At about 11 a.m., which is colazione time (a shortmidmorning break halfway between breakfast and lunch), peoplecommonly treat themselves to anespressoaccompaniedbya littlepastry.Athome,Italiancaffèmokareignssupreme.TheItaliansdonotdrinkfiltercoffee.
INSCANDINAVIA(NORWAY,SWEDEN,ETC.)
TheScandinavians are theworld’s biggest consumers of coffee,which isdrunk predominantly in the form of filter coffee. In nineteenth-centuryNorway itwas common for people to produce their own spirits at home.Before long, to combat alcohol consumption, the Church decided topromote a less dangerous drink: coffee. Andwhen home distillationwasbanned, coffee consumption became the norm, and has remained so eversince.
INTURKEY
The technique used tomakeTurkish coffee (known as “Greek coffee” inGreece) can be traced back to the sixteenth century and the OttomanEmpire.Itinvolvessimmeringcoffeegroundasfineasflourwithwaterinacezve, a traditional long-handledcopperorbrasspot.

To combat thistrend, various initiatives have been put in place, including “fair trade,”whichensuresthatcoffeefarmersareabletoearnadecentincome.
Fairtrade
FairtradecertificationFair trade certification was set up in the Netherlands in 1988 by the MaxHavelaarFoundationwiththeaimofguaranteeingapurchasepricedeemedfairforsmallcoffeeproducers.Ifpricestrenddown, thefair tradelabelguaranteesproducers a minimum amount that they can live on. If prices rise above thebenchmark,thepricewillthenbeincreasedbyapredeterminedvalue.

CONTROLLINGTHEFINENESSOFTHEGRIND2
Thefinenessofthegrind(orgrindsize)isafundamentalvariablethatcanbe adjusted according to the desired result and other parameters. Theespresso extraction time and the coffee balance are affected by thetemperature and humidity of the air. Hence the barista has to adjust thegrindsizeseveraltimesaday.Thisiswhyitisnotadvisabletobuycoffeethathasalreadybeengroundtoacertainfixedgrindsize.
TherightgrindforeachbrewingmethodDifferentmethodsofbrewingcoffeerequiredifferentgrindsizes.Adjustingthegrind size allows you to vary the speed of extraction of the coffee’s flavormolecules.The finer thegrind, thegreater the surfacearea incontactwith thesolvent—in this case, water—and the faster the coffee components dissolve:espresso needs fine-ground coffee to compensate for the fact that the brewingtimeisshort(lessthan30seconds),whereasaFrenchpress,withitsfour-minuteinfusingtime,requiresacoarsegrind,whichhelpskeepbitternesstoaminimumandlimitstheamountofsedimentinthecup.

THELONGHISTORYOFASHORTCOFFEE
Thishighlyfashionablebrewingmethodwasinventedin1820,thebrainchildofaFrenchman,LouisBernardRabaut,beforebeingpopularizedandrefinedbytheItalians.
Theideaofusingsteamtoforcehotwater throughdark-roasted,finelygroundcoffeebeanscamefromaFrenchman,LouisBernardRabaut.
This conceptwas put into practice by another Frenchman,ÉdouardLoysel deSantais, for the firstUniversal Exhibition in Paris in 1855, in the form of hishydrostatic percolator, capable of delivering large volumes of coffee, tea, orevenbeerinrecordtime.
At the Turin exhibition in 1884, the Italian entrepreneur Angelo Moriondoexhibitedhis“steammachinery for theeconomicand instantaneousconfectionofcoffeebeverage,”forwhichhewasawardedthebronzemedal.Atthetimeitwasn’t yet known as an espresso machine, but several such machines wereproducedforuseinhisfamily’shotelsandrestaurants.
Theyear1901sawthearrivaloftheTipoGigantebyLuigiBezzera,andofitsnear identical twin, the Ideale by Desiderio Pavoni, the first real espressomachineswithaportafilterthatbrewedindividualcups.
In1947,AchilleGaggiaandhisleverespressomachineenabledthepressuretoberaisedfrom1.5 to9bar, resulting in theproductionofcrema,whichhadn’tappearedbeforethattimebecausetherewasn’tsufficientpressure.
AFAIREXCHANGE
It may have been the Italians who refined and set thestandards for espresso, but, contrary to popular belief, thefamousdrinkneverthelesshaditsrootsinFrance.Itisworthnoting, though, that it was following that same UniversalExhibition in Paris in 1855 that the sixty-two Bordeaux“crus” were awarded their official classification, when thefact is thatwinehad itself been imported intoGaul by theRomans.
THELOYSELMACHINE
ASPOTOFVOCABULARY
The term “percolator” comes from the English verb“percolate,” itself derived from theLatin verb “percolare,”meaning“topassthrough,tofilter.”Theterm“hydrostatic”indicates that the extraction pressure is produced by theweightofacolumnofwater(1barforevery10meters).
EXPRESSOORESPRESSO?
The name “expresso” derives from “express,” meaningrapid.With the exception of a few European and French-speaking countries, the “espresso” variant, probably takenfrom the Italian pressione, “by pressure,” is much morecommon. Nowadays the term “expresso” tends to be usedforacoffeeofabout2floz(alsocalledtwo-thirdsofacupinFrench),whereastheterm“espresso”isreservedfora1floz short coffee.And as the Italian style of coffee-drinkingtendstoprevail,theterm“espresso”isconsideredcorrect.

BUTWHATISPRESSURE?
Pressure is a force that acts on a surface. Its unit ofmeasurement is the bar, with 1 bar equal to the pressureexerted by a mass of 1 kg on an area of 1 cm2.We findexamples of different pressure levels in daily life:atmospheric pressure, that is, the pressure of the air thatsurrounds us (approximately 1 bar); submarine pressure,which increases by 1 bar for every 10 m (33 ft) you godown;cartirepressure(2bar);publicworkswaterpressure(3bar),etc.

ImmersionTheprincipleistomixthegroundcoffeewithhotwaterinacontainer,thenleave themincontact foracertainamountof time(betweenoneandfourminutes, depending on the method used). They are then separated toproduce a drinkable coffee. Thismethodmakes for easy, even extractionbecause the coffee particles infuse uniformly in the water, and does notrequireanyparticularskills.
FiltrationThis method involves extracting the coffee from the grounds, which areheld in a filter.The hotwaterwets and passes through the grounds, thenthrough the filter. The liquid containing the aromatic compounds and theoils runs down, under the effect of gravity, into a container placedunderneath,while the damp grounds remain in the filter. Contrary to theimmersionmethod,where the coffee/water contact time is controlled, thebrewingtimebythefiltrationmethoddependsonthespeedwithwhichthewaterispouredintothefilterbasket,andthefinenessofthecoffeegrounds.To ensure an even extraction, it is important to see that the grounds areuniformlywettedthroughouttheprocess.

PropagationThereare twowaysofpropagatingnewcoffeeplants:bytakingcuttingsorbysowingtheseeds.
CuttingsThis involves cuttingoff a smallpieceof the coffeeplant (the tipof abranchwithtwoleavesonit,andeachleafcutinhalf)andplantingit.Whennewleavesand roots form, the cutting has taken, and develops in the same way as aseedling. Since taking cuttings is a form of cloning, each new plant will begeneticallyidenticaltotheplantfromwhichthecuttingwastaken.

Pollination is essentially accomplished by the wind, sinceCoffeaarabica isaself-pollinatingshrub.Insectsonlyplayaminorroleinfertilization(between5and10percent).
Coffeeflavorsbyaltitude
The cooler climate at high altitude causes the cherries to ripen more slowly,resulting in denser beans. Broadly speaking, this means that the higher thealtitude at which the coffee is growing, the greater its acidity, the fuller itsaromas,andthebetteritstaste.

GrowingorganiccoffeeOrganic farming is relatively rare incoffee-producingcountries,where theuseof pesticides is the norm. Unfortunately, from a flavor perspective, organiccultivationdoesnotenhancethequalityofthebrew.Therefore,flavordoesnotcount as a reason for a farmer to change his approach. However, in somecountrieslikeEthiopia,small-scalegrowersdonotuseanyinputsbecausetheyare too expensive,whichmeans that they practice organic farming by default,without being officially certified. In Brazil, the world’s number one coffee-
producing country, some producers, like Fazenda Ambiental Fortaleza, growcoffeebyorganicmethods.
EnemiesofthecoffeeplantThere are various natural organisms that attack Coffea arabica, but its twobiggestenemiesarethefungusthatcausescoffeeleafrust(Hemileiavastatrix),andthecoffeeborerbeetle(Hypothenemushampei).
CoffeeleafrustDiscoveredinSriLankainthenineteenthcentury,coffeeleafrustisnowfoundin virtually all coffee-producing countries.

Whatisavariety?The variety is a botanical classification on a lower level than species. TheCoffeaarabicaand theCoffeacanephoraare twospeciesofcoffeeplant.Avarietyisasubgroupofindividualsthatdisplaydifferences(intermsoftheir
morphology,thesizeofthefruits,etc.)relativetothestandardvariety,which,in the case of the Coffea arabica, is the Typica variety. These differentvarietiescomeaboutasaresultofeithermutationorhybridization,dependingonthecase
MutationAmutation refers tomorphological changes in ayoungplant relative to thestandard variety (size and/or shape of plants, leaves, cherries). The mutantseedlings are considered to be a new variety if they keep their newcharacteristicswhentheyproduceseedsoftheirown.
HybridizationA hybrid is a cross between two varieties. Hybridization can be natural orartificial.
THECASEOFROBUSTA
Inactualfact,Robustaisnotitselfaspeciesofthecoffeeplant, but a variety ofCoffea canephora.How-ever, thedesignationCoffeacanephora iscommonlyusedtorefertoRobusta, the reasonbeing thatRobusta is theoriginalandmostwidelycultivatedvarietyof thosebelonging tothe Canephora species (the other consumable varietiesbeingKouillou,Conilon,Gimé,andNiaouli).

The coffee then develops a morenoticeablewoody flavor, its acidity declines, and it emits an odor resemblingburlap sacks. In this case one can refer to the coffee as having an “old crop”flavor profile. The green coffee from a harvestmay become “old crop” if thedrying, storage in the country of origin, transport, or storage after roasting isperformedinpoorconditions.

Brazil’s coffee-growing areas are for the most part located in thesoutheastofthecountry.Thecountry’ssize,climate,topography(aflatcountrywith gentle hill slopes, which, importantly, makes it possible to employmachinery), and altitude have enabled it to develop intensive coffee-farmingoperations. It has nearly 300,000 coffee farms, including vast estates usingmodern industrialmethods that improveproductivityandprofitability,butalsoorganic and even biodynamic farms that use fewer chemicals and endeavor topromote biodiversity on their plantations. It is possible to trace very goodBraziliancoffeelotsallthewaytotheindividualplantation.ItwasinBrazilthattheCupofExcellencewasinstitutedin1999.

So producers tend to focus on the quality oftheir output. Only Arabica varieties are cultivated. In 1960, the New Yorkadvertising agency Doyle Dane Bernbach (now know as DDB Worldwide)invented the figure of JuanValdez, the fictional character on the “ColombianCoffee”qualitylabel.Thisromanticimageofthehumblecoffeeproducerwithhis mule did much to enhance Colombian coffee’s reputation for quality.Nowadays coffee only accounts for 10 percent of the country’s exports, but itremainsastrongmarkerofnationalidentity.

The producers thenswitched to growingRobusta,which hasmuch better resistance to this fungaldisease. Nowadays, the large majority of the coffee produced in Indonesia isRobusta. Ninety percent of the coffee plantations in the archipelago areextremelysmall insize(2 to5acres).ThemostcommonlycultivatedvarietiesareTypica,HibridodeTimor(commonlyknownas“Tim”inSumatra),Caturra,andCatimor.

KOPILUWAK
Thesearecoffeebeansharvestedfromthedroppingsofthecivet cat (called luwak in Indonesia). These mammals ofSoutheastAsiaeatcoffeecherries,digestthepulp,andexpelthe beans in their excrement. This discovery dates back tothe eighteenth century, when the Indonesian plantationswereownedby theDutch,whobanned local farmers fromconsumingthecoffeebeans,whichweredeemedapreciouscommodityand, at the time, intended for consumers in theWest. So by harvesting coffee beans that had beenpredigestedbycivets, farmerswereable tocircumvent thisban.This typeofcoffeeexhibitsaparticular flavorprofile (it issaid to be sweeter and richer) on account of fermentationthatoccursduringthedigestionphase.Kopi luwak is today part of global coffee folklore, and itssuccesshaspromptedsomeunscrupulousproducerstokeepcivets in cages and feed them coffee cherries (and notalways the right kind) so as to generate more predigestedcoffee in order to meet market demand.
