| Resource Overview | History |
Wine is one of the 31 rare resources. It appears as a small vineyard with green vines and several stakes (so-called 'trellis').
Like all rare resources on land, Wine can be gathered by sending a Merchant from the Market to the resource location. Wine provides the following benefits:
- +10
Food gather rate - +10 Knowledge gather rate
- Base cost of unit upgrades reduced by 20%
- Ramping unit upgrade costs are not affected, so there is no additional benefit if upgrading existing units to a more expensive unit compared to researching the upgrade without any existing units.
- The cost reduction affects all unit upgrades at the Barracks, Stable, Siege Factory, Dock, Airbase and Missile Silo, but it has no effect on the upgrade cost for Generals and Spies at the Forts.
- The cost reduction is cumulative with bonuses granted from resources like Salt, Horses, or Sulphur.
The gather rate of rare resources can be increased in various ways, as described in the main article. Note that 
Knowledge is not gathered before the 
Classical Age, but the Greeks may gather Knowledge from the beginning, making an early exploitation of Wine more useful.
