I've Colin Field to thank for my French 75 epiphany. One evening in early June 2017 I was sat at his bar (Bar Hemingway) and he showed me the vintage 75ml...
Quite a different beast from the ‘classic’ 80s/90s rendition of French 75. The usual version is light and bright gin n fizz, this is much more sophisticated and grown up, almost malty. Had some homemade grenadine that I’d received as a present, which was much less sweet and needed doubling. Will try with regular commercial next time to compare.
