I'm having a hell of a time bottling my 1 gallon batches. I've tried 2 different racking canes from Northern Brewer and I end up with what I perceive to be way too much oxygen going into my bottles. What do all of you use for racking out of such small batches? I have been fermenting in the Little Big Mouth Bubbler, which means I have a hard time starting a siphon without ending up aerating everything like crazy. It sucks making a small batch of beer and watching as fermentation does its thing perfectly, and then having the stupid siphon backfire a bunch of air into the beer as you're trying to bottle.
Here's my process when I brew one gallon batches, (actually closer to 1.25 gallons). Like you I'm also fermenting in the 1.4 gallon Little Big Mouth Bubblers. I bought a smaller siphon from my LHB shop and I siphon into a 2 1/2 gallon food-safe bucket I picked up at Lowes. I drilled a hole in it and installed a spigot. I have a two or three inch long hose coming off the spigot and a bottling wand attached to the other end of the small piece of hose. I rack to the bucket (no sugar at this point). Using a tip I picked up from @TwistedGray I use a sanitized funnel and measuring spoon to add between 1/4 and 1/2 tsp of table sugar (depending on style), to each empty bottle. I rack the beer on top of the sugar, usually getting 10 to 12 bottles per batch, and then cap the bottles.
I haven't really had an bubbling issues with the siphon as long as I keep it fully submerged. Have you tried a different siphon?
