I've got this book, I bought it from a perspective of historical interest, more than wanting to glean information from it, and IMO, I think that's how this book should now be viewed. At the time there was very little brewing literature about, Dave Line took the mantle up with this book, and to pour scorn in retrospect....well.
It's been a long time since I've read it, and I'm not going to re-read it for this review, not just yet anyway, but on a quick flick through there's quite a bit of content that's still relevant today, and also a bit that isn't. The majority of the recipes make me cringe with their additions of sugars, though they have their 'place' in some recipes.
I would not advise anyone to buy this book for any other reason than historical comparison, from memory some of the information is confusing and some is just wrong. You'd be much better of buying Graham Wheelers Home Brewing as a modern guide, though even that had errors in the 1st edition...hopefully Graham's corrected the ones I pointed out!
