The beauty of this hobby is that there is always something to learn, with the reward of incremental gains in quality.

Of course, there is no helping some people.

Hi!
There are many forums out there, loads of blogs and thousands of opinions. Sometimes a member may read something elsewhere that is different to what might be called "received knowledge" about brewing and link to it or mention it in a post. Other homebrewers are pushing the boundaries and challenging what might be seen as sacred cows of homebrewing.
It's up to each member to decide whether to accept the ideas put forward and to try them in their own brewing or to reject them out of hand.
As far as science is concerned, I agree - there are basic principles that can't be ignored.

4. The Yeast. (God only knows how many varieties there are; but I don't!)

5. The Fermentation time and temperature. (Again a multiplication of time and temperature.)

6. The Carbonation and Conditioning. (Another multiplication of time and temperature.)

Add on all of the other elements available and most brains will go into meltdown!

May I suggest that:

1. Brewing is a pastime and NOT a scientific experiment.

2. Recommendations on the Forum are just that; and NOT the only way to brew anything.

Please feel free to comment!

You forgot to mention hops! Hundreds of variety's combined and added into the boil in different times and quantities.

I would disagree and say that brewing a batch of beer is almost certainly a science experiment. You make a prediction based on knowledge to mix grains, hops and yeast using specific methods to produce beer, you then evaluate and make a conclusion when you taste that beer. The only difference is that in a lab you would only change one variable at a time, to see how each change affects the final product. However could you imagine how long it would take to do that, you would spend your life and never move on from one type of beer. I thus conclude that we are all scientists just really **** ones.

I wasn't aware that someone explaining what works for them was "dumbing down".

Maybe there should be a section entitled "It Works For Me" where the scientific intricacies of a process are left unstated ...

... and a similar section dedicated to the really smart people on the Forum.

I'm sure that you could come up with a suitable title.

There are too many variables to count and many many of them are beyond the control of home brewers, just keep pushing things in the right direction make beer n don't worry about them.

Feel free to say what works for you, Dutto. Saying 'what works for me' is different than stating something scientifical wrong as a reason for why something goes wrong for others. Asking people not to refer to the science of brewing, is dumbing down.

I suggest a walk is in order.

OK, since Sadfield has a point to make, here, I comment as follows:

Science is essentially an empirical sort of thing in the sense that observations are made and models are constructed to explain those observations.

If the models are useful, in the sense that beyond "explaining" the observations, they enable reliable and repeatable predictions to be made, then that is science.

When the models no longer enable reliable and repeatable predictions to be made, the models are refined.

So, I do support the point that Sadfield makes, as it is essentially scientific.

A close look at some of the threads on this forum (especially and most particularly the shorter ones) will see the scientific method glorified.
