Yes, you can use bottled fruit juices, but they can’t have preservatives. That will slow or kill off the yeast. Frozen concentrate tends not to have preservatives. You still have to look. Frozen concentrates have the advantage of letting you decide how much water to add too, so you can make a fruitier ‘must’... although it’s not a real fruit must as if you actually harvested grapes and apples and pressed them yourself, obviously. I’d much rather make a real, organic product (which is why I like to make my own maple syrup), but alas, much of the year is not harvest time.
Speaking of cheery wine, I have a carboy of black cherry wine with an airlock on it, as we speak. ;)
You are right about log cabin and most of the others. What you see on the store shelf labeled “pancake syrup” is not maple syrup. It’s just high fructose corn syrup with imitation flavorings. I believe they are not allowed to label it maple syrup unless it’s the real thing.
Just read this...
Are you finding a problem and agree re the culprit?
