Substance Café is on Rue Dussoubs, a quiet street in the 2nd arrondissement near Montorgueil in central Paris. Five seats face a long counter, the roaster is visible at the back and there is no music competing with the conversation. Book a tasting if you want to drink coffee here. Walk in if you are just buying beans.
Coffee
Joachim Morceau roasts the coffees and prepares the drinks at the shared counter. The café uses a two-group Slayer for espresso and roasts on the Loring S7 at the back of the room. Espresso and milk drinks sit alongside a changing list of rarer coffees, some kept frozen in individual portions. Tell him what kinds of coffee you enjoy and the price range you have in mind. A first espresso gives you a reference point before you decide whether to try a more unusual coffee or order another preparation.
Filter
A V60 lets you follow one coffee from the recipe through to the cup. If you want a more guided visit, ask for the omakase. The operator describes it as a tasting shaped around your preferences, so the sensible first step is to tell the barista what flavours or drinks you usually choose. The format gives you time to compare cups and to ask how origin and preparation affect what you taste.
Food
Plan to eat before or after the tasting. There is no pastry case or takeaway drink service here. The booking page asks each seated guest to take part in the coffee experience, and lists caffeinated drinks and cow’s milk. It is a better visit with a companion who also wants to taste coffee than with someone looking for a wider café menu.
Service & Room
The small group shares the countertop with the brewing station. You can see the drinks being made and hear the explanation without needing to move around the room. Book online when the date comes into range. The reservation page opens bookings seven days ahead and carries the current tasting times. Give yourself enough time after your slot if you want to browse beans or ask about brewing one of the coffees at home.
