Have you noticed a difference in taste after a littlr age?
Absolutely! The type of yeast makes quite a difference as well. I was using Cider House Select yeast for most of last year. Cider tasted slightly "barfy" the first week off the rack. A month later it was better, and three months later the off flavor was gone with just delicious cider left behind. I've been told this is due to infection, but also told it wouldn't
clear up over time so I don't know what's going on there. I suspect the table sugar has wild stuff in it that's competing with the yeast and I should probably pastuerize it before adding to the cider. This might solve the problem.
I saw a youtube video earlier this year where they used S04 in their cider. I thought cider needed specific yeast but guess not. I had some S04 in the freezer and gave it a try. Wow, what a difference! The cider is nearly drinkable right off the cake. Very little detectable off-flavor. I've aged some S04 out a couple weeks and it just gets better. Last week I tried some Kviek. It's super clear. Going to try that this Friday with some friends.
Cider definitely benefits from aging. How long might depend on your process.
