Jason's Italian Job

Just why do we drink so much prosecco and why is Victoria Moore, from the Telegraph, 'getting back into it'? What do Stanley Tucci and David Tennant have in common? How do you prounounce 'Roncaglie'? And is there any justifiably good reason why every pub' in the land wants to sell you a large Pinot Grigio? In this Italian edition of Adventures In Wine, Jason Yapp, our Godfather of the grape, turns his back on his beloved France to drag David, his uncomplaining consigliare, all the way to Sicily, by way of the Dolomites, to answer all of these questions and more - without blowing the bloody fridge doors off.
