Geotrophic is the North American version of the French word terrior but scientific in nature. Differences in wind, temperature, soil conditions can all be quantified when describing the geotrophic conditions of different wineries.
The subltle differences in wines from Sonoma Pinot Noir grapes can be attributed to geotrophic diffences in the soil acidity, average rainfall, average windspeed and average temperature which affect the growth and taste of the grapes.
