Mac got into food and wine during his early twenties via his friends and coworkers at Trader Joe's in Southern California. He soon began taking trips up to the Central Coast to just to taste, but quickly found himself volunteering his time on his days off to help out at a number of wineries. After learning the process for a few years and spending more and more time on the Central Coast, Mac was ready to start making wine for himself.

Helen and Dave Dart started their dream as home winemakers with a passion for great wines. After winning several awards in that category, they decided to make small lot commercial wines to share with like-minded enthusiasts.

What does a Spanish dancer have to do with a winery that has a French name? Absolutely nothing and everything. It was one of the first artworks created by Dave around the same time he and Helen began making wine at home. This piece has served as the winery's logo since their days as garagistes. Their journey began when they took Best of Show at the Sacramento Home Winemakers wine competition with their very first wine, a 2000 Syrah, igniting their passion for winemaking. Although Helen has French heritage, the name Dart is purely English.

Now residing on their Cabernet Sauvignon vineyard, where the winery is located, the tasting room is a feast for the eyes. Dave and Helen have adorned the space with Dave's photo art, reflecting their travels around the world. Most days, Helen is present in the tasting room, eager to share her special wine-pairing recipes and insights into winemaking.

Through the tasting room lies the barrel room, where Dave and his daughter, Jessie, handle the winemaking process. They divide their responsibilities, with Jessie managing fermentation and barrel aging while Dave focuses on master blending and bottling.

The d’Art team is their most valuable asset. Visitors are warmly welcomed in the tasting room, where the couple loves getting to know their customers.
