One thing about being first, you can be dead wrong but you're still
first!! Personally, I think this is a great experiment to try just for
kicks. It would also be interesting to gather all the hydrometers and
refractometers and see how well they are actually calibrated.

Three experts 3 different answers. Is there a reliable formula or
table for converting Brix to Specific Gravity?
Greg
I think Rick had the right answer.
Brix and Specific gravity are not a linear relationship so forget converting
back and forth
Brix is a measure of %sugar which Rick designated as "gravity units"
He adjusted the %sugar (68) by the change in volume(92/640) to get the new %
sugar (9.775) then converted to SG (1.039).

use the table found at http://pump.net/liquiddata/specgravsugar.htm

How about this for a way to estimate your final gravity. To simplify the
calculations ignore the amount of liquid in the concentrate.
Multiply the brix measurement times 4. This gives 272 or a specific gravity
of 1.272. Multiply the 272 times 2 (2 cans of juice) you get 544 or a
specific gravity of 1.544. Now dilute the juice with 5 gallons by dividing by
5 to get 109 or a specific gravity of 1.109 which sounds about right for the
starting gravity of wine.

Jonathan, Moving from American to metric and back to American units of
measurement is always fun and challenging - don't you think?
One way to think about this is to separate the input from the results.
For input, multiply strength times volume and arrive at total strength
in gravity units/something. Here is a try.
68*46*2 = 6256 "ounce gravity units" Since you will be diluting to 5
gallons, you need to spread out this stuff WITHIN 5 gallons. 1 gallon
is 128 ounces so 5 gallons is 640
Dividing the ounce gravity units by ounces (6256/640) arrives at
gravity units in Brix. The final gravity of your solution should be
about 9.775 Brix or approximately 1.039 O.G.
And you know if I missed this by a country mile, someone is a-going to
let me know!

68 brix is 1.3384 specific gravity at 60F - does that help?

Cans of Alexanders grape concentrate say they are 68 brix. I'm thinking of
making a pyment and I'm not quite sure how to calculate gravity with these
concentrates. The cans are 46 oz. You need 2 cans for a 5 gal. batch.
So...what will the OG be if 2 of these cans are diluted in 5 gallons of
water?
March is just around the corner, and so is MARCH MASHNESS
The 2003 MARCH MASHNESS will be judge in St. Cloud on March 15-16.
They are accepting entries between Feb 26th and March 12th
* $6.00 per entry
* 3 bottles (clean 12oz green or brown long neck) per entry
* Only one entry per category
Entry form, rules and labels are on their website:
http://www.cloudytownbrewers.org.
We have a volunteer to drive the entries up to St. Cloud (Thanks John!)
I will collect entries at the BJCP class Thursday Feb 20th @ Rick Oftel's
house and Thursday Feb 27th @ Midwest or they can be dropped off either
Tuesday Feb 25th 6-9 pm or Wednesday Feb 26th 6-9 pm at Harwell's Steakhouse
& Brewery in Shakopee
I will have blank entries forms and bottle labels available at drop-off.
