Analysis of I taste a liquor never brewed

I taste a liquor never brewed,
From tankards scooped in pearl;
Not all the vats upon the Rhine
Yield such an alcohol!

Inebriate of air am I,
And debauchee of dew,
Reeling, through endless summer days,
From inns of molten blue.

When the landlord turn the drunken bee
Out of the foxglove's door,
When butterflies renounce their drams,
I shall but drink the more!

Till seraphs swing their snowy hats,
And saints to windows run,
To see the little tippler
Leaning against the sun!
