Sour-tasting (4)

I think it could be either:

Which length description are you looking for?:

acid

I believe this clue is a double definition.

'sour' is the first definition.
(I've seen this before)

'tasting' is the second definition.
(I have seen 'Sour tasting' mean 'acid' so perhaps 'tasting' could also mean 'acid')

(Other definitions for acid that I've seen before include "bad rain" , "Hallucinogenic drug" , "Sour (substance)" , "Sour tasting" , "Sour - type of rain or drop" .)

I've seen this clue in the Newsday, The New York Times and The Independent.
