Continuing the discussion from The Plinian Legacy extract - 1 gallon kit:
I can imagine your frustration. A one gallon brew that has been dry hopped may be the most difficult especially if a jug is the primary.
We don’t know your fermentation set up or regime so these are some suggestions that may help.
A long primary will compact that yeast/trub layer as much as is possible so it interferes with siphoning the least.
A piece of fine mesh grain bag over the tip of the siphon may keep hop particles out of the siphon. This will also slow the siphon if the height drop from your primary to the bottling bucket is minimal. Longer height drops will increase the suction created in the siphon.
Use a bottling bucket instead of siphoning directly to the bottles. Siphoning directly to the bottles can work if you have someone holding the siphon to keep it out of the dry hop debris.
Cold crashing the primary for a few days will help drop hop particles out of suspension.
Adding gelatin at the end of the dry hop time may take the remaining particles out of suspension. I have never used gelation so someone else will need to comment on this.
The dry hops can be bagged if your primary is a small big mouth bubbler or bucket. Cold crashing after the bag is removed will help drop particles from the yeast/trub layer that were disturbed.
Hopefully we can help find a solution to get more beer bottled with no frustration.
