Horizontal tasting
Tasting several different wines from the same vintage, to isolate producer and site.
A horizontal tasting compares several different wines from the same vintage. Because the growing season is held constant, everything you notice comes from somewhere else: the site, the grower's decisions, the winemaking, the grape.
It is the standard format for comparing an appellation's producers, or a vintage's performance across neighbouring villages — the professional trade's default way to learn a region.
In practice
- Hold one variable fixed (the vintage) and vary one other — producer, village, or grape.
- Six to twelve wines is the practical range before palate fatigue sets in.
- Serve blind where possible: labels do most tasters' thinking for them.
- Pour in a deliberate order — lighter to fuller, dry to sweet — and keep temperature and glassware identical.
Where you'll meet it
Horizontal versus vertical
| Horizontal | Vertical | |
|---|---|---|
| Constant | The vintage | The wine |
| Variable | Producer, site, grape | The vintage |
| Teaches | Terroir, house style, appellation character | Ageing, vintage variation, development |
Run both on the same region and you have covered its two axes: what varies across space, and what varies across time.
Designing one that teaches something
- Choose one question. "What does premier cru actually buy you in Chablis?" makes a better flight than "twelve nice whites".
- Control the trivia. Same glass, same temperature, same pour size — small differences distort comparison more than people expect.
- Taste in silence first, then discuss. Talking early anchors the room on whoever speaks loudest.
- Write before revealing. A note written blind is worth ten written after you've seen the label.
