Cinnamon sticks and tannins

[Blu3Ridge]

I can't find a clear answer on this. Some say add cinnamon 15-5 minutes left in the boil, great results. Others say never add cinnamon sticks to a boil because it will produce tannins thus add them to a primary/secondary only.

What has been your experience? BeerSmith when I added cinnamon said add them 5 minutes left in the boil by default, and that's what I did. Now it has me worried that the boiling wort yielded tannins into my beer.

Thanks for your input.

I am not sure what it does when you add it to the boil. You can always add it in the fermenter or even to secondary. To give a good cinnamon flavor you should try 1g stick per liter. I find it gives better flavor in secondary because it is not mixed into the slush at the bottom.
