I have used eco-flo briar brown highlight stain and always liked the color. I liked it so much that I bought a quart of it. On one project, it had a red /pink hue that I really didn't like. I thought it was the same problem as you said you had, so I shook the bottle more and tried again on a couple scrap pieces of veg tanned leather. On some leather, it was perfect, and on one scrap piece from a side that was tanned in Mexico or Brazil, it had the same red effect that I didn't like. I've read in this forum that each tannery can use differnt chemical to treat their leather. I assume that this can effect every stain that you can use whether it's Fiebings or Eco-Flo.
