Do corporately organized wine producers cope better with unfavorable weather conditions than private wine estates? Hedonic pricing models for South African wines

In our research we want to estimate the effect of changing weather conditions on south African wine prices for both, small wine estates and corporately organized producers and to compare these results. We assume that the latter cope better with unfavourable weather conditions than private wine estates, whereas beneficial weather will be favourable for both of them. We focus on the South African domestic wine market, as prices on export markets are additionally influenced by other factors, such as marketing strategies, certifications, mark ups of wholesalers or retailers etc.
