California is famous for producing world-class wines. The epicenter of California wine making is Napa Valley. Napa means “the land of plenty” in the Native American language of Wappo. Today’s Napa certainly lives up to the meaning of its name.┬áNapa Valley is known for its luxury hotels, elegant restaurants, and of course some of the best wines in the world.

What Makes Napa Valley Unique?

Napa Valley has a perfect combination of climate, soil, and terrain ideally equipped for growing wine grapes. This unique terroir has made Napa Valley virtually destined to make some of the best wine ever produced.

Napa Valley’s Unique Climate

Napa Valley’s climate is very rare—the summers are warm, the winters are mild, and it only rains for a few months a year. This gives the vines a long growing season. The warm days allow the grape to ripen and develop deep flavor and sugar—which later ferment into alcohol. Meanwhile, the cool morning fogs allow the vines to rest and preserve acid in the fruit.

Napa Valley’s Rich Soil

The soils in Napa Valley are extremely diverse, with 100+ types of soil—about half of the soil types that exist on earth. Half of the world’s 12 recognized soil orders and 33 different soil series are found in the region. Napa Valley is also unique because it contains volcanic soils—offering these wines a flavor that is entirely unique to this region. Volcanic materials also create some of the most fertile soils on the planet.

Napa Valley’s Terrain

Relatively speaking, Napa Valley is a small winemaking region—it is just 30 miles long and 5 miles wide. In contrast, Bordeaux in France is eight times larger than Napa Valley. Despite the small size of Napa Valley, it’s topographical diversity more than makes up for it in the wines it produces. Napa Valley is home to mountain terrain, valley floors, and benchlands—flat terrain surrounded by high slopes.

These landscapes allow vineyards to produce a wide variety of grapes, including:

  • Cabernet Sauvignon
  • Chardonnay
  • Pinot Noir
  • Merlot
  • Sauvignon Blanc
  • Sangiovese
  • Zinfandel

Diamond Mountain

Theorem is located on Diamond Mountain--just southwest of Calistoga. This region is famous for producing ultra-premium Cabernet Sauvignon because of the elevation, climate, and soils. Diamond Mountain’s microclimate is characterized by warmer nights and cooler days, making it an ideal location to produce luxury wines that can age for years.

Growing vines on the steep slopes of Diamond Mountain takes considerable skill, expertise, and resources. Besides being an ideal location to make high-end wines, Diamond Mountain provides some of the best views in all of Napa Valley.
