The 36-inch Dual Zone Wine Column from True Caliber provides dual temperature control to make sure both red and white wines can be preserved at their respective optimal serving and maturation temperatures. The columns are composed of 300-series stainless steel both inside and out with 15 shelves that hold up to 179 standard-sized wine bottles. The interiors also feature proprietary TruLumina LED lighting with 14 ambient color options to illuminate the bottles. The doors are fitted with a double-paned, UV-tinted glass to protect the bottles from harsh lighting.
