Caramel wild wood is recommended to mix at 13% if you look under the description for each flavor on the fox trove Etsy site it tells you the mixing percentage. I mixed at 13% and my caramel wildwood came out perfect after a 4 week steep. It might have been great before 4 weeks but I just let it sit that long before I tried it so I knew it should be good to go and it was. It’s an all day vape for me easily. Along with godfather, love that stuff.
