Hi Dan:

I hate to disagree with you but here in the great white north (Ontario,
Canada) I get 42 on most of my honeys(Acacia, Basswood, Wildflower,
Thyme) -checked with my refractometer and verified with my hydrometer. I
suspect that the varience has something to do with the diference in local
honey composition.

46 - 42 = 4 points

4 / 46 * 100 = 8.7 % water. I deeply doubt that any sugar with that water
content will still be liquid. Malted barley is , what, typically 4% water?
Carapils even more.

Weigh out a pound of cane sugar and add about three tablespoons of water. I
am not sure it will be sticky, much less flow. I doubt that honey has
magical properties that allow it to be a liquid with very little water.

I have a hydrometer that reads in .0005 graduations and a scale that is
graduated in hundredths of a pound. Being used commercially, the scale is
inspected twice a year by the County.

I weighed the empty container, weighed it with honey and weighed it with the
added water. This gave me the weight of the honey and the weight of the
solution. The honey was thoroughly dissolved into the solution and cooled
to about 60 F. A hydrometer reading was taken.

I took the weight of the solution and divided it by 8.345 pounds per gallon
and then divided it by the gravity of the solution to get the volume of the
solution. Multiplying this volume by the "points"of the gravity gave me the
points in solution. Dividing the points by the weight of the honey used
gave me the points per pound per gallon.

Cane sugar is almost pure sucrose. (99.9%) Honey is not. For the
sugar solution to get rid of that last little bit of water the sugars
need to form crystals. Now, for that to happen the sugar molecules
have to form nice neat structures. Pure sucrose does that easily it
is like making a brick wall. I think the highest concentration of
sucrose you can get in solution is something around 73%. After that
the sucrose in solution is just way to crowded and crystals will form.

Now, if you add some other sugars into the solution suddenly you have
a much different compliment of "bricks". Really it is analogous to
building a wall out of bricks compared to building one out of river
rocks, and you do not get to use mortar.

When you consider the water content of fairly pure sugars like corn
sugar which is dry and still has about 9-10% water in it, or even malt
extract which is fairly pure maltose, you will see solids form at much
mower concentrations than with somthing as complex as honey.

Now, with that being said, most honey you will find will get you
nowhere near 42 ppg. Generally it is around 17% water, but I do
believe it is possible to make a sugar solution that will stay liquid
at high (~90% sugar)concentrations.

I would have to believe that any such honey would be highly unstable at room
temperatures. The honey we have in the store - about 36 ppppg - will
crystallize eventually at room temperature. When the bucket empties we
sometimes heat up the crystals to blend the reliquified honey in with the
next batch.

Crossposting is the root of all evils. Please note that there is one NG in
your list that does not mention "brewing" or "making." Thanks.

You are right, I have seen sugar crystals form in honey.
Thermodynamically though it is hard for them to do so and it does take
a while. The honey I have seen it in was sitting on my parents stove
for several years.
