The Pub / Re: Busy Day

I am at about 6,000 ft. up the side of Mauna Loa in Hawaii Volcanoes Nation Park.  One of our Scouts in Troop 65 is leading his eagle project - planting 700 indigenous Hawaiian trees in a former ranch area in the park.  I have been conscripted to stay at base camp and cook lunch - chicken hekka, sausage fried rice and chili.  The planting crew was supposed to have been down for lunch a half hour ago.  Got a few free minutes, so I thought I'd check the forum via iPhone.  Pretty cool that there is 3G signal this far up in the forest.

Sugar ferments faster and cleaner when it has been inverted first.  The yeasties can concentrate on fermentation only instead of conversion and fermentation.

That's the theory.  In real life brewing I haven't found that it makes any difference.


Brewing?  Hmmm...  I hadn't thought about it that way...   ;)

How about putting one of these stainless steel scrubbies around your pickup tube?




Those make excellent column packing.

No big ting bruddah.  The amount of priming sugar used is insignificant compared to the fermentables in your wort - say a few ounces of sugar compared to numerous pounds of malt fermentables.  The sugar will ferment out in the 2ndary fermenter with minimal, if any, noticible affect.

I just prefer my method - stay home until the snow goes away.

That thing is never going to work unless they re-align the Pfetzer valve with the sommel flange.

No, that's the beauty of this model!  They've added a pre-ionization nebulizer that maintains valve alignment automatically.

It think it is more important to have consistent hydrometer readings than it is to have precise readings. After all you want repeatability. Precise readings are nice to have if you want to exchange that data with other home brewers.

I agree.  Precise (consistant) readings are good for repeatability.  Precision allows one to track changes despite inaccuracy.  However, accuracy is needed to exchange meaningful data with other homebrewers.

As a system operator I sometimes have to track process trends using precise online monitors, whose accuracy is out of calibration.

Just a thought...  how important are exact hydrometer readings?  Could you tell the difference in a beer with an original gravity reading of 1.048 that should have been 1.052?  Is an error of 0.004 gravity points significant?  Can $10 hydrometers be counted on to be accurate to 0.002 gravity points (the smallest graduation on most HB hydrometers)?

I know several brewers who brew by recipe only and never take specific gravity readings.  Their beers taste just as good, time after time, as any I've tasted where the O.G. and T.G. are known.  I kid them that their brewing is like driving a car without a speedometer.

I use the flask and scale method because I can and it's convenient.  I work with lab equipment daily.  More often I use it to calulate ethanol content.

My first thought was "wrong kind of engineer".

My second thought was "that is just made up gibberish".  I'm right?  ;D

I use a class A volumetic flask and a scale with 0.001g resolution.  That is a direct measurement of density, not a correlation to buoyancy.  In this case I sight the reading across the bottom of the concave meniscus.

I thought it was this (<-- That's a link).

Naw, that's just Homer Simpson having fun Homer-style...   :D

I was going to suggest that, but did not because lemon flavor may persist and make its way into the beer.  I don't know if it will.  I always use citric acid to invert sucrose before I ferment.

It's very easy to make your own.  You need:

4 cups cane sugar
2 cups of water
1/4 tsp citric acid (available from LHBS)

Mix the sugar and water in a pot and apply heat.  When the mixture is dissolved add the citric acid and bring to boil for around 20 - 30 minutes, stir often.  Some darkening of the solution will occur.  No worries.

Cane sugar is sucrose.  Inverting the sugar splits the sucrose molecules into glucose and fructose molecules.  These two taste sweeter than sucrose.  

Yeast produces invertase enzyme to invert sucrose to glucose and fructose before fermentation.  Bees produce invertase to invert nectars to honey.

Sounds like betting agains him is the way to go.......crap, I'lll run out of wood pellets..... >:(

He's doing better than Algore...  ;)
