Besides the smell of alcohol, is there any peculiar smell? Is it the refreshing alcohol smell, or is it spicy? If it has a fragrant aroma, it must have been fermented, like making fruit wine or something. If you are worried, don't eat it. This is the safest. If you're curious, you can try it, it should smell like alcohol. If it tastes spicy, don't eat it. It's definitely not good.
