Double Barrel Cold Smoker Introducing the brand new Misty Gully Double Barrel Cold Smoker. Simple to use in any smoking chamber, hooded BBQ or grill and create your own cold smoking chamber! Professional smoke results in anything by using one or both barrels. Provides up to 5 hours of smoke. Mix and match your woods to create your own unique flavours and aromas. Two barrels burning in close proximity creates double the smoke and slightly faster burn times for added flavour and intensity. Just add wood pellets, light at one or both ends, and start seriously smoking!
