Review on Globe Shaped Whiskey Decanter - Premium Liquor, Scotch, Bourbon, Vodka or Wine Flask - 850ml Capacity by Alex Pollard

It will definitely fit a full 750ml bottle of your choice with some room. I gave a full 5 stars because it is exactly what it says it is. They just never expect it to be the size it really is. I would buy it again but it's really nice. UPDATE: After using it once (literally opening the valve once) it started leaking. Teflon or whatever is used in the gasket will not seal properly. Luckily I had a glass underneath because a whopping 12 ounces of liquid came out overnight. I've tried cleaning, disassembling and checking for dirt but nothing. Even tried the water to see if there was a difference. But no! This is a great topic for discussion in the bar, but DO NOT REALLY USE it. I am not happy with my purchase and would not recommend it to anyone.
