Bartlein is a refreshing look at barrel making, they have some innovative methods and machinery that are truly on the "cutting edge" of barrel technology. They have an impressive shop, definitely the neatest and cleanest I've seen. Bartlein keeps relatively long shop hours to keep production up, and they are expanding to keep production up and wait times down. The barrel volume wasn't made public, but I can tell you they're making lots of barrels. We keep a repetitive order placed with them so if something is out of stock it may be replenished shortly.
