Sourdough on Rue de Buzenval
Boulangerie Bio : Les Voisins is an independent organic bakery on Rue de Buzenval in Charonne. Step inside and the bread does the talking: long-fermented sourdoughs, a thick crisp crust, a light airy crumb.
The croissant is the one to buy first, made with sourdough and plenty of butter, soft and chewy inside with a crisp shell. The pain au chocolat gets the same treatment. On the sweet side, the lemon cake comes by the slice or whole, and the custard tart and apple turnovers fill out the pastry counter.
Among the loaves, the smoky malted barley sourdough is the one that brings people back, and the house country loaf anchors the range with a thick crust. The seeded and multigrain breads are the practical buy: grain-flecked, they hold up for a week wrapped in a tea towel, which is the argument for the price.
The cheapest loaf is still over €4, and it has large holes that make it awkward for toast. The other loaves cost around twice as much.
The counter service is warm and the advice helpful, and the shop keeps organic ingredients sourced locally where possible. It is a small place with a narrow focus, and it rewards buying the loaves and pastries it does best.

Butter-forward, soft and chewy from the sourdough, with a crisp shell.

The pick list
What to bring home
Sourdough croissant
Butter-forward croissants with a soft, chewy sourdough crumb and a crisp shell, made with sourdough and high-quality butter.
Lemon cake
Sold by the slice or whole, this is the sweet that gets singled out most often.
Smoky malted barley sourdough
A distinctive dark loaf with a smoked malt flavour that is the reason to come back.
Seeded and multigrain loaves
Grain-flecked breads that keep well for a week, which is worth weighing against the price.
Pain au chocolat
The chocolate pastry earns the same enthusiasm as the croissants.
Who is this for
Anyone who plans a picnic around a loaf rather than a sandwich will find the seeded and multigrain breads easy to carry. A curious browser who likes to taste one thing at a time can work through the pastry counter slice by slice. And if you are staying nearby in Charonne, the smoky malted barley sourdough is worth building a morning around.
If you need a late-evening run for everyday provisions rather than a loaf to keep, Supermarché G20 on Rue des immeubles Industriels stays open until 9:30pm most evenings, including Saturdays.
The verdict
The bread is worth the trip, but the cheapest loaf is over €4 while the loaves worth having cost around twice that, so it suits anyone who will pay for a week's keeping bread rather than a budget loaf.
