Shame your champagne wasn't good. However ,as it was a gift, perhaps you can be happy with the thought that you didn't waste your money on an expensive snobbish drink.
Don't get me wrong. I enjoy champagne but wouldn't buy a bottle for just Viv and me, when I know that Spanish Carver is made by the same method and costs a fraction of the price; and tastes just as good.
I recall a programme on TV whereby sparkling wines were being put to a test. It was explained that Champagne has bubbles which come from a second fermentation within the bottle and, whilst there are others made by the same method ( Sparkling Vouvray, Carver etc.) there are others (e.g. Asti Spumante.) which have been injected with gas (CO2.) just as is lemonade. Members of the studio audience were then invited to taste samples and a rather well spoken lady said that she would not give any guests in her house the drink which she had sampled; because, in her opinion, it was 'gassed-up wine'. Unfortunately for the lady concerned, she had been given a glass of the most expensive champagne which was being tested at the time.(About 12 years back; �24 a bottle.)
Makes you think about drink!!
Cheers......Ron.( Quite sober at this moment.)
P.S. sense4all may agree......The 2/3 year olds should be o.k. but , to make sure, drink as soon as possible.
