My two pennies worth is they'll be having to re move the stock (1979 stock at least) into some inactive casks quite soon, this year the oak was pretty noticeable.
My speculation on stock (side chat with diageo guy) is there is there is enough for PE12, PE13 and probably PE14 but don't expect a PE16 and hard to say on PE15. Pointless info though as by PE13 we'll know if the release numbers drop to 1,500 as they have for Brora - which the independents seem to have run out of near enough and diageo don't seem to have in abundance either.
