Making Hard Cider at Home

Hard cider is one of the easiest fermented drinks to make at home, which makes it a favorite first project for people curious about fermentation. At its simplest, cider is just apple juice fermented with yeast until the sugars turn to alcohol. You can make a very good batch with minimal equipment, and the process teaches the same fundamentals of sanitation and fermentation that apply to beer.
The most important ingredient is the juice. Use pure pressed apple juice or cider with no added preservatives, because preservatives like potassium sorbate and sodium benzoate are designed to stop fermentation and will prevent your yeast from working. Fresh-pressed juice from a mill or cider house gives the most complex flavor, but pasteurized juice from the store works well too, as long as it lists only apples and perhaps ascorbic acid.
Yeast choice shapes the final character. A dedicated cider or wine yeast produces a clean, crisp result and ferments the sugars thoroughly, giving a drier cider. Some brewers use ale yeast for a fruitier, rounder profile. You simply pour the juice into a sanitized fermenter, pitch the yeast, fit an airlock, and let it ferment at a cool room temperature. Fermentation usually starts within a day or two and can run for a couple of weeks.
Because apple juice is naturally low in some nutrients that yeast need, adding a small amount of yeast nutrient helps fermentation finish cleanly and reduces the risk of off-flavors. Otherwise, cider needs little intervention. Keep the fermenter out of direct light at a stable temperature, and use a hydrometer to track progress just as you would with beer, watching for the gravity to stabilize at the end.
Cider ferments quite dry by default, since the yeast consumes nearly all the sugar. If you prefer some sweetness, you have a few options. You can add a non-fermentable sweetener after fermentation, or stabilize the cider to stop the yeast and then back-sweeten with juice or sugar. Simply adding sugar to an active or bottle-conditioning cider without stabilizing risks over-carbonation, so plan your sweetening approach deliberately.
Once fermentation is finished you can package the cider still or carbonated. For a sparkling cider, bottle with a measured amount of priming sugar much as you would for beer, using bottles rated for pressure. Cider often benefits from a few weeks or months of aging, which mellows sharp edges and improves the flavor. With clean technique and good juice, homemade hard cider is remarkably rewarding for how little effort it takes.
