The flavours are nice & sweet and they work well together and being honest it does improve with time in the glass so as with many whisky you need to give it enough time to shine.
Like just about every grain that I have had (even the best aged grains) it lacks an extra dimension that some single malts have and the better blends.
Many will disagree I am sure but generally. I am not a fan of grains, this old Invergordon will not change my mind.
It is not unpleasant or tasty, just not my thing so I cannot get near some of the high scores here.
