So, I have recently purchased a Counter-Flow chiller and the Blichman HopRocket and had a few questions...
For the past several years, I used an immersion chiller and was able to time my hop additions pretty accurately since the time to < 160° was pretty quick using the immersion chiller.
Since I am using the counter-flow chiller, I have noticed that I need to either use whole hops, or put my pellets in a nylon bag to keep the sediment away from the counter-flow chiller. Additionally, I cannot drain my kettle too quickly, as the resulting wort only cools to about 90°F - to compensate for this, I drain the kettle more slowly.
Now my question...
If I use a nylon hop bag for a 5 minute hop addition (for example), can I simply PULL the hop bag out at flameout and the hop characteristic will stay at the 5 minute level even though it might take me 15 minutes to drain and cool all of my wort, or will that 5 minute hop addition turn into a 20 minute addition for the majority of the wort since most of my wort will remain at near-boiling temperatures waiting to be passed through the chiller?
I guess my question, more simply put, is this: Does near boiling (210°) wort change the characteristic of the hop bitterness, flavoring, and aroma of the WORT over time if the actual hops are not being steeped in it?
