Well I tasted my first batch a couple weeks ago and it was good. Waiting a couple more weeks, last night I took some over my friends house, and they tasted like carbonated water. There was a little flavor, but there was not much after taste. I did a Brewers Best Red Ale kit, and followed the instructions. Filled to the 5 gallon mark. How could it be watered down? Is it maybe infection that made it taste like this? Help me to explain.
