He's a high-performing mixologist who's travelled the world plying his craft and winning awards. He's taken the latest thinking back to the fast-developing mixology scene in Berlin.
Andreas runs the Alto Bar in Adina Apartment Hotel, built less than five years ago, rising from what was a scruffy carpark for Trabants and Ladas in former East Germany.
Its bar is all very new Berlin cool and, with an emphasis on spirits (it has just five beers), it does brisk trade with Antipodean families and Brits on bachelor weekends.
Andreas' parents moved to the Dusseldorf area from Greece well before he was born in 1983. He's passionate about mixology - blending, infusing, straining, squeezing, barrel- and bottle-ageing a huge range of herbs, fruit, spices and liquor into an 85-drink menu.
Although the bar has a limited number of beers, it has 15 gins in what Andreas says is a gin-and-tonic town.
I got a taste of one of his gin recipe drinks: Beefeater with thyme and infused with orange peel and had a tall glass of what he recommended as a post-ride lifter - the Alto Spritz, (Aperol, soda, sparkling wine and grapefruit).
It's quiet in the bar. Berlin is suffering a post-football final hangover and many have been scared out of town by the city's massive annual bike ride that day. Andreas says, typically, hotel guests have one or two cocktails before heading around the corner to the lively Hackescher Markt near the Spree River.
The stag-night revellers hire beer bikes - contraptions for up to 16 people to chug away on while pedalling something that looks like a small bus - or are whisked away in limousines. On certain weekends, Swedes and Norwegians descend on his place - top-end drinks are cheap here compared to heavily taxed liquor at home - and they typically make an early start, hitting it hard just after lunch.
Alto's Teatime is served in a tea cup but is not your average cuppa. It too is gin-based, infused with ginger and camomile. That's the other thing: the range of glasses, cups and jars. Unlike the big hot chains, he's not constrained by what he mixes or what they're served in.
The bar features 20 types of bitters, a few homemade. The herb-based drinks were originally developed in Africa to ward off malaria, Andreas tells me. He's a perfectionist. His ice cubes must be large and double frozen, the second time to -22C to ensure they melt very slowly in a drink. He says don't worry about mixing different kinds of drinks. The best way to avoid a hangover is to ensure you drink plenty of water and only good quality liquor.
