Yeast and Fermentation / Strange yeast behavior
« on: October 24, 2014, 12:02:16 AM »
So never really had yeast hang around like this. It just want floc. Mashed at 145 x 45 min rise to 155 for 20 min then mash out. It's an IPA with London ale 1028 yeast. Simple grain bill 88% 2 row, 6% munich10L, 3%dextrine and 3% caramalt. It's been 5 days. Mash PH 5.5. Ca 104ppm, sulfate 180, CL 44. Any thoughts

Yeast and Fermentation / overpitching and attenuation ?
« on: October 09, 2014, 02:18:42 PM »
Do ya think it is possible for a yeast strain to continually under-attenuate if it is over pitched?  I cont to have problems with WLP007 and Wyeast 1968 58 to 60% attenuation.  Very frustrating every time i use them. Everything is calibrated and i follow Mrmalty pitching rate calculator.

I have been wondering if i am overpitching even though i know this is rare in homebrewing because most of the time they show active signs at 6 hrs. 

Yeast and Fermentation / O'dells House yeast & Craft beer for the homebrewer
« on: September 08, 2014, 12:54:14 AM »
Does anyone know if O'dells brewery uses a German Ale yeast for their house yeast.  Just curious i know they are pretty tight lipped about there beers understandably, but yet have reportedly given one of the recipes in the new book, "Craft Beer for the Homebrewer" and the yeast is WLP 007 

Beer Recipes / Oatmeal stout feedback

Trying to throw an oatmeal stout together. Never brewed one and did a bit of reading and bastardized jamils Zs i think.
Any suggestions. its a 3 gal batch. Think of putting it on nitro. Also considered using pearl as the base malt instead of MO.

Does anyone know of a program besides the ones on the BJCP page that one can use to organize a homebrew comp that may be Mac compatible?

All Grain Brewing / Low PH and Dull flavor with Brown?
« on: July 26, 2014, 11:09:15 PM »
Do ya think a low mash PH of 5.2 to 5.3 will result in more of a "dull" characteristic in the finished beer? An American Brown ale

Yeast and Fermentation / Fusel Alcohol and Re pitching?
« on: July 10, 2014, 01:59:17 PM »
Well havent used WLP 007 in a while and forgot it is a monster and i let it get to hot in the mid 70's and it through off to many fusel alcohol. it is an IPA at 7% ABV and i was wanting to redue the beer this weekend and pitch using the slurry. Being that i let it get hot is the yeast somewhat predisposed to "off Flavors" or can i pitch with slurry safely and keep it low 66F.

Yeast and Fermentation / Can I predict finial beer PH?

This is a complicated ? And I know there are many variables in this ? But how and do you predict the finial beer PH?   

Ingredients / Frustrating Low finial beer PH
« on: May 17, 2014, 12:00:19 PM »
I cont to have frustrating results with finial beer PH. Is there any reason that this should have dropped by so much?
95% optic malt
5 % C120
No sparge
OG 1.042
FG 1.010
Edinburgh Ale WLP028
Mash 149F
Room temp PH with calibrated meter 2 points.
Post boil PH was 5.6  Finial PH was 4 at room temp

Water was Ca 100ppm, Mg 8, NA 14, Sulfate 149, Chloride 40, Bicarb 114, Alkalinity 94, RA 18, Hardness 284

I am was intentionally trying  make my finial beer PH around 4.5. I assume i need to brew the exact same beer with the exact same ingredients to nail it down. I even pushed the water chemistry higher than normal. I have never used this yeast though. Any thoughts would help

All Grain Brewing / Am i thinking right, mash PH?
« on: April 27, 2014, 07:09:20 PM »
I have been measuring my mash, post boil and finished beer PH for over a year now. I use a calibrated Milwaukee 101 at room temp of 77 F. I also calibrate it with a 2 point solution 7.01 and 4.01 prior to every batch. I use Brunwater to help with my calculations of both PH and ions ( Thank you martin).  So ? is am i making my PH to low? From what i understand the mash PH should be between 5.2 and 5.5 for "optimal" conversion and to be able to have control of my finial beer PH. I know there is a PH difference related to temp with about a .3 reading higher at cooled temps than mash temps. So if i measure my cooled mash temp and it reads 5.3 is it really 5.0? Furthermore if i measure my post boil PH at room temp and it is 5.2 is it really 4.9? 

I am wondering if i should shoot for a mash PH measurement of 5.6 at room temp so that my PH at mash temp is 5.3. I feel like i am spitting hairs but just wondering if my PH is to low. my finial beer PH are mostly in the 4.2 sometimes they are low like 4 at room temp. I do notice or assume that most homebrew examples i taste seem to be harsh on the bitterness where as mine are "dull"? or smooth. I tend to prefer the smoothness but others might say it's not hoppy enough.

Ingredients / Sasion Water Profile?
« on: April 24, 2014, 11:25:21 PM »
Little info out there on Sasion water suggestions that i can find. Wondering what everyone thought. Thinking
ca 70, mg 14, Na 19, Sulfate 72, Cl 20, Bicarb 220, RA 124 a little high maybe this will cause to much "harshness"?, Alkalinity 182.

Pilsner 82%
Acidulated 5.9
Aromatic 5.9
oats 5.9
SRM around 5 SRM

PH at 5.4 room temp

General Homebrew Discussion / National Homebrew Day? legal?
« on: April 11, 2014, 02:10:30 AM »
So our club is organizing an event with a local brewery and are going to be brewing for this National homebrew day.  Question is ya think it would be OK to give away some of our homebrew to the spectators?  I am from the state of idaho.  Our laws say nothing of giving away beer. I suppose that we just need to make sure no one is under age who is partaking. We are doing it in a court yard at the brewery and no need for rule on drinking in public.

Beer Recipes / Smores Porter and type of Molasses?
« on: March 26, 2014, 09:21:08 PM »
Gonna attempt a Smores porter for a local beer fest in June in idaho Falls.

Yeast and Fermentation / lager on yeast cake duration ?
« on: March 17, 2014, 07:53:56 PM »
So do ya think there is anything wrong with leaving a lager/maibock on the yeast cake for 2 to 3 weeks at room temp/64F?  Want to use my fermentation/lagering freezer to brew another batch then lager the maibock.
