I recently got a bag of t85 flour and I had some whole rye from the same mill as as well. While not as open as I guess I would of loved, this bread is great. its dark and earthy and to be honest a nice change from most of what I have baked lately.
700g t85 85%
50g whole rye 6%
150g 100% levain (75g flour 9%) (75g water 9%)
667g water 81%
16g salt 2%
