Imperial bottle
An Imperial bottle is a large wine bottle with a volume of 6 liters. It is equivalent to 8 standard bottles. The size of an Imperial is ideal for medium to large celebrations.
This is a prestigious type of bottle designed for wines with a longer aging potential. The glass is thicker, and a longer cork is used, specifically for wines meant for extended aging. In some cases, the closures are also sealed with wax.
