This means several wineries, each with their own federal permit, alternate the use of the facilities production equipment, such as de-stemmers, presses, blending tanks, bottling lines, forklifts. Each tenant occupies their own designated footprint, provides their own fruit, storage, aging, production and packaging materials, produces their own wine, maintains their own records, and are responsible for their own reporting, labeling and taxes.

Those interested in becoming a tenant must have winery production experience and/or earned their Associates Degree from the Southwest Wine Centers Enology & Viticulture Program, and present a comprehensive 5 year business plan. Reach out to Us , here for an initial consultation and to submit an application. Keep in mind there is limited space at our facility, and the permitting process can take up to 14 months.
