I am about 3 weeks into making my first ever batch of cider, using apples from an old tree in my yard (in Colorado Springs) that I have been told is a Transparent Apple. I don't know how to confirm the variety, but the appearance is similar to photos and they are very early. I've tried to take them at their peak ripest, which only lasts a few days before they turn to mush. At that point, they make excellent sweet cider. I'm hoping the fermented product is worth drinking. I'll report back here when it's done.
For years, we've been using these for apple sauce, apple butter, apple pie, eating fresh, etc. For these purposes, they've worked out quite well, but only when they've just ripened.
