basically the cost of the book anyway to help this guy get his project off the ground https://www.kickstarter.com/projects/kiwicraft/kiwi-craft get on it!!
most if not all of this information is available online already for free is it not? if they can get a publisher and do a run in their own right then good luck to them, I've bought some books in this style previously. This sort of project does not warrant a kickstarter however in my opinion. If it was some awesome brewer opening a brewery and promising beers down the track however, I would consider it...
