I live in the North East part of the United States and have been an avid bushcraft enthusiast, offgrider and forager my whole life. My passions lie in doing everything I can from scratch to the best of my ability, so I'm curious to that end if anyone has suggestions for oil rich plants that can be found in my neck of the woods, along with the times of year I would be searching for an collecting them. Not only looking for cooking oils per se, but oils that might be useful topically in cosmetics and lotions, even if only harvestable in small amounts, or oils that generally are inedible but might be useful for sealing wood, as a waxy waterproofing agent, or as a fuel source.

I prefer invasive plants personally as I prioritize their harvest and removal from my local ecosystem, but I'm open to any suggestions.

My current ideas mostly are:

Black walnut
Algae/floating plants(Such as spirulina OR duckweed)
Lilac Seeds

Mustard seeds(Bittercress, wintercress, garlic mustard, dames rocket, ect)

Basswood/lindenwood nut oil*

Autumn Olive Seed*

Wild Grapeseed.

Redbud, honey locust and other local legumes

*I'm unsure of the oil content of these fruits as there are no major resources for it's chemical constitution that I've found. Any would be greatly appreciated

Any other suggestions for plants and techniques for oil extractions would be greatly appreciated :)

I've been getting into making wine the past couple of years and I like to keep everything as low tech as possible, salvaging what I can from my local environment and using local ingredients. I really don't like having to order things in online as well, so I was curious if I could use kombucha as a starter for converting a wine into vinegar, or simply use a sugary mash to make vinegar. I'm aware that SCOBY's have acetobacters that would normally form in the mother of vinegar, but I'm not sure if there would be any hiccups along the way or if it would simply be easier to capture wild bacteria with open air fermentation. Thoughts?
