dry hopping at reduced temperatures?

[switzead]

i put my IPA in the primary on 10/25 at 66 degF, then to the secondary on 11/7 at 66 degF. I had to leave town for 5 weeks and i am just now getting to the dry hop step 12/13. At the same time I have 2 gallons of wine in the same cooler as the IPA that I need to reduce the temperature. Would it be ok to reduce the temperature of the IPA to 45 degrees during the dry hop step?

Yes you can dry hop at lower temps, However you will need to extend the time the hops are on the beer. Warmer temps = faster extraction, Colder temps = slow extraction. How long? Good question. IMO: I would say double the time and you should be fine!
