Red Caboose Winery  Designing a GREEN Winery Solar Power Geothermal Chilling Rainwater Harvesting At Red Caboose Winery we are interested in more than traditional winery design. Our winery incorporates sustainability design principles, including: gravity wine flow, solar PV electricity panels on roof, geothermal chilling and cooling, geothermal chilling of white wines, capturing rainwater from our roof for irrigation, and using sustainable materials. All of these fundamental design principles translate to energy efficiency and cost savings.
