Winery Management & Development Company

Proven, Full Service Solutions for Winery and Restaurant Development and Management

let's start at the beginning…

Temecula Valley Winery Management (TVWM) is a full service winery management and development company. Through years of industry experience TVWM has developed best practices in winery management and viticulture that give clients a tremendous advantage over winery competitors. We aim to be our client's biggest asset and truly take ownership of each individual project.

TVWM was formed as a coalition of companies which originated with our parent company Stage Ranch Farm Management, Inc. Stage Ranch was founded in 1972 by Gary Winder and was joined by Mike Rennie in the early 1990's. Stage Ranch gained a reputation for being a high quality farming operation and prides itself on its ability to meet a wide variety of property owner's demands. It is currently one of the largest farming operators in Temecula and farms approximately 1,500 acres of wine grapes, avocado and citrus, all located within a 50 mile radius of the Temecula Valley Wine Country.

Stage Ranch is a vital part of TVWM's ongoing vineyard development and viticulture program, as they are the exclusive provider of TVWM's farming services. The viticulture practices used are state of the art and have yielded a large portion of Temecula's most highly acclaimed wines, including several 90+ point red wine scores with major wine trade publications such as Wine Enthusiast Magazine.

After the success of its first winery development project, Leoness Cellars, TVWM's Management Team further developed standards for the construction, development, branding and operations of future winery projects.

Planning and Project Development

This element is vital to the success of a project and requires the ownership and management team to go through a series of planning exercises developed by TVWM to best establish its financial and operational goals. Rigid, county imposed development standards, inflated costs and other factors can cause a project harm from the outset. Managing the development cost to not exceed the properties revenue potential is vital. A "boots on the ground" approach and heavy involvement on the county level has led to us managing this successfully.

We truly believe that our people are our greatest asset and that good character, a high level of competency and a sincere respect among our management and employee groups are vital to the success of building a world class brand and winery.
The following is a summary of the people who make up our organization:

Rebaux Steyn

Temecula Valley Winery Management – CEO, Co-Owner

After graduating with a degree in systems engineering in Port Elizabeth, South Africa, Rebaux relocated to the United States. He became involved in the family business in 2002, starting with the development of Leoness Cellars. Together with Mike Rennie and Tim Kramer, they constructed the Leoness infrastructure, including branding, operations and best practices all the while securing and developing the financials.

During the process of developing Leoness Cellars and with its immediate success came requests from prospective winery developers to consult on their product development and winery management.

To accommodate this change in business Rebaux founded Temecula Valley Winery Management (TVWM). TVWM has become a driver of new winery and product development in the Temecula Valley. Rebaux's primary focus is currently on the daily operations of TVWM and the development of new winery projects in the Southern California region.

His passion led him to work under some of the best winemakers in Southern California, including Jon McPherson (former Winemaker for Thornton Winery) and the winemaking team at Callaway Winery. Tim was instrumental in the development of the Leoness Cellars brand, and in 2008, he co-founded Temecula Valley Winery Management.

It did not take long for Tim's winemaking talent to leave a big mark on the Temecula Region. In the last 10 years, Tim has received dozens of 90+ Point scores on wines produced for Leoness Cellars and other TVWM clients, making him the only winemaker in Temecula history to have received as many. (Ratings received from Wine Enthusiast Magazine and Connoisseurs Guide of California.) He and his winemaking team have also won numerous Gold, Double Gold and "Best in Class" awards from national and international competitions, including the San Francisco International Wine Competition.
