Cava: Spain's Premium Sparkling Wine

Great for anyone who knows absolutely nothing about wine in general. As vague as a pamphlet you'd be given for free by any wine region. I'd give it the benefit of the doubt and assume it's just not for me and is instead written for gift shops in the Penedes to stock but then I read these infuriating sentences: "Jaume Gramona also told me a story behind the company's sweet cava and why it is a classic that will probably stay on forever in the standard portfolio of the house. It is a very good story indeed and if you have the luck to meet him, perhaps he will tell you the story too". WTF did I buy this book for?
