Didn't have any citrus infused vodkas, so I upped the standard vodka to an ounce and used ~1/4 to 1/2 oz of Italicus. Splendid result.

An unbelievably sensational and refreshing cocktail that is simple enough for adjustment to any strength and preference, but never fails to hit a spot.

I bit the bullet and tried it. I could have gotten a similar result from scooping my bath water.
