1. Heat sugar and water mixture to boiling.
2. Pour into bottling bucket
3. Siphon from primary to bucket. keep siphon intake from touching the yeast cake, I even leave an inch or 2 of beer on the cake to avoid sucking that stuff up.
4. Siphon "quietly", put the outlet tube on the bottom of the bottling bucket to encourage swirling and mixing with sugar, but discourage splashing and aeration
5. Start bottling...The first bottle will get a bunch of air in it from the siphon tube being empty from the primary to bottling bucket finish. I always fill that bottle up halfway, till the siphon is full again, then come back to that bottle last.
I fill my bottles up and keep a tupperware container full of starsan and caps next to me, and set a cap on each bottle as I fill, and then crimp them when I finish.
