Rose isn't actually a blending or watering down of a red wine to make it pink. Rose' wines are made exactly the same way a red wine is made. The only difference is that the winemakers leave all the skins, seeds, pulp, etc in the barrel with the juice for only a few hours. Wine gets it's color from grape skins. The longer the contact with the skins the darker the wine. Some red wines are soaked (maceration) for a few days to 10 days or more. If you cut any red grape open the juice is clear and the innards are usually green.
Rose can be made from any red grape. I've had merlot, shiraz, cabernet sauvignon, cabernet franc, etc rose's from all over the world and they all taste different from the different types of grapes used.
Rose's are one of my favorites and are one of the most under-estimated and best wines out there. Killer with many types of food. Drink the pink.....
