Why does lemon mean inferior?

Why does lemon mean inferior?

Please see this example. The poster uses the word `lemon' in the last
sentence. I understand in a general sense that this is being used to
indicate something bad or more specifically of inferior quality.
Indeed, Roget's Thesaurus shows the following synonyms for lemon: failure,
flop, junk, reject, piece of junk.
It will be interesting to know how lemon came to mean an inferior quality.
As is shown here, it might have something to do with "sucking the juice
out of somebody" or "bad taste left in mouth".
This seems contradictory to me since lemon is fruit with great
nutritional, medicinal and culinary value. Moreover, there are so many
fruits out of which you suck the juice out. And lemon taste is never bad.
But well languages are languages, and not always governed by logic.
