I'm onto my second keg now and have struck some trouble. The beer (a dark mild) was carbonated at 18 psi for about 1-2 weeks @ 6C. On connection to the beer taps the beer poured with nothing but froth and finally beer! Its a pain. In the beer line tiny bubbles form at the highest point of the coil, see the photo:
Any ideas what could be causing this?? The first brew poured fine and was mildly carbonated (was a different keg though).
Looking forward to any ideas.
