Dark Beer Bread (75%) - Underproofed?

Hello friends,

I felt like finally trying to bake a bread where most of the liquid comes from dark beer.

Something curious happened that I hope you can help me explain: The fermentation of my "beer dough" progressed quite a bit slower than comparable formulas with water only. Hypothesis: Could the yeast in the beer be competing with the wild yeasts of my (whole rye) leaven - and thus slow down fermentation? 

It's not like I didn't get any fermentation at all, just not an as vigorous one. I had to cut the bulk fermentation short since I needed to go to bed (-> pre-shape -> bench rest -> final shape -> final proof in fridge til next morning).

Now, don't get me wrong: this loaf is definitely edible, outright delicious...but as you can see from the crumb shot, there's lots of room for improvement. What do y'all think?

Warm wishes from Germany,
