(Wines&Vines) - From barrels shaped in water to barrels made from acacia wood, from barrels streamlined for red wine fermentation to appellated American oak, winemakers have more barrel options to work with than ever before. In an industry that dates back to the Roman Empire, abundant new product releases may signify that both the wine and cooperage industries are alive and well. Many of these new barrel options are new to the market, and some are still in the trial stages. A few products aren’t slated to launch until the 2012 Unified Wine & Grape Symposium in Sacramento, Calif., in January.
