Viña Casa Marín is located in a privileged and unique terroir but one that can seem adverse. The town of Lo Abarca is just 4 kms. from the Pacific Ocean and is covered by a constant fog during the summer and winter months. It’s also a very windy area with cold temperatures during the grape growth and ripening period. However, these conditions make the vines produced a superior quality fruit than other valleys with higher temperatures and with massive production. The harvests are not abundant, but the plants that grow here are strong with healthy grapes and greater flavor and mineral concentration that add unique qualities and character to the wines.
According to geologists, this area was once part of the ocean which is why there have been high levels of calcium and minerals (each adds to the grapes) found in excavations the winery has done. In fact this is where the new plant name “tierras blancas” (white soil) came from because of its color and the abundant presence of calcium carbonate. Casa Marín’s terroir is made up of 50 hectares of hills and valleys, of which 10 newly planted. The winery has 8 sections divided into 38 blocks, each with distinct geological and geographic characteristics and planted with its respective grape variety.
They are:
Casona Vineyard
This section has a north-south orientation and is located at the edge of the town Lo Abarca. It has thick, dark clay soil that is difficult to remove but very fertile and deep, which gives life to the German-Italian variety Gewürztraminer.
Laurel Vineyard
This block’s variety is Sauvignon Blanc, which grows stronger in a calcareous and clay soil. It has a northeast exposition and faces Lo Abarca. 100% of the vines are located on an hillside, which means the vines use a drip irrigation system. This terroir had never before been used for agriculture and before only had native vegetation.
Cipreses Vineyard
From the beginning, this block has been designated for our delicious Sauvignon Blanc. Regarding its geographic characteristics, this land faces the towns of Lo Zárate and Lo Abarca and its rows run north to south. It is situated on a hillside facing the ocean with red clay soil with gravel, precisely because of its proximity to the ocean.
Miramar Norte Vineyard
This block nurtures the Syrah vines fervently, which are able to withstand the extremely cold climate during the winter as well as winds throughout the year. It is composed of red clay soil of volcanic origin that allows for good drainage.
Miramar Vineyard
This windy block is located at the highest part of the vineyard, 300 meters above sea level, and is planted with Riesling, a variety that thrives in volcanic and clay loam soil.
Estero Vineyard
This block overlooks the stream, facing Cartagena and is where our Sauvignon is planted. The soil is low in fertility because the top half is clay and the bottom, sandy. However, this makes delicious wines. The rows face the town of Lo Zarate on a pronounced slope between 30 and 32 degrees of unevenness.
Lo Abarca Vineyard
Pinot Noir thrives in this block. It has low slopes; calcareous soils with some clay, lime and silt (loose material similar to fine sand and clay faces the ocean and each row is planted on a slope.
