This is a long-awaited book from Roger Protz, a highly respected authority on beer, on the rebirth of IPA or India Pale Ale - one of the most popular styles in today's craft beer revolution. Around the world, young brewers, with passion, reverence and commitment, are bringing flavour back to beer after decades of domination by global giants and their bland products. Such is the fervour for IPA that the journey started by India Pale Ale in Victorian England is far from over.
