# Where did the description that acids are sour and bases are bitter come from?

Where did the description that acids are sour and bases are bitter come from? With Arrhenius definition, those descriptions may have fit acids and bases, but with the Lewis definition, I guess they would not really apply.

For example, $\ce{AlCl3}$, a known Lewis acid, does not taste sour but rather "gives water a bitter astringent taste" as stated by PubChem in this link.
