Made my first 5 gallon batch recently. Initial ingredients were 4.5gal of apple juice and 6 tubes of concentrate. All was well and good and at 1 month it tasted like a pretty typical young cider.
Bottled about 4 days ago with 5 more tubes and 1 cup of maple syrup. In the past I've had very good luck with small batches using these proportions. The results are mellow and sweet. BUT...
Tasted one tonight and BLAM. Like biting a crabapple. So my question is, what happened? did I just use too much concentrate? Did all my bottling sugars go to alcohol in just 4 days? Is this something time will fix?
