The quality of a tour depends so much on the person taking you. I've been to Glenmorangie once and got a super local lady of some antiquity who couldn't do enought for us. But my accent is decidedly RP, so perhaps that helps.
I was at Bushmills a couple of weeks ago and it was a very sad experience. There was no production (Saturday) so they cut the tour fee to £4.50 !. We didn't see the inside of any mash tuns or washbacks, although I'm sure we were all glad of the Eamon Holmes video which showed us the spirit safe - for we only saw tha back of it in the distance on the tour. Then we went to a big room with barrels and were invited to inhale the angels' share. There wasn't much aroma, to be honest. I asked whether the barrels had anything in them as I thought it was unusual and foolhardy to store them vertically. The guide, Dolores, confirmed that there was no actual whisky in the room - except in the display bott;e of 12 year old available exclusively in their shop. Then off to the silent bottling plant to see some conveyor belts - and a small dram in the bar. The bar did have some interesting looking bottles but they were not available, either for tasting or purchase. There were bottles of the standard range, but unusually, the tour ticket didn't get you any kind of discount.
I tracked a dram of their 21 year old down to their canteen (£10 a shot in a tumbler) but chose not to buy a bottle as I was so cross with them.
Sorry for the digression. Back to Highland malts...
