Alchemist Dreams

Piloted by a recession-stricken Londoner with a chemistry degree, AD uses an online interface to allow customers to create bespoke bar-fillers: start with a neutral grain spirit, then choose from half a dozen base flavours (orange, lime, fig, etc, or just "no fruit"), and 18 different "accents" including allegedly psychotropic wormwood, Szechuan pepper, coffee, basil, cloves, and even red cinchona bark that when exposed to UV will glow blue -- so assuming your date doesn't run screaming when you throw on a black light, she'll be very impressed.
