Twin Oaks Valley Winery is located in San Marcos. This is a little bit unusual considering that most north county wineries are in either Temecula or Ramona, but Jacob Kappeler and his business partner Frank Bons, also neighbors, have found a niche for grapes on their combined lands. Jacob runs T&H Prime Meats & Sausages, an extensive butcher shop that makes a wide array of sausages made from chicken, turkey, pork, beef and even lamb. Frank used to grow roses but was eventually pushed out of the flower market by cheaper imports from South America. Together, they have 14 acres of vineyards planted with three types of grapes- Syrah, Cabernet Savignon, and Viogner. All of their wines are "estate" wines, meaning that they use only their own grapes, and they either perform themselves or oversee all parts of the winemaking process through to bottling. This is even more unusual, since most wineries around here buy at least some grapes from other estates. But Twin Oaks keeps it simple, with just five different wines. And not only can you get their label at T&H Meats, but you can find other local wines in the small wine-tasting/retail room adjacent to the butcher shop. Here's an interesting, though outdated article about them.
