What is Terroir?
Terroir is one of the most-used and least-understood words in wine. At its simplest, it means the combination of soil, climate, geography and tradition that gives a wine from one place its distinctive character — the reason a Pinot Noir from Burgundy tastes different from a Pinot Noir from California even when they are made from the same grape.
Soil
The composition of the soil affects how vines grow, what minerals they take up, and how water moves through the vineyard. Limestone, clay, granite, slate and volcanic soils all produce wines with different characters.
Climate
Temperature, rainfall, sunlight and the length of the growing season all shape the grapes. Cool-climate sites produce wines with high acidity and lower alcohol; warm-climate sites produce richer, riper wines.
Geography
Slope, aspect, altitude and proximity to water all matter. South-facing slopes get more sun (in the Northern Hemisphere), high-altitude vineyards have cooler nights, and proximity to a river or ocean moderates extremes.
Tradition
Many wine writers include human practice as part of terroir — the local tradition of how vines are pruned, what grapes are grown, and how wine is made. These choices are inseparable from the place itself.

Frequently Asked Questions
Is terroir real or just a marketing term?
It is real. Blind tasting consistently shows that experienced tasters can identify wines from specific places, and the chemical and sensory differences between sites are measurable.
Can you taste terroir?
Yes, with practice. The difference between a Sancerre and a Marlborough Sauvignon Blanc, both from the same grape, is largely terroir.
Do New World wines have terroir?
Absolutely. Napa, Sonoma, Willamette, Walla Walla and other top New World regions all show clear site-driven character.
