I just thought I'd post an update on my batch of this for anyone who's interested. I guess it's mostly for my own benefit since I end up copying these type of notes into my beersmith.
I have 2 bottles left of the batch I brewed 10/18/2014 and bottled 11/08/2014. I cracked one of them open tonight and my first impression was just how bright it was! It's been in the fridge for weeks now so I guess it's no surprise. I'm not picking anything interesting up in the nose. Mouthfeel is full, enjoyable. After a quarter bottle (640ml) I can detect the ginger, but I think it's because I know it's there. I don't really detect cinnamon. If you told me the style was winter warmer, I'd agree with you. After all, it is warming my belly. Of course I already knew the style.
I have kept several of these bottles on hand to sample every so often since the holidays when I went through most of them. I have detected changes all along the way. I think this beer peaked around Christmas which was almost 10 weeks after brewing and 7 weeks after bottling. I'm surprised it didn't age as well as I thought it would for a 7.4%. Not that it's bad now. It's perfectly fine, but it was noticeably better around the holidays.
I'm actually glad to know this because I was worried that I was late in brewing it mid October to be ready for the holidays. Seems I chose the perfect time. Good to know for this coming year.
I'd be interested to hear anyone else's tasting notes this long after brewing it.
EDIT to add: BTW my best friend, who is a giant craft beer snob (like me) but not a homebrewer, said this was his favorite beer of mine. That meant something to me.
