Normal-flow, hard plastic free-pour spout with a large-sized amber colored poly-cork for bottles with necks close to 1.1" (29mm) inside diameter. This specialty spout will fit 750ml and liter bottles of 1800 tequila (the old-style bottle with a wide opening not the new screw top bottle that requires a standard clear cork), Cabo Wabo tequila, Rebecca Creek whiskey and other wide-neck bottles. Also can be used on many of the half-gallon and 1.75 liter bottles with large necks. The big bottles that have narrower neck sizes will require the free-pour spouts with the medium red cork. This pourer will empty a liter bottle in 53 seconds. Pour 1 ounce by counting "One One-Thousand One".
