This year too, late frosts have actually ravaged red wine production in whole locations and in specific in some areas beyond the Alps. The images of the so-called “fires” produced by paraffin “anti-freeze candle lights” or genuine hay “bonfires” utilized to heat up the air and to develop genuine smoke screens efficient in protecting the shoots from freezing have actually gotten into social networks. The exact same chooses overhead sprinkler watering that some wine makers (specifically in champagne) usage by making use of the double capability that water has, as to start with it launches heat when freezing, keeping the temperature level of the environment greater, and second of all location integrates the plants and their shoots within a layer of ice that is continually restored, keeping the temperature level around 0. It is extremely beneficial (supplied there is very little wind) as damage to the shoots must manifest itself substantially from -4 ° C down. The old anti-frost watering systems are slowly being changed by more sustainable and efficient ones with micro-sprinkler innovation called “Flippers”, created to enhance making use of water by striking just the vines, with cost savings of more than 45%. Amongst the most contemporary innovations there are, then, the big fans (the towers can reach a height of over 11m) are mobile or set wind turbines (extensively utilized in Bordeaux), begun by a thermostat which is activated when the efficiency criteria are reached. set temperature levels. The concept is easy: geared up with a big turning fan and placed a minimum of 6/8m above the vines, the maker moves the air, returning the hot air present at height towards the level of the rows, expelling the cold air that collect at the bottom. Each fan has the ability to “secure” a location of 4/6 hectares of vineyard. Undoubtedly, even in this case, the temperature level needs to not fall listed below -4 ° C. This service is likewise utilized in mix with the lighting of “bonfires” at the edges of the vineyards to integrate the result of smoke with the thermal convention. Just recently we have actually likewise checked out steam atomizers utilized as “anti-freeze”.
Yet, there is an image that struck me more than the others and it was that of the vineyards of an essential Piedmontese truth in which you might see rows and rows of what seem luminescent LEDs running along all the rows. Soon afterwards I handled to call the business that holds the patent in concern: Frolight.

Here’s what they discussed to me about their fantastic development:
— When and how was your organization born?
Frolight was developed in 2019 and established throughout 2020 and 2021. The real marketing of the system started in 2022. In specific:
2019– Research study and advancement of frost defense based upon infrared innovation– Building of the very first model 2020– Favorable outcomes of the model in small vineyards– Advancement of the control system and in-line platform– Advancement of the business item– Worldwide patent 2021– Development of Frolight BV– Favorable outcomes on 4 vineyards with the business item– Authorities statement of the Frolight System by means of media2022– 82 systems offered– Active in 7 nations in Europe– Growth outside Europe with Chile– Test results handed down strawberries– Recognition of crucial research study institutes2023– Currently more than 400 systems offered– Active in more than 10 nations in Europe– Extension of the circulation network– Growth outside Europe with Chile and the United States
— How does your frost defense system work?
We utilize IR light to heat up the vine shoots. This is more effective and efficient than convection heating. It is electro-magnetic radiation, made up of electro-magnetic field waves to move energy. Protection is 360 °, with more effective energy transfer. Many systems readily available on the marketplace are based upon convection heating to secure crops, with heat transfer through motion of liquids and gases (e.g. air) in which the heated air just increases upwards and the energy shift it mishandles.
— Is one system environmentally and financially more sustainable than others?
Frolight operates on electrical energy. We are not burning product and we are not heating up the air around the shoots, simply the shoots themselves. No water is utilized (spraying) and no smoke is produced. Light contamination is restricted, however just for the duration of time in which action need to be taken due to frost.
— For how long can Frolight be set up? Is it a long-term system?
Throughout or after pruning, all set for the spring frost season. The setup time is around 3 hours per hectare which is comparable to setting up a control system with 1,200 m of IR tube. After the frost season we suggest eliminating your Frolight system for a longer life thanks to storage of nearly 10 months, less dangers of theft, vandalism, damage throughout works and so on. The taking apart time is around 1 hour for 2ha for a control system with 1200m IR tube (depending upon the kind of winder).
— What are the expenses per hectare of your system?
Challenging to address due to the fact that the expense depends upon the range in between the rows, the height of the plants, the length of the rows and so on. In basic we can state that Frolight as a financial investment expenses around 50-60 euro cents per direct meter each year.
I thank the developers of Frolight for addressing my concerns (this is not an advertorial) rapidly in spite of– they inform me– being overwhelmed by demands offered the episodes of the last month.
The environment is putting European wine makers to the test and I am significantly persuaded that innovation, a lot more than chemistry, can be a service (in addition to significantly high technical awareness) to reduce the crucial concerns that put whole harvests at threat every year. It’s a long stretch to state that this is the remedy for all ills however I invited this development with interest which appears to have currently had extremely favorable feedback worldwide. We’ll see … crossing our fingers and hoping that it will be required as low as possible.
