The lower the temperature, the longer it takes to extract the aromatic oils. So a hop stand at 140* for 20 minutes might be similar to a hop stand at 110* for 45 minutes or a hop stand at 160* for 10 minutes.
He didn't recommend a time period for a hop stand at 110*. Damn it!
But the higher the temperature the more of the various oil fractions are volatilized and lost. Hop-backs and torpedoes aim to get around this by making it so the extracted oils have nowhere to go until they are cooled and "stuck" in solution.
