Calmix is an intense Russian Imperial Stout from Brouwerij Martinus in Groningen. This full-bodied beer marries dark cocoa notes with the spicy heat of Naga Jolokia peppers, delivering an unexpected and layered drinking experience. Despite its strength, it drinks smoothly and carries a rich, dark brown head.

Brewed in the distinctive industrial space on Kostersgang in Groningen's city centre, Calmix embodies the bold approach that defines Martinus. This is a beer for those who embrace intense flavours and welcome a touch of adventure in the glass.
