Acetic acid is generally considered one of the most undesirable compounds found in cider.

The Overview: Lactic Acid Bacteria
In other articles, I described how the apples and yeast you use are the two most important elements in defining the quality of your hard cider. However, there is another component that might be equally as important but it’s often overlooked in most cider books and discussions. My hypothesis is that this is because most … Continue reading The Overview: Lactic Acid Bacteria
Volatile Acidity Versus Vinegar
Languages often have multiple words that can mean the same thing. They also have words that can mean many different things depending on the context or situation in which they are used.

This led to using oak more often and to even start experimenting with different wood, like maple, hickory, and birch. Wood is a great adjunct for cider.

Phenolics and Cider
