Storing wine safely has been a problem for centuries. Oxygen and microbial contamination can quickly ruin wine. Many solutions have been attempted – from sealed amphora to rubber bladders. Modern wine storage practice employ mainly barrels and metal tanks. All these devices have a critical weakness – they are rigid containers – so there is headspace. Wine loss due to leakage, evaporation, and removal causes air to enter the container creating headspace. The air in the headspace oxidizes the wine. The only remedy is to top-off the containers periodically. This is labor intensive and introduces air into the container. It also greatly increases the risk of microbial contamination. Some techniques such floating head tanks or argon blanketing are used, but these are expensive and prone to failure. “With conventional barrels, there’s always evaporation and the barrel must be topped off,” notes Dr. Vijay Singh. “At Sky Acres Winery, we go from one li
