I just got a retort for Christmas wooh, but my yields are terrible most likely caused by a lot steam passing out that isn't condensed , is there a cheap way to help condense this steam to improve yields?

Depends. What are you distilling?

well, one way to improve your yields would be to apply less heat. sure it will take longer but you will lose less.

you could attach a tube to the retort and pass the steam through a glass tube immersed in ice water. It would act as another condensor and improve your yields but it kinda defeats the purpose of the retort. You would also have to build a water bucket with a hole in the side.

I'd reserve a retort for high boiling materials that demand strong heating (and will condense easily with only air cooling), but that aside, cooling the neck in some way will give you your desired effect. You could run ice water over it, but you'd need to attach some sort of something to the end of the neck to keep the water from getting in your distillate. A bead of caulk intended for bathroom work would be a good waterproof "glue" to attach such a barrier
