“…• As verified in previous works [15], the time duration of the coating represents a limiting factor for this application. It means that more resistant materials, having the same characteristics of candy cotton in terms of insulating efficiency, costs and simplicity of application, should be detected and tested.…”

“…This material must meet the following requirements: nontoxic, easy to use, cheap, and completely biodegradable. In this research, the possibility to apply an innovative method, already tested in lab [15,16], in the real vine plants was investigated, allowing to detect some crucial challenges which need to be solved before to test this technology in real situations.…”

“…This technique has already tested at lab-scale with very encouraging results. A previous analysis in lab [15] showed that the organic coating was an excellent thermal insulator, able to reduce the energy consumption to maintain the temperature of an electric wire, used to simulate a vine shoots, up to 0°C and thus to prevent the late frost damages. Nonetheless, it was found that cotton candy degraded quickly in the presence of wind [15].…”

An innovative method against late frosts in vineyard has been developed at CIRIAF, University of Perugia. It consists of an organic coating made by cotton candy and straw to prevent the vine shoots freezing due to late frosts. This technique has already tested at lab-scale with very encouraging results. This paper aims to experiment the effect of the organic coating applied on young shoots of grapevine during artificially controlled frost events. A vine shoot covered by the organic coating was positioned in the climatic chamber and a thermocouple was rolled up to the vine shoot to control its temperature. Also, a vine shoot rolled up to the thermocouple and without organic coating was positioned inside the climatic chamber, used as a reference case. Results show that the temperature gap, gained with the adoption of the insulating layer was approximately in the range 0.2 – 3.2 °C, but the organic coating was not enough to maintain temperature above the ice-point able to prevent the vine shoot freezing in lab. Even thought, the experimental application of the present technique allowed to detect some crucial challenges which need to be solved before to test this technology in real situations.

Wine production is a key sector for the Italian economy, representing 13 billion euros per year. The proportion of the market raises concerns about improving the production technology at low cost, safe practices, and low environmental impacts. The recurrent life cycle assessment performed does not report on the impacts of frost protection. This study presents the potential environmental impact of a novel late frost protection technique for vineyards that is currently under development. It consists of an organic coating made of sugar and straw to prevent vine damage due to frosts in vineyards in the coldest hours of late winter and early spring. From previous research at the University of Perugia (Italy), the technique has proven to be an effective protection method for vine shoots. Currently, the yields are protected by highly energy-demanding methods. For this study, we simulated two different scenarios of frosting protection so we could point out possible hotspots for the field application of the novel method and compare it to a technique usually employed in central Italy. Under the Centrum voor Milieukunde Leiden (CML) method, the cotton candy technique is estimated at 316 kg CO2 equivalent emissions for hectare. Employing the organic sugar-coating means avoiding 69,375 kg of CO2 eq. compared to the traditional technique of oak wood-burning into the vineyard. Preliminary cost analysis demonstrated the economic viability of implementing the organic coating.
