The world’s spirits are like any one of us. They’ve each got their likes and dislikes, and their friends and enemies. Some of them are solitary sorts, not much given to mixing with their peers. Baijiu might be a fascinating and heady spirit when sipped in little (but frequently refilled) thimble-cups, but just try fixing cocktails with it. It even makes a lousy Old Fashioned, and nothing makes a lousy Old Fashioned. Others are utterly, unabashedly promiscuous. That vodka? It’ll mix with anything.
