At Slope and Intercept we believe that wine is about moments past and present. The lifeline of a wine is made up of many moments. A good bottle of wine brings all these moments together when it is opened.

In each bottle of Slope and Intercept wine you will find a sensory description of the varietals, time, place and human effort that all play a role in the final product. We at Slope and Intercept cherish the wine regions of the West Coast. We make wine from the West Coast grapes that reflect our lives and the places we love.

A line is a deceptively simple thing, as is a bottle of wine. But in both the final product represents a complex assembly of pieces. Points on a line, moments in time: these are what ultimately influence the final product. We invite you to enjoy the moment you open a bottle of our wine with thoughts of all the other moments that led up to it—in the wine’s life and in yours.

Jason Joyce approaches winemaking with the same philosophy he applies to his daily life: the small parts that make up the whole are what are truly important. Each day is made up of moments, and Jason lives in these. For a winemaker the tasks of the day vary from week to week and season to season. Crafting wine is art and science, construction and demolition, deskwork and physical activity.

Jason graduated from Cal Poly in San Luis Obispo, CA with a degree in organic chemistry. He worked for several years as a synthetic chemist in San Francisco’s biotech industry. He found the work to be interesting and meaningful, but found also that it did not allow him much room for spontaneity and exploration.

In 2007 Jason’s search for a more holistic occupation led him to a job as a harvest cellar hand in Paso Robles, CA. He continued on in Paso Robles’ growing wine industry, and became head winemaker at a boutique winery on Paso Robles’ west side. In 2013 he began making wine for his own label, Slope and Intercept. This project has allowed him to explore the craft of winemaking from a new and rewarding perspective.

We make house calls: our winemaker will come to your home or hotel in the Paso Robles area to do a private tasting with your group. Tastings are also available at our winemaking facility in westside Paso Robles by appointment.
