Review on 🍸 Premium Liquor Bottle Pourers Set of 6 - 1oz Measured Wine Pourers for Efficient Liquor Dispensing in Home Bars, Perfect for Cocktails, Tequila, Whiskey and More! by Mikey Shook

These bottle pourers are manufactured from hard plastic and stainless steel check valves. The fit and finish is acceptable for this price point, but I ordered a package of four and found that all of them delivered about 3/4 oz or approximately 20 ml instead of the advertised 1 oz. This was with common 80 proof Bacardi rum. The paperwork says they are made to be used with wine. Perhaps they would deliver 1 oz of wine depending on the density, but who drinks wine by the ounce? If you are looking to measure 3/4 oz these may be ok, but they appear useless for measuring 1 oz of common spirits.
