Double magnum bottle
These wines are in a 3-liter bottle, known as a Double Magnum. The size of a Double Magnum is ideal for family celebrations or other significant events. It is equivalent to 2 Magnum bottles or 4 standard bottles.
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, which is specifically intended for wines meant for extended aging. In some cases, the closures are also sealed with wax.
