Cider

"Cider is an alcoholic beverage made from the fermentation of apple juice. Quite popular during holidays and in more northern climates."

Cider is a new type of alcohol added by the Bottling and Booze expansion. Able to be consumed once daily without any chance to become addicted for a fair amount of recreation, a minimally detrimental high (5.12 hours with a +10 mood buff for -2% manipulation) and a small amount of nutrition (0.06), Cider is a fantastic option for colonies with a good excess of apples, especially those in temperate forests. It also sells for an okay price, making it a solid enough trade good, taking only half the time to brew and only being worth $5 less than Fruit Wine, which apples can also be used to make.

Acquisition
Cider can either be bought from Alcohol Traders or brewed from Apples at a 5:1 ratio of apples to must.

Crops per Barrel
Because the rate at which trees produce their fruit is independent of soil fertility (more testing required?), soil fertility does not play a role in how fast fruit is harvested after the tree has fully matured.

As such, 10.26 Apple Trees taking ~12.31 days in proper growing weather producing 10 apples per harvest would be enough to continuously run 1 barrel with an excess per quadram of 3.125 apples.
