Scotch Barrel Bungs

Scotland is known and respected across the word for its whisky. Distillery operators are dedicated to perfecting their craft and seek products that help them produce the best scotch possible. Every component of the process is important, from the grains selected to the barrels used for aging. Even the plugs used to seal your barrels are an important consideration.  


Wood plugs are traditionally used as scotch barrel stoppers, but this material is prone to damage, mold, and warping. A better alternative is silicone, which is used across food and beverage applications because of its durability, temperature resistance, and resistance to fungal growth. Silicone whisky barrel bungs are designed to be used over and over without losing their sealing power.
