Equipment and Software / Re: Natural Gas
« on: February 06, 2016, 03:25:08 PM »
Switched to natural gas years ago.
Way better than dealing with propane tanks.
Using natural gas on my Blichmann Top Tier currently.
Was so happy with the switch I changed my big meat smoker to natural gas also.
Beer + BBQ = heaven
This is the hose I use and recommend it highly.
Quick disconnects are great.
I use the 1/2 inch hose.

Which version of Bru'n Water are you using?

So why does Wyeast recommend dissolving in warm water before pitching in wort?
I bet most, like me, toss it directly into the boil.

General Homebrew Discussion / Re: how to "improve" "finished" beer?

The best way of improving a lager is to let it sit in the fridge for months.

+1  ales too!!
Time in the fridge is magic.
Often my big ales on racking taste drinkable but not memorable.
Several months in the fridge and they are outstanding.

General Homebrew Discussion / Re: Hop addiction
« on: November 25, 2015, 07:11:51 PM »
During the great hop shortage of 2008 I freaked out and bought about 20 pounds of hop pellets.  I have no idea why I bought so much.  They now sit at zero degrees in the freezer.  Open packages are in CO2 filled PET bottles.  I am amazed how well they have kept over the years. Use them all the time for bittering and aroma additions.  Seems to have minimal degradation.  For aroma I use leaf hops that I use up rapidly.  Have not tried storing them long term.

Bought several of the Arbor Fab hop filters couple years ago.  They are the best.  Little pain in the arse to keep clean, but well worth the investment.  I even throw whole piloncillo sugar cones into them and they dissolve without burning.  Two thumbs up on this product.

Broke down and purchased a 5 gallon bucket of powdered peracetic acid last week.
Awaiting delivery now.  Will report back once I have a used this.

Your water may be close enough to give you good results.
It is just another tool to aid us who are always in search of perfection.
"My next beer is going to be even better than this one."

My water is very hard with pH 7.2 - 7.8 depending upon season.
It requires significant phosphoric acid to get anywhere near ideal pH for conversion.

Equipment and Software / Re: Milwaukee pH meter drift issues

Milwaukee MW102 has ATC, that is why there is a "temp probe".
All samples are at room temperature.

Equipment and Software / Milwaukee pH meter drift issues
« on: November 15, 2015, 12:51:51 PM »
I have use this Milwaukee MW102 pH meter for the last three or more years.
I immerse the pH probe and temp probe into the solution, wait for the hour-glass symbol to stop blinking, take the pH reading.
I have noticed if I leave the probe in the solution, the reading will drift upward in all solutions I test.
Checked my water pH last night, initial pH 6.6, hour later 7.2
Checked my sparge pH this AM, initial pH 5.7, hour later 6.2
The electrode probe was change out early this year.
Meter is calibrated before every brew session.
Not sure what to think about this.
Is first reading correct, or is last reading correct?

Equipment and Software / Re: New Bottle Filler Northern Brewer
« on: November 13, 2015, 07:42:58 AM »
Video has been posted. It seems like a pretty solid design and breaks down well. He does mention setting the pressure to 8 psi, which is far below my normal serving pressure.

Thanks for the video post.  I was considering purchasing this product until I viewed the video.  I always cap on foam to limit air in the bottle.  As the video clearly demonstrates a substantial amount of air gets pulled back into the bottle when you remove the instrument.  A design flaw in tip fillers in my opinion.  I suppose you can pull it out of the beer, then shoot more CO2 into the bottle.  Think I will stick with my Blichmann.

Equipment and Software / Re: Any US source for peracetic acid?
« on: November 07, 2015, 09:26:08 AM »
I've not seen any, but ask "why?" - the stuff is nasty smelling.  I'd rather use iodine or even bleach.

Peracetic acid is superior to other disinfectants.
Yes, liquid peracetic acid has offensive odor - strong acetic acid smell.
Powdered peracetic acid is ideal.

Powdered peracetic acid:
Practically no odor
Strong oxidizer
Broad spectrum of antimicrobial activity – effective bactericide, fungicide, and sporicide
Rapid on-contact efficacy under a wide range of conditions
Low corrosiveness on stainless steel
Removes mineral deposits !!!  (unlike bleach or iodine)
Removes biofilm and organic deposits !!! (unlike bleach, iodine or StarSan)
Decomposes rapidly to water, acetic acid and oxygen
Environmentally friendly, (unlike bleach and iodine).
Used in food processing, beverage, medical, pharmaceutical, textile, pulp and paper
Rapidly gaining popularity as a sanitizing agent in the beer & wine industry

One US source I have found:
http://www.brewcitysolutions.com/product/san-o2-gard-peroxyacetic-acid-sanitizer/
Five gallon pail for $140.
Little pricey, but then again would probably last me a lifetime of brewing.

Equipment and Software / Any US source for peracetic acid?
« on: October 31, 2015, 08:21:56 AM »
Has anyone found a US source for small quantities of peracetic acid, about one liter size or so?
It is available to commercial breweries in 4.5 gallon size ($$).
I have found it in several non US homebrew shops easily.

If I were to use peracetic acid instead, how would I go about making such a solution and where would I source the acid from?

From my post two days ago on peracetic acid (PAA):

Max limit suggested is 500ppm without rinse.
In limited data it seems breweries and wineries use 125 - 250 ppm.
Five Star and Birko sell this in 5 gallon size ($$) which is much to large a purchase for my experimentation.
I either need a source for smaller quantity or produce PAA myself.
I have found this recipe:
H2O2 5% 125ml + white vinegar 3% 75ml = PAA 200ml

I have no idea how to convert this to ppm.
Everything seems to indicate this is a "weak solution".
I have been unable to find a US source of small quantity.

Equipment and Software / Re: Effectiveness of EvaDry 500
« on: October 25, 2015, 12:22:12 PM »
I tried chemical based dehumidifiers years ago and gave up on them for use in my freezers that house my barrel collection.  Have been using several of the Eva-Dry 1100 Petite dehumidifiers.  These are very small electric units I put in my 20 cubic feet plus freezers. I set them with timers to come on/off during the day.  I have been most pleased with their performance and durability for an inexpensive little unit.

This discussion has sparked my interest to try peracetic acid (PAA) after further researching.
Max limit suggested is 500ppm without rinse.
In limited data it seems breweries and wineries use 125 - 250 ppm.
Five Star and Birko sell this in 5 gallon size ($$) which is much to large a purchase for my experimentation.
I either need a source for smaller quantity or produce PAA myself.
I have found this recipe:
H2O2 5% 125ml + white vinegar 3% 75ml = PAA 200ml
Can I convert this into an equation to calculate PPM?
Does anyone have a better method of production?
As already noted this must be used in well ventilated area.
