Ditto on putting sugar in the bottling bucket first, and I'll stir after adding the beer (belt & suspenders). I've never seen the priming sugar get syrupy.
How much sugar and water did you use? I'm in the 250 - 500 ml range of water for a 5 gallon batch, depending on the amount of sugar used.
How much water do you use? I use the priming sugar calc. on Northern Brewer. I'm never concerned with the volume of sugar, but maybe my water volume matters?
I use just enough water to dissolve the sugar. I only boil it for a minute or 2.
Same just about. I bring water to a boil, dissolve the sugar, shut it off, install lid, and then label it "not wiener water"
