Days ago i sent an email to SG customs checkpoint, It's abt bringing a bottle of 700ml sealed whiskey & another 300ml whiskey left over from a 700ml bottle. Their reply was you may combine the amounts of whiskey in both sealed and unsealed bottles as long as both are within the one litre limit. All the while i have to force myself to finish the whole bottle by the end of the trip but now i can purposely left it with or lesser than 300ml. Anyone here tasted all four kind from Yamazaki distiller reserve? Which is the most popular one?
