Description
A vinegar produced from cryoconcentrated apple cider through alcoholic then acetic fermentation.
Technical
Ice cider vinegar begins with cryoconcentrated apple juice (achieved through natural freeze concentration), which undergoes primary fermentation by Saccharomyces cerevisiae followed by secondary acetic acid fermentation by Acetobacter species. The process preserves volatile aromatic compounds while developing complex acidity.
Culinary Significance
Valued for its intense apple flavor and balanced sweetness, used as both a condiment and flavor enhancer in dressings and reductions.
Science
