It's known how much a cask is important for the maturation of the spirit inside.
Now I was thinking to this:
like every other spirit sherry as well will have different levels of quality,
(I'm not aware of the sherry brands) so I presume there would be great sherries and less good sherries.
So I'd like to know if the quality of the sherry influence consequently the quality of the whisky(the better the sherry the better the whisky)and of course also if the age of the sherry has an impact.
If I'm not wrong sherry have to mature for not less than 3 years (just like whisky) but there are barrels that have contained sherry for more and more years, so maybe this will change the impact on the whisky.
So I'd like to know if the best sherry casks are the ones that have contained the highest quality sherry and for more time (or if age has not great impact on subsequent whisky maturation) or if there are other factors to be considered to term a sherry cask a good sherry cask.
I'll be very grateful if someone could spare some light on these arguments and help me to understand better.
