The Best Wine Varietals to Find from San Diego Wineries

San Diego's unique climate and terrain make it an exciting region for wine production. Let's explore some of the California best wine varietals you should look for when visiting San Diego wineries, and dive into what makes this area special for winemaking.

San Diego's Wine-Friendly Climate

San Diego boasts a Mediterranean climate characterized by warm, dry summers and mild winters. The region receives an average of 266 days of sunshine per year, with coastal areas experiencing cooler temperatures due to ocean breezes, while inland areas see warmer conditions.

This climate diversity, coupled with varied elevations and soil types, creates numerous microclimates ideal for growing a wide range of grape varieties. The long, sunny days allow grapes to ripen fully, developing rich flavors, while the cooling influence of the Pacific Ocean helps maintain acidity in many areas.

The South Coast AVA

San Diego's wines fall under the South Coast American Viticultural Area (AVA), a large wine region encompassing parts of San Diego, Riverside, Los Angeles, and Orange counties. Within this AVA, San Diego County has several sub-regions, including the Ramona Valley AVA and the San Pasqual Valley AVA.

These areas benefit from decomposed granite soils, which provide excellent drainage and impart unique mineral characteristics to the wines. The combination of climate, soil, and dedicated winemakers has put San Diego on the map as an up-and-coming wine region.

Now, let's explore some of the best-suited grape varieties for San Diego's terroir:

Syrah/Shiraz

Originally from the Rhône Valley in France, Syrah thrives in San Diego's warm climate. The region's long, sunny days allow these grapes to develop rich flavors. Expect wines with notes of blackberry, plum, and black pepper, often with a hint of smokiness.

Grenache

This Spanish-origin grape loves heat and dry conditions – perfect for San Diego! Grenache wines typically offer bright red fruit flavors like strawberry and raspberry, with a touch of white pepper spice.

Another Spanish variety, Tempranillo adapts well to San Diego's warm summers. These wines often feature flavors of cherry and red plum, with subtle hints of leather and tobacco.

A white grape that handles heat well, Viognier originated in France's Rhône Valley. In San Diego, it produces aromatic wines with lush flavors of peach, tangerine, and honeysuckle.

Genetically identical to Zinfandel, this Italian variety loves San Diego's warm weather. Expect bold wines with flavors of ripe blackberry, cherry, and baking spices.
