How to rouse yeast fix stuck fermentation

Watch in HD. yeast attenuation. Find out the percentage of yeast attenuation that the yeast you are using has. Say 72% you take your original gravity 1.062 remove the 1.0 from it leaving you with a 62 - 72% from it =44.64 (round up) now take 62-45=17 then add the 1.0 to it so your final gravity should be around 1.017. So if i checked my gravity with a hydrometer for a couple days in a row and it was higher then this number then i would rouse the yeast to help get it down.

where did ya get the beer balls, to they work at 5280 feet?

@immolateus They dont really work very well. I'm disappointed that i purchased them.

@ciphyre i made a video for you!

@moedogger21 Ok I figured out what I was originally missing, its 62-(62x.72), which would be 62-44.64 or 62-45=17 = 1.017, now I get it....back to some more Two Brothers Cane and Ebel....lol

@ciphyre i made a mistake on my last answer to u the 44.64 is not a percent its 62 (not percent) minus 72% equals 44.64 (not percent)

[ciphyre]

@moedogger21 LOL, doh, I knew the 1.062 SG/OG was from your batch and the 72% yeast attenuation was for your particular yeast strain, the actual math is what is alluding me, how did you come up with 44.64%? I am prolly making the mistake of taking 62-72% at face value but wouldn't that be 10%?

[moedogger21]

@ciphyre the 62 is from the 1.062 SG/OG just take the 1.0 off it leaving me not you with a 62 now minus the yeast attention from it mine was 72% so thats where 62-72%= 44.64% now i rounded up to 45 and took the OG 62 then minus 45 = 17 make my final gravity a minimum of 1.017. did that help? let me know if it didnt or just use the cheating link i sent.

[ciphyre]

@moedogger21 Maybe its because I just did the gravity reading and sample of my first two brews but the math above doesn't make sense to me... 62-72 % = 44.64 huh?

[moedogger21]

@sjporr yeah it works great.

I've done the same thing with 2 meads I did that had stuck fermentation.
