This is what is meant by a Continental Climate, warm summers and cold winters. During the summers temperatures range between 50° nights and 85° days much like our climate here in Colorado. In addition, the Southern Alps act as what is called a rain shadow, blocking much of the moisture from passing into the region thereby creating one of the driest parts of New Zealand. All of this adds up to a special place for Pinot Noir.
Let’s not forget about Edoras, the capital of Rohan, home of the horse lords. This is actually the Canterbury region in New Zealand right next to Marlborough. Rightly known as the source of some of the world’s great Sauvignon Blancs, it is home to some terrific Pinot Noirs as well. Central Otago Pinot noirs have become characterized as "fruit bombs"—big, soft textured, wines, rich in flavors like boysenberry while Marlborough Pinots tend to be a little earthier.
Pinot is what is known as a cool climate grape, it does its best work in marginal climates like New Zealand. While it may be cooler, there is plenty of sunshine to help ripen those grapes as during the summer months, daylight can last until 10pm. Pinot is also very prone to mildew and rot, so a dry climate during the growing season is necessary to get high quality fruit. Now we see the importance of those mountains.
