its a shame I cant put photo,s up. have brought 4 old bottles of whisky home tonight from Mrs Burgess late Grand-fathers home . unfortunately they've all been opened at some-time in the past . "Heatherdale" 70cl has some age ,yet has a barcode on the rear label . ive not heard of this brand ,wonder how old it is ? "Grants" 1 litre also has a barcode on the rear,label looks aged ?? "Teachers" 1 litre again , no barcode , duty free for export only ,this has the old silver coloured measuring top (ive not seen these since 70,s) ?? "Famous Grouse" 1.13 litre (ex-optic style label) ?? trying to date them approx. ,ask me any questions to help ? just want to know when I come to take a "wee dram" wether I am sinking a 20 , 30 ,or 40 year old nip
