Answer:

#"Bitterness"# is probably a chemical property......

Explanation:

See this old answer and links. And thus bitterness probably relates to the #pH#, with #pH>7# giving a soapy, bitter flavour. Note that we commonly drink #"bitter beer"#, in Old Blighty it is common to order to pint of bitter in a pub. Beer, like wine, and cheese, and lemon juice, and most things that taste good, is slightly acidic.....
