Hi Dean Hill here. I once kept a bottle of Dom champagne I was given as a gift for many years. It traveled with me through several moves, even a marriage. It was already 10 years old when I got it but I waited many more years to pop it. The occasion? I believe it involved lingerie but I’m not sure. It was a sad disappointment. The champers was thick, dark coloured and flavourless. Later I was told that Champagne does have a best before thing. What is 170 year old Champagne like? Find out here.
