I just received a free 10ml bottle of Southern Classic, as well. I gave it the cursory sniff, then put it in my steeping place (built-in breadbox) with the cap off. I smelled a strong alcohol smell, reminiscent of my ex-husband's favorite whiskey (not a good thing). So, it changes significantly in 24 hours? Is cap-off the way to go? Have you tried other Halo tobacco flavors? How long do they generally need to steep? I'm liking the Midnight Apple fairly well right from the mailbox, but the jury's still out on the Tiki Juice. I haven't tested my Voodoo or Tribeca yet.
