[quote=waterboy]Does a device such as the Vinturi Essential Wine Aerator really do much, or will you taste a huge difference in decanting for an hour?[/quote]
I use the Vinturi into a decantour and I think it makes a huge difference. Really opens up the wine.
As for the cheap wine thing.
Try Layer Cake. Commonly availalbe for 12 to 18 dollars a bottle. FANTASTIC for the price! Really gotta try it but I only make the recommendation for thier Primitivo, Malbec, and Cab. The others taste a bit cheap to me.
