My last restocking trip included Hadley & Son gin, Peychaud's bitters, and Porto Morgado ten year old tawny port.
Just as important, what to buy? I read reviews but they don't necessarily tell me what I'd like.
I've been conducting blind liquor tastings with a group of like-minded friends for several years. We tackle a different spirit each time; whiskey, vodka, tequila, etc.
I've learned more about what makes a good spirit, at least to my taste, from these tastings, than from anything else. I wrote an article recently for Proof Media, a liquor site, that summarizes how to conduct a simple tasting.

Some of my repeat purchasing decisions have been made from the tastings I've done, and my friends always want a list of the top scoring liquors for their own shopping lists.
