Vodka. (50 million Russians can't be wrong) There are a lot of good ones, but my favorites are Reyka, Level, Chopin, Kettle One, and for a little bite Stolichnaya. Ultralight on the vermouth, or sweetened lime juice. Most bartenders are way to heavy handed when it comes to mixing a martini or gimlet. I use cheap vodka in Bloody Mary's, the mix kills any quality vodka.

Good morning Dave, I've checked the ships systems, and everything appears to be running normally.
