I've been planning to experiment with orange peels for a while now, but I don't know when to add them, when should I throw them in?
Last 15 minutes with the aroma hops? At flame-out? After primary? I have no idea really.
I read somewhere that citric acid and other compounds in oranges can be harmful for the yeast or inhibit their activity. Should I use fresh peels or dried ones, what are the chemical nuances to orange use in homebrew?
Thanks in advance for any advice or pointer, links and articles are very welcome!
