I like quality champagne ie Ruinart, most vintage stuff, Noble Cuvee etc, when someone else is paying. for standard Non Vintage Brut you may as well buy two bottles of quality something else ie Deutz, Jansz etc. Champagne is over priced IMO.
re your blog, don’t know why you’ve gone on a rant about Prosecco (as well as spelling it wrong) there are also many other sparkling wines from many other countries that are not Champagne, what was your point?
A bottle of Louis Roederer Cristal is about £130 but a bottle of Louis Roederer Brut is only £30. Both are made by the same company, using the same technique, with the same grapes but one has a gold label and a longer shelf life thanks to a clever UV filtering wrapper.
you need to go on a wine course or something
