Need opinions! Guest book

What do you guys think about this guest book idea? I really don't want a traditional guest book.. and a friend of mine did this and I thought it was cute. Only problem is wine isn't really a huge theme at my wedding, though there is a small vineyard on the property. Thinking about doing five bottles... 1st, 5th, 10th, 25th and 50th anniversaries... and then we'd smash the bottle on each anniversary and read all the notes inside! LMK what you ladies think! TIA!
