What is “mountain fruit”
-Refers to (usually) Cabernet Sauvignon from Napa’s sun-drenched hillside vineyards and mountainside AVAs
-prized for density, dark fruit, concentration and ability to retain good acid structure through ripeness
-Low nutrient soils make grapes struggle and produces smaller berries, influencing color, intensity and a higher level of tannins.
-The reason is the increased level of light intensity and affect of the inversion layer that creates these more intense, powerful wines
-Basically The higher you are in the hills, the warmer nights and cooler the days. Initially ripening is slower for mountain fruit, but by the end of the summer the tannin and color have rocketed ahead….very different profile from the valley floor where the cool nights preserve aromatic freshness and you end up with more elegant Cabs.
