I've been brewing for a good few years now and really enjoy creating my own recipes. I have, however, got stuck in a bit of a rut regarding my choice of malts. I use Maris Otter and wheat all the time with the odd bit of Vienna or Crystal here and there. Has anybody come across a thread, a link, a vid or even a book that describes the different malts and how they work in different styles in a bit more detail?
