Porter Split Batch Experiment

Big Brew day I contributed 3 gallons of porter with the intent to split into 3 secondary fermenters to make 3 distinct beers.

I made coconut extract about 2 weeks ahead using vodka.
The second beer was Chili Pasile added directly in secondary. I sterilized them in a 200F oven for 30 minutes.
After 1 week in the primary, they go into the secondary. Used 2/3 of a cup of coconut extract into the one, and 3 chilies into the other. The last gallon was plain.
Putting them into the bottles I noticed a white substance (probably coconut fat and solids) floating on the surface so i pulled into another vessel to pull that off. Also noticed a red oil on the chili beer surface, so pulled that off as well as best as I can.
