Wholesale Wine Barrel Bungs for California Vineyards

California Wine Barrel Bungs

Central Valley is California’s main “hub” for wine production. More than half of the state’s grapes are grown in this region, including Chenin Blanc, Colombard, Barbera and Chardonnay varieties. Producers of high-quality wine put thought into every part of production, from the grapes selected, to the different barrels used for aging. Even the bungs and plugs used to seal wine barrels are important to ensure taste and quality.  

Silicone barrel bungs are made from FDA-approved, food grade material. They exhibit exceptional sealing properties and can be used numerous times without damage. Wine barrel bung plugs made from silicone also resist mold and will not absorb odors, both of which are essential properties in preserving the quality and flavor of your wine.  


Create a Reliable Seal with Silicone Wine Barrel Bung Plugs

Ace Seal manufactures its wine barrel bung plugs for superior quality and only uses FDA approved food-grade silicone. We designed our silicone barrel plugs to create a tight seal, preventing leakage and contamination that could damage your product during the aging process.  

Our standard plugs come in a natural, translucent-white color and are designed to fit U.S. and French barrels. Each stopper also features manufacture and date code identification.
