(unfortunately I had no sweet vermouth so I used Lillet instead)
Took a day trip to NYC with my father yesterday to have Father's Day dinner at Firebird. Tasted quite a number of vodkas. Ate some caviar. Thoroughly enjoyed an apparently cheap but hard to find Russian brand called Putinka Reserve. Good stuff. Going to get some and compare to my beloved old style Smirnoff Black.
They had a brand that was supposedly filtered through diamond dust because it is a 'better' form of carbon. Now that is the stupidest shit I have ever heard.
