My buddy and I made two batches of beer yesterday from the same mash. We did a 10gallon mash, splitting the wort into two 5-gallon batches. He was making a pale ale, and I chose to make an IPA.
Both beers boiled for 60min and cooled down at the same rate. The only 2 differences were:
1) Amount of hops used (Pale vs IPA)
2) He brewed his on a propane burner, and I did mine on the stove. His reached boiling temp almost 20min faster than mine.
The end result was that his beer is a very lovely pale (as expected), and my IPA is a darker amber.
We're wondering what would cause the color difference? Is there possible "scorching" on my IPA to give it a darker color? Are hops able to, at all, affect the overall color of the beer? Could the speed at which the beer came to a boil be playing a role in the color?
