It was two weeks fermenting @ 44. Transferred to secondary for 1 week @58. Then to fridge for lagering. Its been two weeks and still not clearing up, very hazy. Thought maybe contamination but took a sample and dont notice any obvious off flavor. Its the second time pitching this yeast slurry (gambrinus 2002). The first pilz i brewed with this yeast cleared very quickly in the secondary. Anybody have any suggestions or similar experiences. Don't like to use it, but polyclar?
