1
The wash process, sometimes known as wet process, is commonly found in many coffee growing countries around the world,
2
including parts of Africa and most of Central and South America.
3
The methods and equipment used to perform this type of processing are different from place to place, but the design remains universal.
4
It's designed to remove the coffee fruit from the coffee seed quickly
5
and thoroughly after the coffee is picked so that it can be dried clean in its parchment layer. In this video,
6
we'll be exploring just one example of the wash process by
7
following along with a producer washing his coffee in the highlands of Peru.
8
Generally speaking, the wash process can be an efficient way to prepare coffee seeds for export in climates
9
that have cool overnight temperatures and good sun exposure during the day.
10
It's also a space saver for small producers who do their own wet milling
11
and some of their own drying on their property, as we'll see in this video from Finca Ecologica.
12
To begin, coffee is harvested ripe when the coffee is dark red, bright red, purple, or yellow, depending on the variety or cultivar.
13
The cherry is selectively picked by hand and carried to a receiving point.
14
At this farm, the cherry is delivered to an area around a small mechanical depulping machine, which is equipment commonly found on farms in Latin America.
15
Before being depulped, it's weighed, rinsed, and given a first sort for quality.
16
Some producers do what's called a float test of their coffee cherries.
17
They submerge the cherries in water and scoop off any cherries that float to the top of the tank, which is a sign of a defect.
18
Whole coffee fruit is then put through the depulper.
19
This machine squeezes the seed out of the tough, cherry -like skin, which is known as the fruit's pulp.
20
Depulping typically happens as soon as possible in the washed process, usually within 8 to 12 hours of the harvest.
21
After depulping, the seeds are still covered in their sticky fruit material, which is called mucilage.
22
This mucilage is removed throughout the washing process.
23
The sticky seeds are typically transferred to a fermentation tank.
24
The pulp leftover is usually used for compost or fuel, or it's discarded.
25
Here you can see that the fermentation tank is made from ceramic tile,
26
and the coffee is collected in a pile in the bottom of the tank.
27
In this case, the sticky seeds are kept dry in an open fermentation style, which means they're not submerged in water during the fermentation.
28
The seeds will be left like this overnight to ferment in the tank.
29
Fermentation happens in every type of post -harvest processing, but in the wash process the producer tries to moderate the time
30
and temperature as well as the velocity of the fermentation process.
31
Fermentation is useful because it will help soften the fruit mucilage making it easier to remove in the washing.
32
The next day, the actual washing begins.
33
The producer first makes sure
34
that the mucilage has fermented enough by inspecting a sample with his hands to feel how sticky or tacky the material is.
35
He then fills the tank with fresh water to submerge the coffee.
36
While the coffee is still submerged, he'll agitate it with a long wooden tool.
37
The vigorous agitation in the water removes the mucilage, leaving the coffee clean in its parchment layer and ready for drying.
38
You can see how the water becomes murky as it starts to fill with mucilage material.
39
Farmers often repeat the process of washing the coffee by draining the murky water out
40
and refilling the tank with fresh, clean water.
41
The water used in this process needs to be purified, treated, or disposed of very carefully.
42
The fruit mucilage left behind from the washing will contaminate fresh water or groundwater sources if it's not handled properly.
43
On this farm the producer washes his coffee three times.
44
While the tank is full of water he also removes any seeds
45
that float to the top which is a sign that they are damaged or defective.
46
Once the seeds are clean from mucilage, this producer does another quality sort.
47
He brings the washed coffee to the drying patios
48
and uses a portable sorting table that allows him to remove any of the remaining coffee cherry husks, as well as defective or deformed beans.
49
Not all producers use tools like this, but some places like Peru, Costa Rica, and Colombia, this is a fairly common practice.
50
Here you can clearly see the uniformity of the coffee that has passed through the sorting device.
51
After the final sort, the producer brings the washed coffee to the drying surface and spreads it out.
52
In this case you can see that the coffee is being dried on tarps on a wooden patio under a plastic cover.
53
The drying environment is designed to control the temperature and airflow in order to dry the coffees efficiently while preserving the quality.
54
The seeds are spread into a thin layer on the patio using a wooden rake.
55
The coffee will be raked several times a day throughout the drying process to ensure that it dries evenly.
56
This happens until it reaches an internal moisture of about 11%, which can take up to one or two weeks depending on the weather.
57
After the coffee's dried, it's transported to a storage unit
58
or a warehouse in its parchment layer where it will rest in sacks until it's ready to be exported.
59
Then the parchment will be removed and the coffee will be shipped.

इस पाठ की शब्दावली और बोलने के सुझाव
यह स्पीकिंग पाठ वीडियो “Washed Coffee Processing” पर आधारित है। सबसे ज़्यादा दोहराए गए शब्द ये हैं: coffee, seed, process, producer, mucilage। इस वीडियो में शैडोइंग के लिए 45 वाक्य और 934 शब्द हैं। बोला गया हिस्सा 6:08 लंबा है। वक्ता लगभग 152 शब्द प्रति मिनट की स्वाभाविक गति से बोलता है, जो रोज़मर्रा की बातचीत के करीब है। केवल 77% शब्द अंग्रेज़ी के 3,000 सबसे आम शब्दों में से हैं, इसलिए शब्दावली कठिन है।

इस वीडियो का व्याकरण
वक्ता जिन संरचनाओं का सबसे अधिक प्रयोग करता है, वीडियो के असली शब्दों के साथ:
| संरचना | वीडियो में |
|---|---|
| Passive voice be + past participle — ज़ोर इस पर कि क्या होता है, न कि कौन करता है | is commonly found · is picked · is harvested |
| Relative clauses who / which + उपवाक्य — व्यक्ति या वस्तु के बारे में अतिरिक्त जानकारी | machine, which is · tank, which is · skin, which is |
| Present perfect have/has + past participle — बीता हुआ काम जिसका असर अभी भी है | has fermented · has passed |
ध्यान देने योग्य उच्चारण
वक्ता 3 बार संक्षिप्त रूपों का प्रयोग करता है, जैसे we'll, they're। इन्हें वैसे ही छोटा बोलें जैसा आप सुनते हैं।
- “th” की ध्वनियाँ: thin /ˈθɪn/, thoroughly /ˈθʌɹ.ə.li/
- “sh” और “zh” की ध्वनियाँ: wash /wɑʃ/, exposure /ɪkˈspəʊ.ʒə(ɹ)/, efficient /ɪˈfɪʃənt/, freshwater /ˈfɹɛʃˌwɔːtə(ɹ)/, fermentation /ˌfɜɹmənˈteɪʃən/
- लंबे शब्द — बलाघात सही रखें: universal /ˌjunəˈvɜɹs(ə)l/, mechanical /məˈkænəkəl/, velocity /vəˈlɑsəti/, fermentation /ˌfɜɹmənˈteɪʃən/, agitation /ædʒ.ɪˈteɪ.ʃən/
हिंदी भाषियों के लिए मुश्किल ध्वनियाँ:
- /v/ और /w/ का फ़र्क़ — /v/ में ऊपर के दाँत निचले होंठ को छूते हैं, /w/ में होंठ गोल होते हैं: wash /wɑʃ/, wooden /ˈwʊdn̩/, harvest /ˈhɑɹ.vəst/, overnight /əʊvə(ɹ)ˈnaɪt/, defective /dɪˈfɛktɪv/
- /z/ — इसे “ज” (/dʒ/) न बनाएँ: preserve /pɹəˈzɝv/, squeeze /skwiːz/, dispose /dɪsˈpoʊz/
- शब्द की शुरुआत में s + व्यंजन — पहले “इ” न जोड़ें: sticky /ˈstɪki/, squeeze /skwiːz/, scoop /skup/
इस वीडियो से अभ्यास कैसे करें
- पहले बिना बोले पूरा वीडियो एक बार सुनें और जो शब्द नहीं आते उन्हें लिख लें।
- 0.75× गति से शुरू करें, एक-एक वाक्य की शैडोइंग करें, और सहज लगने पर सामान्य गति पर लौटें।
- अपनी आवाज़ रिकॉर्ड करें और मूल से तुलना करें, ख़ासकर wash, seed, cherry जैसे शब्दों पर ध्यान दें।
शैडोइंग तकनीक क्या है?
शैडोइंग (Shadowing) एक विज्ञान-समर्थित भाषा सीखने की तकनीक है जो मूल रूप से पेशेवर दुभाषिया प्रशिक्षण के लिए विकसित की गई थी। विधि सरल लेकिन शक्तिशाली है: आप मूल अंग्रेज़ी ऑडियो सुनते हैं और तुरंत इसे ज़ोर से दोहराते हैं — जैसे वक्ता की छाया 1-2 सेकंड की देरी से। शोध से पता चलता है कि यह उच्चारण सटीकता, स्वर, लय, जुड़ी हुई ध्वनियाँ, सुनने की समझ और बोलने की प्रवाहशीलता में काफ़ी सुधार करता है।
