‚ÄúGrottenbier‚Äù was created by Master Brewer Pierre Celis. It is an aromatic dark beer with 6.5% alcohol content. In the marl pits in Kanne ( Belgium) and Valkenburg (the Netherlands), deep under the ground, you can taste Grottenbier in a constant temperature of 11¬∞ Celsius. As it is the case with Champagne, the bottles are placed in a ‚Äúpupitre‚Äù which results in an additional fermentation.
This beer has been noted as one of the best "10 present-day beers by beer guru Michael Jackson". Medium bodied and unique, chocolaty bitter-sweet, created by the master brewer Pierre Celis, a dark Speciality beer.
