Dry cider is made by fermenting fruit juice (apple juice, in the majority of cases). Dry cider has less than 0.5% of residual sugar and is considered more acidic as compared to other cider forms. The yeast tends to consume the natural sugar of cider and which makes it a less-sweet yet highly alcoholic. Generally, dry cider is aged in oak barrels which improves the mineral quality.
An off-dry cider has slightly more body than its dry counterpart and typically contains 1-2% residual sugar. These ciders tend to be smoother and have a richer flavor.
Semi-dry ciders contain above 2% residual sugar, while semi-sweet ciders can carry as much as 4%. These two cider types are similar in taste and have heartier bodies and more pronounced apple flavors.
