I know, sounds like a cheap science fiction novel. But really, what's the normal ratio/relation between OG and FG. Most of my beers have finished at about 1.010. I'm ready to bottle a beer that was mashed at a very high temp - 160F and recipe says FG shoulod be 1.018 - 1.020.

If my OG started at 1.058, have I finished fermenting if I'm sitting at 1.020?

Any science fiction brewers input will be welcome.

Thanks.

Somewhere between 10 and 35% of OG for beer. Depending on the yeast, the recipe, the mash temperature, decoctions, etc.

It's finished if it has been at 1.020 for 3-4 days.
