Dieu Du Ciel! and La Barberie have been united by the same passion for 25 years already. To celebrate, we decided to brew a porter. A porter that we fermented in old Solstice d'Hiver barrels. Barrels that have been pierced everywhere, to connect them with pipes. Full of pipes. In short, we made a Burton Union System. It's complicated, but it was above all an excuse to have a good time together.
