Max stocks the shelves at Zero Dosage with wines from Germany, Austria, Spain, France, Italy and Slovenia. Because his interest in natural wine reflects an eco-friendly approach, he doesn’t see the point of importing wine from as far as South America, for example. His philosophy is to be approachable. When he makes recommendations to customers, Max says, “I try to find wines that are drinkable and fun. It should not be for craziness sake that I have a certain wine in the shop.” Every Friday, Max organizes a tasting of four wines for €15 to €16 (£13-£14) at Zero Dosage, and for those interested in expanding their knowledge, he offers small, intimate workshops on natural wine that run for about two and a half hours.
