Equipment and Software / CFWC upgrade in the works.
« on: December 05, 2011, 07:09:25 AM »
I am using 3/8" copper tubing, but was thinking about going to 3/4". I would obviosly need to use a bigger diameter hose and reduce to be able to hook up to my hose bib. How much of a difference whould I see? Can I chill using less water; would it go faster?

Yes? No? Doing a pils.

Equipment and Software / Whirlpooling question
« on: November 30, 2011, 08:18:36 AM »
Right now I use a Blichman Hopblocker in the BK. After my boil I let the hot break settle for about 30 minutes then the wort is pumped thru a cfc on its way to the fermenter. Problem is I get all the cold break in my fermenter. I was thinking about recirculating the wort by pumping thru the cfc back into the kettle to create a whirlpool; keep recirculating thru the cfc till I am at (or close to) pitching temp. Then do my transfer. What do tou think?

Ingredients / Oat Hulls VS Rice Hulls

Doing a Guiness clone that calls for oat hulls. ok to use rice hulls instead? any difference?

Equipment and Software / Reusing carboy
« on: November 29, 2011, 07:25:50 AM »
I am doing another brew today and was planning on repitching from a batch that's ready for kegging. I usually pour the yeast cake into a clean carboy and transfer the chilled wort, or vise-versa. Can I just transfer onto the cake reusing the same fermenter? Seems there is'nt anything in there that will harm the new batch. What do you think?

Ingredients / Using Rainwater for brewing?
« on: August 26, 2011, 06:53:19 AM »
I have these 2 55gallon rainbarrels and was just wondering. We are expected to get lots of rain this weekend (Irene) so i think the gutters will get flushed pretty well. Would there be any concern using for mash/sparge water?

Ingredients / Got my water report-- Now what?
« on: August 18, 2011, 12:12:46 PM »
All you water chemists sharpen yer pencils:
pH: 7.7
Total Hardness (CaCO3):128
NO3-N: 0.1
Total Alkalinity, CaCO3: 113
That's straight from my well, and thru a carbon filter (to remove the Iron which is pretty high). We have a "softener"  (i guess that's what it is- bags of salt etc.) but the water tested came straight from the well/carbon filter. Do you think the water softener water would be better, should I get that tested, or stick to using bottled/spring water? I have noticed sometimes the filtered well water has a slight rotten egg smell. I live in Davidsonville MD. Is treating it an option, or beyond hope for brewing with? what should I do?????

First question:
I have a RIMS and I am trying to figure out what the correct water to grist ratio should be. Lets say I am using 10lbs. of grain. If the recipe calls for 1qt. per lb., I figure 10 qts. plus an additional 6 quarts to make up the dead space under the false bottom and RIMS plumbing. So, my water to grist ratio would be 1.6 quarts PPPG. Thus, 20 lbs. grain would be (20x1)+6=26qts or1.3qts. PPPG. Am I figuring this correctly? And if so do I use the corrected ratio (in this case 1.6 or 1.3 respectivly) for determining my strike temp?

Second question:
I am using a grain absorption rate of .13 gallon per lb. of grain. Is this a static amount? And since I am brewing 5-10 gallon batches, do the above rates change enough to require alteration?

Thank you for your help. Pi

Yeast and Fermentation / Mash first; starter second?
« on: August 17, 2011, 03:07:21 PM »
I was thinking instead of making a starter using DME, what if I mashed an extra gallon, and used it to make the starter. Maybe chill the (Pale Ale 1.058) wort until yeast is ready to pitch, than bring the wort up to room temp.? Is infection a concern?

Equipment and Software / Hannah PH testor all dried up?
« on: August 17, 2011, 02:51:25 PM »
I got this from a friend. Still in the box but was wondering if the bulb is toast. If I buy the calibration solution(s) do you think it is still ok?

Classifieds / Wanted: Wet Hops

Interested in buying some wet hops. If you got in on the recent sale by-the-pound, I can take a few ounces off your hands.

General Homebrew Discussion / Cleaning Glass vessles?

I have noticed my Erlingmeyer flasks are starting to get kind of hazy. Is there something i can use on the to get them to sparkel again?

Yeast and Fermentation / Wyeast 2206 Bavarian Lager Seems sluggish
« on: August 17, 2011, 06:40:30 AM »
 Never used this strain but things appear pretty quiet in the carboy. I pitched at 55f. I did not wait for the pack to swell. It's been about 30 hours now, and I'm getting about 2 bubbles a minute. Do you think I underpitched? I also used Fermcap btw. Should I repitch or RDWHAHB?

Equipment and Software / RIMS getting lots of grain in the sparge
« on: August 15, 2011, 09:07:33 AM »
I did an Oktoberfest yesterday and noticed a crapload of grain particulates in my runoff. After collecting 7 gal. of wort, i decanted and ran thru a muslin bag. there was about 1/2 to 3/4 cup of grains in the bottom of the kettle. Would this be enough to throw off-flavors? I have been running my RIMS at full on; do you think slowing the reculation down might hepl?

Yeast and Fermentation / Low attenuation please help
« on: August 11, 2011, 01:50:58 PM »
I cant seem to figure it out. Tried using spring water, bottled water; extract brewing; well aireated/oxygenated wort; adherence to recomended pitching rates and fermentation temps, but still getting roughly 50%ADF when i should be getting 75. I did two seperate Identical batches using the Pilsner Urquell clone recipe discussed in Zymurgy (July/August 2011) Double decoction vs triple, OG 11.6P. After racking to secondary i'm getting like 5.9P. In past experience, after a 4 week lager, I'm lucky if I get anything lower than 5.5P. What gives?
