Optima was a dream built on Passion and Hard Work

Our Craft

With a passion for winemaking that stretches over 36 years, we believe a bottle of wine tells a story. Open the bottle, and you taste the sun the fruit absorbed and the nights it survived. You follow the winery through the rows of the vines, waiting for the optimal moment to pick. You sense the shiver the farm workers have as they delicately hand pick each cluster in the early morning of the harvest day. Our Winemaker protects the clusters through sorting, crushing, fermenting and pressing. You smell the barrels he selected and feel the serenity of years soaking in the wood. You can trust we honored the vintage and gave the wine exactly what it needed to become the best it can be without manipulating the wine.

In your hands, a bottle of wine becomes part of another story. Your story, A wine will forever be intertwined with the occasion you opened it: weddings, birthday’s, holiday’s, bbq’s, or just about any night of the week. Our hope is you allow us to be a small part of what makes your life great.

This is the passion that drives us. The passion our winery was founded on to ensure you open a bottle that over delivers in every possible way. Enjoy!


Mike Duffy

Passion & A Lot of Hard Work

For Mike, owning a winery was the culmination of a labor of love and a dream fulfilled. It was apparent at an early age that he was destined to pursue a career in the wine business. His father was an avid home winemaker and Mike was fascinated by the process and would often help his dad. For Mike, this became his calling, a life-long ambition that began in the family garage. There, Mike would take any fruit he could get his hands on and craft it into wine.  While just a sophomore in high school, Mike declared his intentions to major in enology at UC Davis, the Princeton of winemaking.
