Raising the alps, has not just characterized our soils. Waterways has deeply engraved the surface bringing to light some submerged layers, while giving an irregular shape to our hills and giving them various exposures to the sun. Exposures that bring heterogeneous microclimates to exist, depending from the amplitude of the valleys, steepness and wind protection.
More maple, or higher valleys present higher gradient of temperature, while closed valleys tend to show the opposite. Warmer valleys will show bodied and generous wines, while cooler areas show more thin ones.
South East to South West facing areas are warmer, showing deeper wines. Within same hills, different microclimate can be observed: with ridges more exposed to extreme weather, while central parts more homogeneous and lower parts more humid.
Generally speaking, Barbaresco tends to be a little bit warmer than Barolo, since its exposure to warm winds from North-East flat, and the lower influence from the cooler South-West mountain winds. This is enough to anticipate by one week the harvest. This comparison is fundamental to complete the previous based on the soil, to give an extended understanding to the comprehension of the Langhe terroir and Nebbiolo expressions.
