Review on Ameripour Speed Pourer: 100% USA Made Patron 🍸 Pour Spout for Leak-Free, Smooth Cocktail Pouring - Clear by Aaron Vang

Largest hole it will fit is a 1-1/8" hole. I know it works for 4 oz Patron Tequila, 4 oz Cazul Tequila, and 4 oz Kirland Brand (Costco) Tequila; so possibly every 1.75 liter bottle of alcohol. I love my Ameripur, it works fantastic, no more spills when I pour. To clean, simply run water through each hole, then squeeze soapy water on each end and run water through each end again to clean. To make sure all the water is out I then rock it a few times on both ends on the folded towel and then let it dry completely overnight.
