JonM mentioned that recipes can be scaled (not inherently obvious with anything that involves chemical processes) and one person mentioned a place to buy equipment the remaining 2 pages - 2 posts just made snide unhelpful comments about how absurd it is to think 5 gallons is too much.
Okay, half the comments were gentle and compassionate and friendly and not "snide". But they still approached the problem by discussing what wasn't pertenant and trying to change the OP's opinion rather than simply answering the question asked.
Answering direct questions should always com first.
Discussing opinions and positing alternative point of view second.
Insisting an OP readjust his opinion to suit yours never.
Why? The OP *clearly* said he didn't want to and that he felt it was too much. What he *did* ask for was how to cut the extracts down. For which there is a simple, unambiguous, and utterly undisputed answer: scale the ingredients.
Opinions as to 5 gallons *is* the right amount are irrelevant.
I generally don't like to get into debates about what is the "proper" behavior, but you really need to relax my man. The OP clearly expressed that he thought that 5 gallons was too much because he does not drink that much and was worried that he would get bored with a single beer. Now, many of us attempted to point out that this was false logic because he would not be limited to a single beer. He seemed to be assuming that the typical brewer makes one batch, then waits until he finishes all of the beers from that batch before drinking beers from the next batch. We attempted to point out that this is not the case.
As for your suggestion that we should answer the question first, I disagree. If the premise seems flawed, pointing that out is actually MORE helpful than simply answering the question.
