When I drink Gin I like Hendricks.
I like gin just about as well as I like bourbon, although living in a control state means I'm mostly limited to the mainstream brands. Gin sharpens my appetite as no other distilled spirit can, so I particularly enjoy a couple fingers before dinner. I drink it on the rocks, usually with a couple olives.
Plymouth is probably my favorite brand, although I can't get it here, so I most often buy Tanqueray. The two brands I have open at the moment are Beefeater and Hendrick's.
I had some Knickerbocker Gin from New Holland last night, and really loved it. I've also been enjoying Ransom Old Tom Gin. Barrel aged and a nice twist for me.
I like Seagram's Distiller's Reserve 102. Cheap, tasty, and effective.
Regular Seagram's doesn't do much for me.
Seconded on the Seagram's Distiller's Reserve, along with Beefeaters. I like Broker's, too. 80 proof gin won't do.
I can drink many different gins, but my favorite is Bombay Saphire, especially in a Martini.
