As cli­mate change has emerged among the most urgent global chal­lenges, ABC News set out to see how global warm­ing and its some of its side effects impact Ital­ian olive oil pro­duc­tion in its Food Fore­cast series.

No mat­ter what chal­lenge they are faced with, they will sur­vive because of their pas­sion for that age-old tra­di­tion.- Gin­ger Zee, ABC News

The jour­ney is intro­duced by feeds from a drone fly­ing over an olive grove in Agri­gento, where Olio Taibi pro­duces an award-win­ning mono­va­ri­etal of Nocel­lara del Belice.

Olive Oil Times con­sulted ABC News for the episode of the series hosted by ABC News chief mete­o­rol­o­gist Gin­ger Zee, who trav­eled with her crew through the Mediter­ranean coun­try to meet pro­duc­ers and sci­en­tists dur­ing the 2016 har­vest.

As Zee said, over the past few years across the globe, but defin­i­tively in Italy, there have been major chal­lenges which led to a decrease in pro­duc­tion, most of which were due to the weather.

What we are see­ing right now in Italy is the effect of drought,” Olive Oil Times pub­lisher Cur­tis Cord observed in an inter­view last year at the Inter­na­tional Culi­nary Cen­ter. Out­breaks of pests such as the olive fruit fly and other dis­eases are mainly caused by adverse cli­matic con­di­tions — a key player in the never-end­ing bat­tle” faced by pro­duc­ers.

Despite the dis­rup­tive effects of cli­mate and count­less other head­winds, Ital­ian pro­duc­ers nev­er­the­less man­age to main­tain qual­ity at the high­est lev­els.

It is har­vest time and the ABC News cam­era pans over an orchard in Tus­cany, where olives are picked and deliv­ered to the mill. At Olio del Colle, extra vir­gin olive oil pours out of the steel tube which com­pletes the top-of-the-line process in full swing. I’ve defin­i­tively never had fresh olive oil until right now,” Zee reveals — the sound of the machin­ery in the back­ground — while savor­ing a drib­ble extra vir­gin olive oil on a slice of bread with the pro­ducer Flavia Pao­letti.

From the tree to your table extra vir­gin olive oil should be sim­ple,” Gin­ger Zee affirms. Extra vir­gin olive oil has to be free of what we call defects,” Cord echoes back in New York, where they taste an intense fruity extra vir­gin olive oil which expresses itself with a pun­gent sen­sa­tion.

There is also the health aspect of it, which is really the most impor­tant part,” Cord points out. We pay more for extra vir­gin olive oil because we expect that it has a cer­tain taste and cer­tain health qual­i­ties.”

From low­er­ing the risk of heart dis­eases to ben­e­fit­ing lev­els of blood sug­ars, the health claims are unde­ni­able,” Zee explains onsite at a Brook­lyn olive oil retailer, O‑Live.

The next stop in Italy is Santa Téa farm, where this reporter meets the group to which I pro­vided some logis­ti­cal sup­port. Ser­ena and Gior­gio Gonnelli take us to groves located on the hills between Flo­rence and Siena to expe­ri­ence the fever­ish activ­ity that is tak­ing place among trees of Lec­cino, Fran­toio, Moraiolo, Cor­reg­gi­olo and Lec­cio del Corno.

Olives are col­lected with elec­tric rakes with car­bon fiber arms and crushed in a few hours. I do think peo­ple have no idea how much effort and money it costs,” Zee real­izes after using the har­vest tool and gath­er­ing olives with the nets with the group of work­ers.

It takes time, labor costs and pro­duc­tion costs. That is why a bot­tle of authen­tic extra vir­gin olive oil can­not be cheap,” Gonnelli observes. How­ever, I think that the mar­ket is chang­ing, and con­sumer are get­ting closer and closer to olive oil,” the pro­ducer con­sid­ers.

At the ancient mill of the farm that dates back to 1426 you could still use gran­ite mill­stones to crush olives, but despite the fas­ci­na­tion with this antique machine, high-qual­ity extra vir­gin olive oil is now pro­duced with the lat­est tech­nol­ogy.

Two years ago, the sea­son started with ideal cli­matic con­di­tions which Zee refers to with an Olive Oil Times report of that period; but then sum­mer turned out to be very hot and humid and pro­duc­tion decreased. The weather is chang­ing and it’s chang­ing very fast,” Gonnelli con­cludes.

Luigi Ponti, ento­mol­o­gist at ENEA Casac­cia Research Cen­ter, says the hope is that this one (2016/2017) will be a good sea­son, based on the prin­ci­ple of bio­log­i­cal alter­na­tion. The olive fruit fly is a pest that is mostly dri­ven by weather,” he affirms. In gen­eral, you have nat­ural ene­mies which con­trol the pop­u­la­tion of agri­cul­tural pests, but in this case, that is not what hap­pens because it is a very pro­lific ani­mal. There isn’t a nat­ural enemy that is effec­tive enough.”

What­ever affects the fly is weather-related, as Ponti evi­denced in a study esti­mat­ing that by 2060 an increase in tem­per­a­ture in the Mediter­ranean would lead to an incre­men­tal increase of olive oil pro­duc­tion in Italy and France but also to a growth of olive fly infes­ta­tions.

If you want to make qual­ity you’ve got to spend,” points out Marina Colonna, inter­viewed by the ABC News team at her farm in Molise. She recently planted new olive trees of local vari­eties and con­tin­ues to pro­duce high-qual­ity olive oil despite the threat of the olive fruit fly and other pests.

Colonna presents her olive trees bear­ing healthy fruits. If you don’t want to spend, then it is your risk. And today, you can­not risk, because cli­mate change is so much, that you have to be really care­ful,” she con­tin­ues. You have to watch your trees all the time — if you care for them. If you don’t care… any­thing can hap­pen,” Colonna declares.

Prob­a­bly related to effects of cli­mate, Xylella fas­tidiosa is a big issue” with plenty of con­tro­versy sur­round­ing how to deal with it, Zee notes.

It is a multi-fac­to­r­ial thing where weather, soil fer­til­ity and fungi play a role,” Ponti explains. Now, we are see­ing its spread in Cor­sica and Majorca and it has been found in other places,” Cord remarks. It is some­thing that the sci­en­tific com­mu­nity and the agri­cul­tural com­mu­nity is pay­ing atten­tion to. And hope­fully, they will be able to pre­vent this seri­ous out­break. But, who knows.”

Despite these cir­cum­stances, the price of olive oil might not be affected as directly as most peo­ple think due to the stocks that larger pro­duc­ers hold to be released when the mar­ket con­di­tions require, Cord explains. But this leads to old olive oil in the mar­ket that often isn’t as fresh as the labels indi­cate. There is a har­vest date, and if you can find that, that’s the best indi­ca­tion for the true shelf-life or the true fresh­ness,” Cord rec­om­mends.

More and more pro­duc­ers are putting the har­vest date on the bot­tle, Cord sug­gests as he and Zee are sur­rounded by olive oil bot­tles at a Fair­way Mar­ket in Chelsea. This at least give you a leg up and it is bet­ter­ing your chance of actu­ally get­ting a high-qual­ity extra vir­gin olive oil. At least, it makes sure it is fresh. Once you do that, then you learn how to taste it.”

Then, back at the Culi­nary Cen­ter, he pours some olive oil in two blue glasses that, accord­ing to the label, should be an extra vir­gin olive oil but turns out to be ran­cid. What you have here is some­thing very typ­i­cal that most of us are eat­ing every day,” says Cord.

The solu­tion is sim­ple and lies in pur­chas­ing high-qual­ity extra vir­gin olive oils, just like those made by the pro­duc­ers that Zee met dur­ing this jour­ney through Italy, which are able despite the dif­fi­cul­ties to achieve excel­lence.

For me, I was lucky enough to expe­ri­ence the taste of real extra vir­gin olive oil in Italy, and after my jour­ney, real­ized that, no mat­ter what chal­lenge they are faced with, they will sur­vive because of their pas­sion for that age-old tra­di­tion,” Zee con­cludes, while hav­ing a slice of bread with a drib­ble of high-qual­ity extra vir­gin olive oil.
