I did this earlier this year with a 1911-style Martini recipe (from the Knickerbocker Hotel in NYC) and could tell the difference. A fellow Martini nut did it with Vespers and he managed to tell the difference. The problem is that to do these properly is quite expensive and being fairly strong, you're probably not going to manage more than two or three of them if you're lucky. To give you an idea if it's done properly you can actually see the difference. Stirred Martinis take longer to cool and are more watery. Shaken Martinis get little ice particles forming in the drink, making them look a little cloudy.
