Wyeast have a great yeast strain for this. unfortunately, it is not available the whole year long: YEAST STRAIN: 3763 | Roeselare Ale Blend
It is a mix of ale strain, a sherry strain, two Brettanomyces strains, a Lactobacillus culture, and a Pediococcus.
This is exactly what you need for a Flemish Old Brown (sour red/brown).
This strain comes from Rodenbach.
Give it one year -before that, your friends will think you're trying to poison them- with some light oak chips (not even necessary and you will be astonished!)
I will look for my recipe and post it.
