Tasting thousands of wines each year is a treat, a thrill, a blast. But it does have its problems. First of all, it gets you drunk. You're not supposed to say that, but Steven Spurrier, he of the the (in)famous 1976 Paris tasting when Californian wines trounced the French opposition, estimates that in tasting season, he has two bottles of wine per day. Those folk who intend to drive after any tasting of more than 20 wines - they're just daft.
But another hazard involves the mouth. Red wines leave you with a Draculine grin, with purple lips, black tongue and teeth a dubious shade of grey-y crimson. While this means that you never have a problem getting a seat on the Tube - one grimace, and the commuters flee - it isn't exactly the most endearing of appearances.
So what do you do about it? Some people brush their teeth straight after the tasting - no, No, NO!!! That is, not unless you want to strip off all that enamel that the wine has kindly softened, and leave your teeth even more vulnerable. Do not brush for at least a couple of hours, Instead, chew some gum and produce some acid-neutralising saliva. You'll look like a chav for a bit, but you'll still have your gnashers.
And if you have any teeth that 'sing' when anything too cold/too hot/too whatever hits them, then invest in some Colgate Fluorigard Gel-Kam. It's a fluoride paste that you smear on your teeth after brushing, swish around for a minute or so and then spit out without rinsing (you should never rinse after brushing anyway). I've just reordered my supplies from Smiles Unlimited in Appledore. My dentist commended me last week for my excellent oral hygiene - her comment now appears on my CV.
A final suggestion. Get a tongue scraper. Mine's a metal contraption that I use whenever my tongue feels furred up - the gunk you get off is disturbing, but your mouth feels (and smells) a whole lot better for it.
