...that old perennial topic.
Going back through my notes from WL (it's amazing how the handwriting evolves throughout the day) I've written two seeming contradictary things about Chill filtering.
Obviously the conceived wisdom of connoisseurs is that chill filtering is a "bad thing" - born out of trying to improve appearance of chilled/diluted whisky and strips out some of the flavour in the process.
In my notes I have reference to the colour and odour of the filter pads after a chill filtering process - proof if ever needed that chill filtering is the devils work!
However on doing a very informative vertical tasting of Old Pulteney with one of their master blenders (sorry didn't make a note of the name) he stated that in a blind taste testing of CF and non-CF whisky of comparable vintage the leading expert (didn't make a note of name again - but possibly MJ) couldn't taste any discernable difference. I stupidly didn't probe him on the scope of this test - was it limited to Old Pulteney, were they from the same casks etc, as he was about to pour the 17YO!
Now to my uneducated palette, non-CF whisky is usually richer / fuller / better. BUT for most familiar distilleries the non-CF expressions are those which tend to be at cask strength from premium / older casks. So the majority of the difference I'm tasting could be attributable to the age / finish.
Does anyone know what test "Old Pulteney" could have been referring to, or has anyone got a reference to a blind taste tend carried out by a whisky "expert" which proves conclusively what Chill Filtering has stripped out.
