Hello everybody,

Brewed a Porter and a Milk Stout with 2 different Yeast fermented at same temps

Actual brew day specs: 1.060 post boil gravity

Fermentation setting temp: 65F

1 week later>>>>>
Actual Samples/ hydrometer reading
Date:  01.08.2015
Sample temp: 65F
Gravity: 1.020
Apperrent Attenuation: 66%

Vs

Brew Date: 01.01.2016
Milk Stout (no lactose yet)  5.5 gallons
Yeast: WLP002
Recipe O.G: 1.058 & F.G: 1.020
Actual brew day specs: 1.060 post boil gravity

Fermentation setting temp: 65F

1 week later>>>>>
Actual Samples/ hydrometer reading
Date:  01.08.2015
Sample temp: 65F
Gravity: 1.021/22
Apperrent Attenuation: 62%

Ok so last night 01.08.2016 Around 9pm. After these readings I raised the temp from 65 to 68F via temp controller
I figured a slow temp rise thoroughly the night..

Today, Saturday Im going to raise up to 71F  by this afternoon

I have to leave out of town for a week by Sunday night..
Can I leave it at 71F the entire weekend plus the week till I get back on Friday night...????

Sure.

Mr Denny, sir
Thanks for your answer..will adjust the temp today to 71F and leave till next Friday :)

Question,

I know Yeasts do what they want to do..
With that said,  I never used Dennys yeast...is that apparent attenuation in ball park..?

Guess I'm asking because when I used other Yeast like wlp001 that stuff chews right through the Wort in like 3 to 5 days..

I know different strains... But I'd thought I'd ask you..or anybody who has way more experience..

By the way I tasted the starters with the different Yeast..Dennys and WLP002

Starter tastings..LOL hey I was curious and impatient!
The Dennys was almost crisp but soft..kinda malty...very nice   can't wait to keg the Porter!
This Yeast is like 1056 but softer and maltier

The WLP002
Was fuller..more soft. A bit more Malty but not by a mile


Hmm can't wait to keg these!

You're in the ballpark for a week in on a first pitch. I get anywhere from 68-82% with it depending on wort composition and yeast generation.

fwiw, 002, you really need to start ramping up the temperature about 48-72 hours after fermentation has begun - its a fast fermenter and one that wants to go to sleep quickly and you need to keep it going by raising the temp before it has a chance to do that.  my last batch with 002, I got 77% attenuation.

you may be able to get it going again a week after to squeeze out more points, but I wouldn't be shocked if its only 2-3 more. 

keep in mind, the lactose may cause a higher FG than the same grain bill sans lactose.

Blatz,
