I made a spruce beer last year. I THOUGHT it would make a good IPA and I THOUGHT it would pair nicely with the hops ,I also THOUGHT that the pine flavor would be something I wanted in a beer. Well turns out I THOUGHT WRONG! !! It was just plain nasty,tasted like pine-sol cleaner. Everybody that tried it said the same......Good luck,and I hope you have better results!
I did a maibock a couple years ago, and the fir tips worked beautifully! Citrus and "fruity" flavors. The only problem was that judges who expected the fir tips to taste kinda like Pine-Sol kept saying they didn't taste them, but that maybe I fermented too warm.
All that to say, maybe try a maltier style?
