Brewed 3 AG beers in 2 days with no problems until chilling. I have a Blichmann top tier setup and am using a Shirron plate chiller. The first batch, a honey wheat, would only get to 80 deg. I assumed this was what my water temp from the tap was, and after checking with a different thermometer found it to be true. I then put my carboy in an ice bath and had to pitch at 72 degrees. The next batch was a pumpkin ale. Again all is well until chilling this time I put approx. 2 ft of hose in an ice bath and choked the flow out of my brew pot way down and still could not get sub 80 deg. I used a conical this time and again had to do an ice bath and pitched at 75. Then today with a scotch ale same problem. This time I used an emersion chiller to chill down to approx 85 deg. Then I put my entire plate chiller in an ice bath for about an hour to get it good and cold. I restricted flow and could only get it to chill to 76. I went ahead and pitched anyway. My questions are this 1) what can I do differently to achieve a 68 deg pitching temp. 2) Is there a better way to change my setup. 3) Should I go with blichmanns plate chiller. 4) will my brews be ok since I pitched above 70? FWIW these are all ales and all 5 gallon batches. Thanks for the help in advance.
