I always favour advancement and change for the better but if it ain't broke...........!!
It seems to me that unnecessary resource is being directed to an area that need not be tinkered with.
Malt drinkers are invariably seasoned folk who have developed their palate and have a genuine interest in the product. They appreciate blends and vatted malts in their own right and recognise the subtle differences.
New drinkers will usually go for recognised brands and few really distinguish between a blend or single malt until their palate develops.
Do they really need to know that a malt is a blended malt as opposed to a vatted malt? I suggest that this only leads to confuse.
