A Dream of Sestina Gin

There was a bottle of gin on the table of a bar. My daughter had ordered it and I had a beer. The gin bottle had a chart of which particular gin was in each layer of the bottle, and the arrangement of the six gins followed the pattern of the poetic form known as the sestina. Except that it was inexact: I found an error in the second "stanza" of the bottle. My daughter poured me a small shot of the gin into a tall glass, since I hadn't ordered this especially poetic gin. It tasted like ordinary gin to me. As I was waking up I couldn't figure out if the gin was all mingled together (in which case the sestina form was kind of otiose), or whether somehow the bottle itself was divided into discrete layers.
