Terroir is a French word that could resemble “terroir” in Spanish.
It is based on the French word “terre” which means soil, for what some people define as terroir, simply to the earth, but with this definition we may be too short.
But terroir is actually much more complex than just land. The terroir is the combination of different natural factors of a space: How is the soil, the subsoil, the climate that occurs in that particular space, the slope where it is located or the altitude; and that they print the character and the particularities that a vineyard in particular has.
The most probable thing is that there are not two vineyards in the whole world with the same combination of these factors, that is why this terroir is so important and defining the fruit that it will finally end up giving.
