Ok so I have been an extract and specialty grains and partial mash (probably only in my mind) brewer. I have 24 batches under my belt for the last year and a half. I have most of the equipment to go all grain need a bigger kettle and a propane burner to be ready. I recently purchased Gordon Strongs book "Brewing Better Beer". After reading some of this it makes me reevaluate my situation. Do I NEED ph measurements, efficiency calculations, the water treatment chemicals, and countless other things that are mentioned in this book ,which I readily admit that is above and beyond my skill level, to make good beer or should I just go for it and learn the hard way or hold off till I have the money to get the equipment I need? My personality doesn't allow me to jump into something if I am not prepared. Just looking for some advice on whether to try a simple first all grain and enjoy it or wait for more equipment.
