Hard ciders were popular in the early American colonies because they were cheap and easy to make. You could easily raise the alcohol content even more in the winter by letting it freeze and separating the higher alcohol content liquid from the ice, creating Applejack. The downside of this process is it leaves byproducts like methanol and fusel oils removed by heat distillation. This results in enormous hangovers for those who overindulge; think of the worst hangover you ever had and multiply by three. Colonists coined a phrase for this condition, the apple palsy.
