During 10 days a first fermentation occurs, the second one lasts just as long. After filtering, champagne yeast and white rock sugar is added. After that the bottles are turned and shaken to move the yeast around (remuage) and then the yeast is discharged (dégorgement). This is a very complex and time-consuming process, but the result is worth it: brilliant clear and sparkling beer. Brut beer tastes light even though the alcohol value is quite high. A brut beer is a splendid aperitif, ideal for events and dinner parties.
