How much wort should be left in the brew pot?

The strategy for getting the most wort into the fermenter is to dump it all in. Everything, hops and everything. I don't scrape the stickies off the wall of the pot, but I tip the whole thing into ...

How much will initial oxygen in wort affect final alcohol in beer?

"This means that the initial metabolism will be aerobic. Aerobic metabolism of sugar yields no alcohol, but still reduces the gravity." Well, actually this isn't true in virtually all fermentation ...

Does the amount of Diastatic Power of the grains influence the alcohol content of the beer?

Diastatic power should not affect alcohol content, if it's enough. If iodine test came out negative, and there is no unconverted starch, you got all the sugars that was possible. Only if diastatic ...

Best way to rack to fermenter

Pretty much. Either the strainer will strain the hop material, and clog, as you say, or you can use hop bags or a hop spider to do the filtering. Other methods involve whirlpooling in the kettle to ...

How can I determine why some all-grain wort is cloudy and if I should do anything about it?

It could be many things at this point. It may just be happy yeast in suspension. But sounds more like the hot break and cold break proteins are still in the wort. They should drop out after ...

Does the amount of Diastatic Power of the grains influence the alcohol content of the beer?

Diastatic power is basically how much natural enzyme is in the grain. You need an average of 30°L per pound of grain for complete conversion of starches. So yes it does play a role in how much ...
