We have to admit that the drug and alcohol content in "I taste a liquor never brewed" is pretty light. However, what Dickinson has to say about inebriation is still important. She seems to be saying that the drunkenness that comes from alcohol is man-made and artificial. Though it's pleasant in some ways, it just can't compare to what can be found out in nature because what we have in nature has been given to us by the greatest bartender of all time: God. As indicated by the final stanza, it pleases those higher beings to see us revel in the natural beauty of the world around us, and thus, by extension, it probably pleases the "big guy" as well.

Chew on This
Foxglove, being a poisonous plant (and not this), is used specifically in the poem to warn against overindulgence, even though the speaker does not seem to heed this warning herself.
Nice try, but it is impossible for the poet to express her feelings through the metaphor of drunkenness if she has never experienced alcoholic inebriation first hand.
