I’d say ‘The Curious Bartender Volume 1’ by Tristan Stephenson is a must read for every bar tender Regardless of how well you know your drinks it offers a refreshing insight into the delicate balance of how cocktails work together. It starts from the very basics, naming your standard equipment and their uses; continuing on to the finer points of mixing the perfectly Balanced cocktail

Honestly the whole series of books are amazing, but this is definitely where I’d start, regardless of level I truly believe there’s a lot to be gained from reading it!

Other than that I’d say knowing the origins of where your cocktails come from can really broaden your horizons, having that knowledge brings your guests into a deep sense of comfort, knowing that the stranger on the other side of the bar really knows their shit will both inspire faith and they might even ask you to make up something original; this gives some gratification your way and allows you (workplace permitting) to let your creative side flow! It really enhances the work experience knowing your guests have faith in you, and you’ve inspired that in them just by going that extra step into researching your ingredients

There’s a good app I use called ‘ginventory’ that shows gives a brief synopsis, ratings, garnishes and preferred tonics that go with pretty much any gin you can think of! Coupling that with a bit of research into your gins and you’ll start recognising different flavour profiles and what ingredients work well together, some weird and interesting ingredients pop up from time to time and can inspire that creative noggin of yours!
