Grand winery makes farm produce 80%instead of 20% olive oil, ontop of the 100%food
Olive oil can be used to train units for same value of recourses, so its gold and wood also
+
45% increased farm rate upgrades
*
125% Aqueducts (improves it says, instead of increased)
*
1.3 Final landmark that spam unit for free (better then olive oil siege production)
+
2nd landmark that spams unit for free (better then the 250over10sec heal flasks)
Extra ezz = the 10wood cost only of ''spearman'', they also run 15%faster
To ''waist'' food on military, to fuel the olive oil eco.
I myself use Olive oil only to produce Crossbow Elephants. (400food+600gold, now cost 1000 olive oil(so a olive oil into 60%gold converter)
those 26 vills around the grand winery have best production ingame (180%*1.45*1.25*1.3=424%)
Since spearman cost 10wood instead of 20wood, that's a 848%wood army spam effectivniss
