* I really don't like brewing/drinking beers over 6% ABV. I just can't really stand Belgian beers and I am not much of a fan of sours - even though I have "tried" to like both.
* I think an awful lot of brewers spend too much time blaming problems on abstract brewing process when the real problem is the fact that they don't do a good enough job with sanitation.
* Water matters - a lot. It should be something a brewer pays attention to right from the first batch (as simple as just using RO water). Too many people tell beginners that adjusting water is "hard" and they should worry about it later.... no - they should do it right from the very beginning. Tap water with chlorine will ruin beer. Very hard water can ruin beer. It just is not hard to make sure that component is correct, or in the ball park. It is a disservice to convince so many people it is "difficult" when it isn't.
*The purpose of home brewing, as a hobby, is not to save money. It is a hobby.... like other hobbies. I have always found it odd that home brewing is one of the few hobbies where a fair number of people almost look down on those who spend money on nice things for the enjoyment of their hobby. No one bashes on golfers for getting a nice set of clubs, or a hunter for getting a great new gun...... but, it seems that often (not always) when someone gets something nice, lots of people can be quick to point out "that isn't going to make better beer" or "my 30 year old cooler is just as good." I love seeing people go overboard on their brew set up and enjoy building something really nice.
