Cidering for dummies:
Fresh pressed cider - no preservatives - may be flash pasteurized or not
1 campden tablet per gallon, crushed and added to cider
After 24 hours add cultured yeast of you choice or not
add fermentable adjunct of your choice to raise SG or not
Campden will kill bacteria but only stunt the wild yeast. If you choose to not use a cultured yeast the wild yeast will take over and do the job. I use this procedure exclusively and have made BOS cider this way. I use Maple syrup, Brown sugar, or honey as adjuncts. The Maple syrup needs 2 years to meld properly, Brown sugar is ready in 9 month and Honey (2#/gallon) take about a year. You can make it as easy of complex as you like. I have even used cinnamon sticks for an added dimension (BOS 2008 Amber Waves of Grain, Western New York Hombrew competition Meads and Ciders).
