Just finished my first batch of cider (only 2L, cuse thats the size of carboy I have). I did a number of things wrong, so that it tastes OK (watery but not bad) is a bit of a miracle! My girlfriend thinks the cider tastes very alchoholic, I'm not so shure. no added sugar or anything, just organic juice and yeast.
is there a way to figure out after the fact roughly what percentage this stuff is? and if so what is peoples preferred method?
