Howdy,
Got my first batch in the fermenter. Can't wait 'til it's ready to drink! Got a quick question for everybody. I've seen this explained several ways, so I want to make sure I understand what I'm shooting for.
I measured an OG of 1.047 before I pitched my yeasties (WLP005). The wort was at 68F, so the OG shouldn't need to be adjusted (or only by .001, if it does). The yeast, according to whitelabs.com, has an attenuation of 67-74%.
So, here's my "scratch pad" work:
47 * 0.67 = 31.49
47 * 0.74 = 34.78
47 - 31.49 = 15.51
47 - 34.78 = 12.22
Adding the thousand "points" back in gives me 1.01551 and 1.01222. Rounding to 3 places gives 1.016 and 1.012.
So, that means I should expect (assuming all goes well) to have a FG between 1.012 and 1.016 when fermentation is finished? Is that correct?
