I've got a sour mash running right now and it smells delicious!

Just thought I'd share.

General Homebrew Discussion / Priming Sugar Data Inconsistency
« on: March 04, 2010, 10:39:59 AM »
Ok guys, I ran into an issue I can't seem to reckon out. Hoping one of you can help.

I'm putting together a simple, consolidated info sheet on priming/bottle carbonation, and I'm running into what seems to be a significant data discrepancy.

First, I reference Palmer to find that for a 5g batch, use 3/4 cup corn sugar or 2/3 cup white sugar. From this I infer that those volumes of sugar contribute a roughly equal amount of volumes of CO2.

Second, I reference Domino Sugar's reported data that 1c sugar weighs approximately 7oz. This makes 2/3c = 4.66 oz. Back again to Palmer, I see that he parenthetically notates the 3/4c of corn sugar as being 4oz.

From this I conclude that:

1. 4.66 oz white sugar will provide the same level of carbonation as 4 oz corn sugar, making corn sugar more "carbonation potential dense" for lack of a better term.

2. This gives me an extrapolated conversion factor of .86 (e.g. if you calculate the amount of white sugar you need for your desired level of carbonation, multiplying by .86 should give you the required amount of corn sugar).

Now the rub: BrauKaiser's spreadsheet, which is based on and agrees with other popular calculators and charts, assumes that corn sugar has LESS carbonation potential than table sugar by weight, due to the additional water content in corn sugar which must be discounted. In this model, the conversion factor seems to be about 1.1 - multiply weight of cane sugar by 1.1 to get the equivalent weight of corn sugar.

So according to Palmer's model, 4.3 oz of white sugar = 4 oz corn sugar.
According to BrauKaiser's model, 4.3 oz of white sugar = 4.73 oz corn sugar.

One or more of these assumptions must be incorrect. Anyone know which one(s)?
1. 1c white sugar weighs 7 oz
2. 1c corn sugar weighs 5.32 oz
3. 3/4c corn sugar provides roughly the same amount of carbonation as 2/3c white sugar
4. 4.3 oz of white sugar provides roughly the same amount of carbonation as 4.73 oz corn sugar.

Thoughts? Ideas?

The Pub / I am bored and wish to be entertained

Tell me your party trick - Name one thing you can do that is entertaining or out of the ordinary, like inhaling a dog tag chain through your nose and pulling it out through your mouth, or opening beer bottles with a fish knife.

I'll go first. I sing surprisingly good acapella renditions of old Irish drinking songs. Plus, I can touch your nose with my tongue. Which may not seem like much of a feat unless you're 3 sheets to the wind and didn't quite process what I said until after you've made the bet.

General Homebrew Discussion / Beer Tasting - Suggestions?
« on: February 26, 2010, 10:21:36 AM »
Ok, not sure of the best place to ask this, but here goes: I have been volunteered to host a beer tasting next month. For a group of women. Any suggestions on what to serve? Do I try to go the "gateway beer" route or do you think it'd be OK to throw in a HopDevil or DFH-n?

Also, I have no clue what to expect in terms of alcohol tolerance. Not trying to be sexist, but I just have no clue how to estimate what a reasonable amount of beer would be.

Any suggestions as to what to serve, and how many rounds is reasonable?
