Review (5/5): This is adjustable and that is a must!!
This aerator is great. I collect Italian wines and I've been looking for an aerator that is adjustable. Novello, Merlot, Amarone, and Ripasso wines all require significantly different aeration. Having an adjustable aerator is really key if you want to optimize your experience with your wine. It may seem a little excessive to be that precise, but if you want to enjoy your wine to its fullest, I'd recommend this aerator over some others that only have one setting.
