Calcareous Vineyards is located on Peachy Canyon Road in the westside hills of Paso Robles, California. Established in 2000, Calcareous Vineyards is a 442 acre estate that begins about one mile to the west of town and stretches for several miles towards the beautiful Pacific Ocean.
The expanse of this land offers many opportunities for optimal vineyard sites and varietal selections. The benefit of the westside of Paso Robles is the terrain allows for the production of Bordeaux, Rhone, and Burgundy varietals virtually side-by-side. The limestone soils were derived from the sea-life once covering these hills in pre-historic times; creating the foundation for a great vineyard. The hills emerged from the depths of the ocean by the colliding forces of geological plates and volcanic eruption; this has created varied microclimates on the sides of the hills, due to the different exposures to sun, wind, and rain.
Our search for the perfect combination of terroir, climate and varietal selection brought us to the Central Coast of California, and more specifically to the rare and unique calcareous soils of west Paso Robles. Our goal is to produce the finest Rhone and Bordeaux blends and distinctive Burgundies this region will allow.
Planted in 1968, this vineyard consists of 9 Acres of Cabernet Sauvignon, 4 acres of Pinot Noir, and 2 acres of Chardonnay nestled amongst an oak forest. The Carver Vineyard is located in the York Mountain AVA, a separate region on the western edge of the Paso Robles AVA. The vineyard is located just 6 miles from the Pacific Ocean near the crest of the Santa Lucia mountain range. This extreme western local and high elevation makes it much cooler and has much deeper soils than our Paso Robles vineyards making it a perfect location for these cool climate loving varietals.
Due to being a separate AVA, the grapes from Carver are only used to produce single-varietal vineyard designate wines. This vineyard is truly one of the jewels of the area and we couldn't be luckier to have it as part of our Estate.
All of the Zinfandel we use comes from Kate's. It is located 1/2 mile south-east of the Calcareous Tasting room. In fact, you can see the top of it from our Bocce Ball court. It consists of 12 acres of Zinfandel planted in 1988. The rolling hill terrain creates vast differences in soil type, moisture and sun exposure throughout the 5 separate blocks. On one side is block 1 that sits in rich wet soil at the base of north facing slope covered in oaks. This allows for dry farming and yields around 4-tons to the acre and is used for our Twisted Sisters Zin and Main Squeeze. To the other extreme is block 4 which sits on top of a rocky chalk outcropping facing directly south-west. This 1-ton to the acre section produces tiny berries of intense richness and structure and is mainly responsible for the flavors in our Estate Zinfandel.
