What is the largest single bottle of liquor?

It's difficult to definitively say what the absolute largest single bottle of liquor ever produced is. There are several contenders, and the definition of "single bottle" can be a bit fuzzy.

Here are some examples:

* The "Midas" bottle of Johnnie Walker Blue Label: This 3-liter bottle, shaped like a giant gold coin, holds 101 standard bottles of Johnnie Walker Blue Label and is considered the largest single bottle of Scotch whisky.

* The "Giant" bottle of Hennessy Cognac: This 15-liter bottle, standing over 3 feet tall, holds about 40 standard bottles of Hennessy Cognac.

* The "Double Magnum" of wine: This 3-liter bottle is common for high-end wines and can be considered a single bottle, although it holds multiple standard bottles.

There are also custom-made bottles of various sizes, potentially exceeding even the "Giant" bottle. However, these are often created as one-off pieces and may not be widely available.

Ultimately, the "largest single bottle of liquor" is a matter of interpretation and depends on the specific criteria used.
