Overview & background
In premium spirits, the bottle does a lot of the selling, and weight signals quality. A heavy-base decanter concentrates glass in a thick base — sometimes a 'sham' or false bottom — so the bottle feels solid and planted on the shelf and the bar. The clarity of extra-flint glass shows off the spirit's color.
These bottles blur the line between packaging and barware: many are kept and displayed after the spirit is gone, which is part of their value.
