The cost for a cider farm is one hundred gold coins, five wood, and one tool. For full production speed at least four orchards must be planted for twenty-five gold coins apiece. That brings the total cost for a fully functioning cider farm up to two hundred gold coins, five wood, and one tool.
Cider farms will only produce cider on islands with the requisite fertility which only appears on occidental islands. Cider seeds can be purchased from Lord Richard Northburgh and planted on any occidental island that has a customizable resource.
