This is a bit of a rare one, inspired by a German recipe from 1914. It's sold as a mix of leather, black tea, and lavender, but I personally don't think it smells at all like what that description makes me think of. There's no birch tar or quinoline in here that I can detect, and I'm not sure where that black tea is supposed to be, either.
It's clearly Krigler's take on an old-fashioned "oriental". It's got a classic "oriental" mix of patchouli and amber played against a dank green herbal note, so it kind of reminds me of Coromandel. Then, it's also got a fougere on top, so there's a lot of lavender and some musky tobacco-ish tonka filling out the "oriental" mix, as well as some vanilla (think Le Male). This all ends up mixing together to smell kind of like butterscotch pudding mixed with that Le Male tobacco leaf with that dark green oily herbal note lurking in the background, keeping Lieber Gustav from ever really smelling very gourmand.
All in all, I've enjoyed Lieber Gustav, but it's not really my style. Thumbs up for keeping me interested and smelling good (seriously, a mix of Coromandel and Le Male? That's got to be worth a sniff...)
