Forgot all about this post.
I tried caramelising a couple blood oranges in the oven just to taste before brewing, & it tasted like regular oranges. I didn't bother going through with it.
Instead I did a split batch of a red ipa, half as standard & the other half I added pomegranate juice. It was nice, it added a syrupy sweet-tartness, just as you'd expect pomegranate would. It also added a slight pink hue to the red.
Would definitely do it again, but again not a whole batch.
