I'll sometimes buy something simply because its new to me since after 60 years, there just aren't that many new things. At the market last week noticed Peychaud's Bitters <Peychaud's Bitters - Wikipedia, the free encyclopedia>. A little makes a candy or nut flavor taste a little more complex, a little like a tobacco flavor does. Peychaud's doesn't have a citrus peel taste like Angostura Bitters. Works well in pipe and cigar flavors too. If I was talking about color, I would call it a drabber, making colors less cartoonish. Doesn't have any sugars or oils to clog up atomizers. Works well in light beer as well. A few drops makes it taste more like real beer.
