I just bottled up my house IPA, 3 oz of Amarillo dry hopped for 7 days, cold crashed at 42 for 3 days. Opened the vessel to rack and was greeted with an amazing aroma of hops, same as prior to cold crashing, no degradation noted at all.
I've never noticed a loss of hop aroma with any beer I've crashed.
