Out of all the wines in the world, pinot noir is one of the most expensive. The reason why is because the grapes used to make pinot noir wines are so difficult to grow. They require certain soils and weather conditions to truly thrive, and so it can be tricky for wineries to master growing these grapes.  Because of this, pinot noir is more valuable and sought-after. This drives up the price, making it expensive to taste lots of different varieties to find the right one for you. This is why wine tasting events like the Pinot Days Grand Festival at Chicago are a great opportunity to taste lots of pinot noirs to find the best one for you.
