Hard cider is the quintessential fall beverage, the season's best traits -- bottled. With an average alcohol by volume of 6 percent, hard cider pairs well with savory meat dishes and is equally satisfying on its own. You can turn store-bought apple cider into ready-to-drink hard cider in two months using only baking yeast, a few mix-ins and a simple three-stage fermentation process.
Prep the oxidizer solution according to package directions. Soak the first-stage jug, the funnel and the stopper airlock in the oxidizer. An overnight soak is recommended. A bathtub or large sink for the actual soaking is ideal. Scrub the inside and outside of the jug and all the implements with a bottle brush.
Immerse the jug, the funnel and the stopper airlock in the sanitizer for at least five minutes. Do not rinse. Use immediately, or store the jug and implements in a hot dishwasher until you're ready to do so.
Fill the first-stage jug halfway with cider, pouring through the funnel. Combine the room temperature apple juice concentrate, tannin, pectin enzyme and yeast nutrient with the cider. Rehydrate the baking yeast in lukewarm water. Let it sit for five minutes until the yeast blooms.
Add the bloomed yeast concoction to the half portion of cider. Shake the jug gingerly to disperse the yeast. Transfer the remaining cider to the jug. Insert the stopper airlock into the jug mouth. Move the jug to a dark space where temperature hovers at 65 to 70 F. Allow fermentation for one to three weeks.
Oxidize and sanitize the funnel, the second-stage jug and the cheesecloth. Place the cheesecloth into the funnel like a coffee filter into a brew basket. Set the funnel into the mouth of the jug. Remove the stopper airlock from the first-stage jug. Pour the cider into the second-stage jug.
Dunk the airlock stopper into the oxidizer and the sanitizer. Plug up the second-stage jug mouth with the airlock stopper. Allow the cider to “mellow” for one to three weeks. Transfer the cider back to the stage-one jug after three weeks.
Put any spices and flavorings you like into the jug using an oxidized/sanitized measuring spoon. Seal the jug and let it settle for another week or two.
