Taste Test... like wine?

So I took a sample yesterday of my beer I brewed 3 weeks ago... I took about 6 oz to my brother to try and he said he thought it tasted a bit like wine... obviously the beer is not y et carbed and only 3 weeks old so I wonder if this "winey" taste is due to it being young or what. He said it was actually pretty good just had a slight taste to it.

It was an IRISH Carbomb stout recipe. And this was without any of the whisky/vanilla added to it.

I am off tomorrow so I plan on bottling tomorrow and letting sit for 3 weeks.

I would guess he was smelling isoamyl alcohol, it's a fusel alcohol that's common in beer. It's also common in wine and much easier to detect because it's usually at much higher levels than you'd find in beer. Just a guess though.

it was because it was not carbed and way too young.

That's what I had told him about it being too young/not carbed. Just was hoping it wasn't an infection etc. Going to bottle tomorrow. And hope to brew another.

Let him try one when it is done. Do not let him know it is the same beer though.
