Spoilage

Game guide on spoilage https://www.farthestfrontier.com/guide/gameplay/food/#q08

Spoilage is an ongoing measure of decay of stored food and other resources. All items that spoil have a base spoilage rate that can be extended through a few different mechanisms -- conversion to a new resource type, Storage Buildings, and barrels.

Upon reaching Spoilage lifespan, any resources that were unused are lost and will vanish.

For a full list of spoilage rates, please review the main Resources page for the resource in question.

Conversion Buildings

 * Smokehouse - Converts Fish and Meat into their smoked equivalents
 * Cheesemaker (Building) - Converts Milk into Cheese, vastly increasing longevity to 36 months
 * Preservist - Uses Glassware to preserve root vegetables, berries and fruit.

Storage Buildings
''NOTE: Storehouses/Warehouses and Markets do not inherently increase longevity of goods, but can use barrels to increase longevity. Stockyards do not reduce spoilage nor benefit from Barrels''
 * Root Cellar - Provides a passive increase to longevity of stored resources, significantly improved by upgrading to Brick Root Cellar
 * Granary - Provides a passive increase to longevity of stored grain and flour (not explicitly listed in the interface)

Barrels
Barrels reduce the amount of spoilage of 5% per barrel, buildings which use barrels can add to this effect by keeping up to 5 or 10 barrels in use for a net increase of 25-50% of spoilage longevity.

Barrels with 1 month left of durability are still 100% effective at Reducing spoilage of 5%

Barrels last for 86 Months Total.

Barrels with 1 month left of durability are still 100% effective at Reducing spoilage of 5%

Additional Notes
Resources stored in the Trading Post do not currently spoil as of version 0.7.5.

This is understood to be temporary behavior that will change in future releases.
