00:01Europe's best food safety experts are joining forces to crackdown on fraud.

00:06Euronews is following them in this special series called The Food Detectives.

00:10In this episode, the team committed to complete clarity in why.

00:23It's autumn in the Douro Valley in Portugal and there's something special about the harvest this year.

00:29These vineyards are at the heart of an effort to bring total traceability to winemaking

00:34and it begins with measuring the production of each plant.

00:38Food detective Antonio Graça explains why it's so important.

00:43Vineyards are not homogeneous units, okay?

00:46There are micro variations in micro climates, in soil, even the plants are individual.

00:52So it is important for us to understand how each grapevine is actually leaving.

00:59Measuring production vine by vine is new here and to make it possible,

01:04these food detectives from the EU's Watson project have developed two devices.

01:09One is a smart secateur and the other is a connected bucket, both robust enough for everyday use.

01:15They allow the winemakers to record exactly where and when the grapes were picked.

01:20The goal is, during the Vindima, during the process of normal,

01:25we can measure all the cuts that he makes with the knife,

01:28and synchronize the cut with the disposal of the vineyards.

01:32It has a plate that allows to measure the weight and the weight result of the vineyards.

01:38The vineyards is also localized by GPS,

01:42which allows us to show the location of where the cut and the deposition happened in the vineyards.

01:49The motivation for such precision is clear,

01:52to shed light on exactly how the grapes develop different qualities and why.

01:57It's really a detective work,

01:59because we have to look at all the leads that nature gives us.

02:03We have to understand the soil, we have to understand the climate,

02:07the amount of sun, rain, winds, solar radiation,

02:12that is actually what makes the plant work and produce what we want.

02:19Once the grapes are harvested from these vines and loaded onto the tractor,

02:23they're tracked en route to the cellars.

02:26And here, the information flow continues.

02:29The moment they come into the reception tank,

02:32they are assigned a code to that volume of grapes,

02:36from which we know all the individual grapevines

02:39that contributed for that reception tank volume.

02:43One of the key challenges is managing large amounts of information securely.

02:48So these food detectives are testing blockchain technology

02:51to record which vines grapes went into each bottle.

02:55All this information that is collected,

02:57the goal is that it contributes to the knowledge

03:00and guarantees the rasterability.

03:02But we also need to keep the information

03:04in a way that is reliable and unviolable.

03:08And that's when blockchain comes out.

03:10We give us this mechanism.

03:12Alongside blockchain, another emerging technology

03:15is slowly making its way into winemaking.

03:18This autonomous robot knows these vines well

03:21and is being tested as a tool to cut grass,

03:24prune the plants and spray.

03:26Robots in the vines offer the chance to gather even more data

03:46about how the plants are progressing.

03:49And if we have a robot that travels in these vines

03:52autonomously and frequently,

03:53we will be able to tell the story of each uva that exists in the vines.

03:58We will be able to understand what temperature it was,

04:01what humidity it was exposed,

04:04and what kinds of treatments and fertilization

04:06took this uva.

04:10The ultimate goal of this team is to produce wine

04:13that can trace its journey from the bottle all the way back

04:16to specific grapes harvested on a precise day

04:19on a particular patch of hillside.

04:22For winemakers, such traceability means a chance

04:25to better capture the character of each harvest.

04:28We can work better at generating quality,

04:33generating identity from the earth, from the plants, from the places,

04:39and then transfer those identity and quality into the product,

04:45into the wine that the consumer will enjoy.

04:48That's all for this episode.

04:49Next time on The Food Detectives,

04:51cracking down on counterfeit olive oil in Italy.

04:54See you then.

04:55The Food Detectives

04:59coming in.

05:00To the 볼

05:16to the seller of the industry in every year.
