http://en.wikipedia.org/wiki/Brewing
/Brewing is the production of beer through steeping a starch source (commonly cereal grains) in water/
/Brewing specifically refers to the process of steeping, such as with making tea, sake, and soy sauce. Technically, wine and cider aren't brewed but rather vinted, as the entire fruit is pressed, and then the liquid extracted. Mead is also not technically brewed, as the honey is used entirely, as opposed to being steeped in water./
As I said, to each their own, I can see the merits of making beer from a can if you have limited time, knowledge, aptitude or equipment. Good on those who use a can of hopped malt with added extras, and in fact I'm going to show someone a process involving what I imagine is termed kits & bits before showing them how to actually brew, something they think they will do in the long term.
I don't intend to argue this point, because IMO there is nothing to argue. Your 'dictionary definitions' of brewing, and caramelisation for that matter, may be at odds with other, more credible sources. Which dictionary are you using?
I'm using the Encyclopedic World Dictionary, Copyright The Hamlyn Publishing Group Limited 1971.
Its quite a large tomb, quite comprehensive.
Brew:
Definition 1 : to make (beer, ale, etc.) from malt, etc., by steeping, boiling, and fermentation.
Definition 4 : to concoct or contrive
If you look up concoct, and not just in my dictionary, it means : to make by combining ingredients, to prepare; make up; contrive
On the whole, I agree that steeping ingredients as on the part of the malt manufacturer is an act of brewing. That does fall under one of the definitions I haven't listed. However I point out that the malt manufacturer is not brewing the beer as I pointed out.
Secondly, using malt extract to produce beer is clearly an act of brewing by dictionary definition.
Wiki is not a definitive source. You cannot present Wiki in a court of law, nor can you use Wiki as a reference for school projects etc. And that Wiki definition is a very simplistic one. I'm just speaking English. I'll be damned if I start speaking Wiki to satisfy the mentality of the likes of Yob.
You've stated that brewing specifically refers to the process of steeping. Yes it does, but that is not a complete definition. And the definition you've provided states its the production of beer. The malt extract producer hasn't produced beer, they've produced malt extract.
And I honestly don't know why its a problem to others if I have a curiosity about how things will turn out if I try them.
