Hazlenut Beer

I did a spiced beer with a tiny bit of nutmeg, cinnamon, and allspice last year. It was okay but i added too much spice to it. I agree with the comment above though. I had one of the bottles sitting around till now (so around 7 months) opened it and it tasted horrible. I am not sure what happened exactly, but it was like the flavors that balanced the spice all died down and there was nothing left but overpowering spice (particularly cinnamon).
