00:30The 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.

00:42Vineyards are not homogeneous units, OK?

00:45There are micro variations in microclimates, in soil.

00:49Even the plants are individual.

00:51So it is important for us to understand how each grapevine is actually living.

01:00Measuring production vine by vine is new here,

01:03and to make it possible, these 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.

01:19O objectivo é, durante a vindima, o trabalhador, durante o processo normal,

01:24nós conseguimos medir todos os cortes que ele faz com a tesoura

01:27e sincronizar o corte com a deposição das uvas no balde,

01:32que tem uma placa que permite medir o peso e os acréscimos de peso resultantes da vindima.

01:38O balde é também ele localizado por GPS,

01:42ou seja, permite-nos dar a localização de onde o corte e a deposição aconteceu na vinha.

01:48O 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 climate,

02:06and the amount of sun, rain, wind, 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

02:22and loaded onto the tractor, they're tracked en route to the cellars.

02:25and 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 grape vines

02:39that contributed for that reception tank volume.

02:44One 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.

02:54All 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 then the blockchain comes out and gives 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.

03:26The robot that we have here is able to navigate in these vines

03:28that have declines acentuados, as you can see here,

03:31and navigate in a safe way, without falling,

03:34and to navigate totally autonomous and safe,

03:37either for the vines, either for humans, or for animals.

03:43Robots in the vines offer the chance

03:45to gather even more data

03:46about how the plants are progressing.

03:48And if we have a robot that travels in these vines

03:51autonomously 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 in which state the temperature it was,

04:01which humidity it was exposed,

04:03and what type of treatment and fertilization

04:06has led to this uva.

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

04:13that can trace its journey from the bottle

04:15all the way back to specific grapes,

04:17harvested 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,

04:37from the plants, from the places,

04:39and then transfer those identity and quality

04:43into the product,

04:44into the wine that the consumer will enjoy.

04:47That'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.
