Not too sure about your comments regarding Lillet being a Vermouth with a coffee flavour. This is an aromatised wine as such not strictly a Vermouth. Also it certainly does not have a coffee flavour. Interestingly the Vesper is often referred to as a Vesper Martini. But as it does not actually contain any Vermouth it can not be described as a Martini at all. Now what makes a perfect Vesper? happy to debate this with anyone as not even Bond had a perfect Vesper neither shaken or stirred!
