A few Christmas Day suggestions from Chateau Sunny Dave ...
Aperitif :
A gorgeous Palo Cortado Sherry - dry at first taste and then all sorts of medicinal sweet flavours come through - either sip it neat (my preference) or chuck it over some ice.
Malbec is my red grape of choice at the moment - I can't do any more than recommend my old favourite - it's what I'll have with my Roast Lamb on Christmas Eve :
An unusual French white - don't be put off by the Chardonnay grape - this is much more than that often implies. Very complex almost oriental flavours - one of the few whites that's as good at room temp as chilled.
A good white from Yalumba - viognier has become a bit over exposed recently, with some rather anaemic wines about, but this is a great example of how it should taste - loads of body and a big mouthful of taste. Have it with your Christmas lobster ...
