So disappointed. It's DH's birthday today and I wanted to make it really special for him. Got smoked salmon and scrambled eggs on muffins for breakfast and bought a bottle of sparkling wine to make Buck's Fizz as an extra-special treat. When I opened it, there was a big chunk missing from the end of the cork and it gave a very feeble 'pff' instead of a big pop. Flat as pancake! I will be taking it back to Sainsbury today but it spoiled the special birthday breakfast I had planned .
