Grapes can be be used without processing as a pleasure food fullfiling the quadenary need Pleasure food.
The natural patches seem to be quite loose but still more densly packed then Apples a typical patch ban be fully exploited by a single gathering camp.
The gahter rate for natural patches lies between XX and XX
The Gather rate for fields lies between 0.1 and 0.2 the gather rates seem to match the gather rates for other crops found in the chart of Field
The fields however are exploited more efficently by the Gathering camp and the Farm this allows gathering camps and farms to exploit double the amount of fields. instead of working 20 flieds of wheat a gathering camp that exploits grapes can exploit 40 fields of grapes while at the same efficenty as the gathering camp exploiting the 20 wheat fields.
Since grapes van be grown in the Mediterranean and Continental biome there is a chance that grapes can be placed in fertility 2 or 3 this impacts the production value of the field annex it it thus adviesed to place the field annex in the highest possible fertility if a big output is desired.
Here is a chart with biomes grapes can be found and grown in.
