1 wk in primary, Porter tastes like wine...

[Brian211]

So I just took a reading for my Chocolate Maple Porter and my FG was 1.013. (6.3 ABV). It tasted kinda like wine. Wasn't planning on transferring to secondary, made a 1 gallon batch before of this and just did 2 wks primary/2 wks bottle. Turned out great but didn't take any readings then. I know my beer is still young (9days). I did add extra maple syrup at the beginning of the boil to increase alcohol or to make up from what I may have not extracted from the mash. The recipe also called for maple syrup at the end of the boil for flavor. Just wondering if the wine taste is from too much maple syrup or because it is still young. I know there is a lot of debate whether to secondary or not. Any suggestions? Should I let it sit an extra wk? Hoping the wine flavor goes away.
