Marin Caratan, has become a local legend in Delano, CA, where he settled in 1919. His passion and dedication would turn into a lifelong pursuit for exceptional quality. In 1926, Caratan and his brother planted their ﬁrst vines in the San Joaquin Valley, an ideal area for producing the ﬁnest quality grapes. Their farm soon became known as an inclusive and exceptional place to work.
With a respect for the original founders, Columbine® Vineyards continues to advance this legacy of dedication, hard work, and love. Through stewardship of soil, sustainable growing practices, and a unique breeding program that has brought Holiday® and Milano® varieties to stores, we’ve always looked to the future while honoring the past.
Like the ﬁrst heritage vines planted by the original Caratan family, Columbine Vineyards continues to grow year over year, advancing a legacy of love that can be found in every bunch of our fresh California grapes.
Each year, grapes are carefully selected from vines at the peak of their maturity, skillfully hand-picked by growers seeking the sweetest and freshest grapes our vines can produce.
Our unique breeding program represents decades of investment and training. Over the years, we’ve sprouted varieties known for their flavor and size, including Holiday® grapes.
As winter temperatures begin to drop, the leaves fall off the grapevine and the vine “goes to sleep.” In January, growers begin to carefully select and prune healthy canes (vine branches) that will result in the following summer’s crop.
In mid-March, temperatures gradually begin to rise and the vine senses spring is approaching. The buds on the canes begin to “break” open and the new season’s leaves begin to emerge.
In early May, as the weather continues to warm up, the clusters (grape bunches) begin their flowering stage commonly referred to as “bloom.” Each individual berry on the cluster begins to flower.
In late May, after the berries have begun to grow in size, each cluster is thinned by hand. This ensures that the grape clusters will size and ripen to their fullest potential.
Around thinning time, a grower hand-cuts a strip of wood from around the vine’s trunk, using a specially designed knife. This practice keeps nutrients delivered to the fruit and helps promote size and sweetness.
After ripening in the warm California sun, our first grapes are ready to be harvested in early July. The harvests continue at different times throughout the summer and early fall depending on the variety, always hand-picked for peak freshness.
Columbine® Vineyards was one of the first vineyards to implement drip-irrigation technology.
We are building an inclusive, respectful culture that supports the long-term career development of farm workers.
We have moved from styrofoam to corrugated cardboard for secondary packaging, along with the implementation of a sizable recycling program. We are focused on waste-reduction packaging innovations that also benefit our customers.
We track soil moisture levels to ensure efficient water use. Our soils can hold more water — with more carbon, soil retains more moisture — and technology makes those gains go further.
As a regenerative practice, we protect local wildlife that contributes to a thriving and diverse natural ecosystem. We are Certified Fish Friendly Farmers.
Our reduced-tillage program means less tractor usage in the field and more carbon in the soil. We use solar and electric vehicles for transportation on the farm.
Our integrated and preventative pest control program reduces the need for pesticides.
“Harvesting beautiful, delicious grapes is such a special art, and each step requires a lot of training whether it’s the harvesting, picking, or packing.”
“From developing this variety over 12 years, to all of the work in the fields, to the marketing we put behind it with retailers, it’s always exciting to see people enjoy Holiday® grapes every season.”
