RE: confused about grape concentrate - mba

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?

 Subject:     confused about grape concentrate
 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?
