This looks delicious! Great idea @ironshield :) How nice that you could turn this project into a family learning experience for the kids to enjoy!
There are lots of rose bushes on the homestead here so I look forward to using them this fall when the hips are ripe. I will have to remember your vinegar :)
My girls really enjoyed picking the buds and stuffing them into the bottle. I'm not sure how to do a follow up post to describe what it tastes like... video maybe? @ironshield
