I tried the 2009 Rosemount Show Reserve Chardonnay on an aeroplane. What a shocker this is. Rosemount used to have access to a vast amount of Chardonnay, and some were reasonable. I have not had any of their wines for a while and don't know the current circumstances.
In any event, this wine is as industrial as you can get: no particular fruit flavour, very oaky, slightly sweet. It screems 'pump out the volume' and 'enjoy the alcohol, no matter what the taste'.
PS: I just saw this wine advertised in a merchant's brochure: oaky is 'toasty' and what I called 'no particular fruit flavour' is 'straw and melon finish'. Hilarious!
