The Glen Grant 5-Year-Old has no value other than the current retail price. As with most "young" single malts, they are normally bottled for the Italian market. I suspect this one was bottled for the Italian market but the label is not readable beyond what's in the bottle. I suspect it is a 70cl ( 700ml ) size.
