The cost of each hectare of vineyard lost to blazes is estimated at R240, 000.
A fire raged for several days in the Simonsberg area last week.
At least 3,000 hectares of vegetation, including vineyards, were ravaged.
Wine industry body VinPro says the R 240,000 figure includes loss of income and additional labour to uproot vines which have been scorched.
The re-establishment of vines is also included in the cost estimate.
