OK, OK, I meant silver-haired old ladies who play bingo and eat Lean Cuisine.
Really, if you're going to appeal to a wine-educated crowd-GREAT! I've just had dealings with the everyday/layman's sort, I suppose. Weddings are memorable for many reasons and rarely what sort of bubbly is served for the toast. At that special moment, few will taste the selection, the speech is what matters.
Don't get me wrong, if you have the green, go for the best!
