Rack wort to bottling bucket and gently stir to mix with dextrose. Bottle

NOTES/COMMENTS:

I used golden brown sugar, but i bet it would be better with dark brown
sugar. This recipe can also be hopped, mostly for aroma and not bitterness.
you can also experiment with the recipe, maybe replace the white sugar with
dextrose or the brown sugar with molasses, honey or pure maple syrup. It
probably used honey originally.
