Does anyone have any experience with post fermentation additions to alter flavors? I.E. Cofee, Sugar, Hop teas, Fruit etc...... Let me know what you've tried and what works and doesn't. I havn't had any real flavor problems. All of my beers have been pretty good, but I want to be able to get exactly what was in my mind when I wrote the recipe. I've been wanting to start fine tuning my finished product with a little more precision and less chance. Any help or war stories would be greatly appreciated.
