.
- Keep this course honest in front of guests: you are studying wine, and this study confers no certificate of any kind.
