What is the relation (in numbers) between grapes, vines, bottles of wine and hectares?

This was the homework question of last week.
The following numbers are rough figures.

How much wine per vine?
One kg of grape will produce, after fermentation, around 0.7 - 0,75 litres of wine. Icewine only 0,11 litres.
Weight per grape: 1,5-2 grams
Grapes per cluster (=bunch): 75-100 grapes
Weight of a cluster: 150 gram (makes 1 glass of wine)
Clusters per vine: 40 clusters
Wine per vine: 5-10 bottles
A bottle of wine contains 500-800 grapes.
It is theorized there are approximately 40-50 million bubbles in a bottle of sparkling wine/champagne.

How many bottles of wine per hectare?
The density of plantation per ha will be determined by the space between rows (1–3.6 m) and the space between vines (1–2 m). The density can vary from 3,000 vines per ha to 12,000 vines per ha.
Depending on the vine variety, density of plantation and pruning scheme, harvest could yield between 5 and 20 tons of grapes per ha.
Average yield: 60 hl/ha (=0,6 L/m2)

Costs of winemaking
Costs of processing grape juice into wine can vary significantly depending on the style of wine produced, e.g. early bottled wine, long-ageing wine, wine aged in barrels, etc.
On average, it is estimated that producing 1 litre of wine sold in a 75 cl glass bottle costs around 0.5–1.2 euros/litre. Ageing wine in new barrels would increase this cost by 1 euro/litre.

Measures and Conversions

Area
1 hectare = 2.471 acres = 10,000 square meters = 100 ares = 24 ouvrees
1 are = 100 square meters (100 ares = 1 hectare)
1 ouvrees = 4.285 ares = 0.417 hectares
1 journal = 8 ouvrees = 1/3 hectare (3 journeaux = 1 hectare)

Volume
1 hectoliter = 100 liters = 133.3 bottles = 11.1 cases
1 queue = 2 tonneaux = 456 liters = 608 bottles
1 tonneaux = 1 piece = 228 liters = 304 bottles (Standard Burgundy cask)
1 feuillette = 1/2 tonneaux = 114 liters = 152 bottles
1 quarteau = 1/4 tonneaux = 57 liters = 76 bottles

Quarter bottle – Split or Piccolo (187.5 or 200 ml) – Just itty-bitty
Half bottle – Demi (375 ml)
Bottle – Imperial (750 ml) Standard
Magnum (1.5 liters) Equal to 2 bottles.
Jeroboam (3 liters) Equal to 4 bottles.
Rehoboam (4.5 liters) Equal to 6 bottles.
Methuselah (6 liters) Equal to 8 bottles.
Salmanazar (9 liters)12 bottles.
Balthazar (12 liters) 16 bottles.
Nebuchadnezzar (15 liter) 20 bottles.
Melchior (18 liter) 24 bottles.
Solomon (25 liter) 33.3 bottles
Primat (27 liter) 36 bottles.
Melchizedek (30 liter) 40 bottles.

Exotic European grapes in South America

16 May 2014, Claudia prepared an excellent dinner for Weber, Ronaldo, Malafa & Clea, and Rolf. Included: spanish dried sausages that Clea brought, zucchini with gorgonzola, fondue with ementhaler and homemade bread, pear with homemade nutella and chilli.
The Argentinian/Brazilian wines were from uncommon grapes:  arinarnoa, teroldego, bonarda.

Arinarnoa
Arinarnoa is a dark-berried wine grape variety, bred in 1956 as a crossing of two Bordeaux varieties. It combines the rich and fleshy Merlot with the acidity and spice of Petit Verdot. The wines are naturally deep in color and well structured – unsurprising, given its pedigree.
Grown mainly in the south of France for the Vin de Pays/IGP designations of the Languedoc and Provence, Arinarnoa has spread as far as South America, where varietal examples are made in Argentina, Brazil and Uruguay.

Teroldego (pronounce: tehr-AWL-deh-go)
Teroldego is a deeply colored red-wine grape grown in the Trentino-Alto Adige wine region of northern Italy. There is just one DOC for Teroldego (Teroldego Rotaliano) in its native Italy, and the variety is hardly cultivated anywhere else in the world. The Teroldego Rotaliano wines, from the flat, triangular-shaped plain of the Adige Valley, are made exclusively from local Teroldego grapes.
Teroldego produces deeply pigmented red wines with an intensely fruity characteristic, a style that has become something of an
The variety has recently been identified as one of the parents of Lagrein.

Bonarda
Bonarda is the name used for four entirely distinct red wine grape varieties; three from northern Italy and one from Argentina.
The oldest is Bonarda Piedmontese. This is an aromatic variety, now near extinction but it once rivaled Barbera and Nebbiolo in the vineyards of western Piedmont. Although quite capable of producing distinctive wines of good quality, it was replanted only sparsely after the phylloxera epidemic of the 1880s. This is most likely because Bonarda Piedmontese vines offered only very low yields, and winegrowers at that time took a pragmatic, economic approach as they sought to re-establish their vineyards.
The other two Bonarda vines are also from northern Italy, and both are currently used in the Po Valley. Here it is mostly known as Croatina – its name refers to its origins in Croatia – although it has often gone under the name "Bonarda" in southern Lombardy, most notably in the Oltrepo Pavese DOC. There are now even varietally labeled Oltrepo Pavese Bonarda wines, including a sparkling frizzante version, made from Croatina. Croatina is also used slightly further down the Po Valley, in the Colli Piacentini hills of western Emilia-Romagna.
Uva Rara is the third Italian "Bonarda" grape, also known as Bonarda Novarese (after Novara, a Piedmontese town located just south of Lake Maggiore). Like Croatina, Uva Rara is used in Oltrepo Pavese wines, but goes under its Uva Rara title. As suggested by its name, Uva Rara was once a rare vine here, although it is now one of the key red varieties around Pavia.
The majority of Bonarda grapes grown in the world are planted in Argentina, rather than Italy. Here, the grapes are used both in blends (often with the Argentine icon Malbec) and in varietal wines. The Argentine version of Bonarda is also known as Charbono, which has itself been confused with various varieties.
Popular blends include: Bonarda - Malbec.

Wine as an antiseptic

CAN YOU GET ILL FROM TAKING THE COMMUNION CUP?

Contrary to popular opinion, wine, and other beverages of antiquity produced through fermentation, were probably more important in providing disease-free drinking fluids than in their tendency to intoxicate. Ancient Greeks drank their water mixed with wine, and also used wine to cleanse wounds and soak dressings. More recently, military physicians of the last century observed that during epidemics of cholera, wine drinkers were relatively spared by the disease, and troops were advised to mix wine into the water.

Wine has been shown to be an effective antiseptic even when the alcohol is removed. In fact, 10% alcohol is a poor antiseptic, and alcohol only becomes optimally effective at concentrations of 7;0%. The antiseptic substances in wine are inactive in fresh grapes because these molecules are bound to complex sugars. During fermentation these antiseptic substances are split off from the sugars and in this way become active. These molecules are polyphenols, a class of substances used in hospitals to disinfect surfaces and instruments. The polyphenol of wine has been shown to be some thirty-three times more powerful than the phenol used by Lister when he pioneered antiseptic surgery.

Same year wines can be diluted up to ten times before beginning to show a decrease in their antiseptic effect. The better wines gradually improve with age over the first ten years and can be diluted twenty times without a decrease of the antiseptic effect. This effect then remains more or less constant over the next twenty years and becomes equivalent to a new wine after another twenty-five years. (Modern antiseptics and antibiotics for disinfecting wounds have surpassed wine effectiveness because the active ingredients in wine are rapidly bound and inactivated by proteins in body tissues.)

In preparing communion, the hot water that is added to the wine will increase greatly the antiseptic effect of the polyphenols. Disinfection occurs more rapidly and more effectively at 45 degrees centigrade than at room temperature (22-25 degrees). Another contribution to the antiseptic effect comes from the silver, copper, zinc that make up the chalice itself, ensuring that microbes are unable to survive on its surface.

Throughout the centuries, no disease has ever been transmitted by the taking of Holy Communion. Diseases, such as Hepatitis B, known to be transmitted by shared eating utensils, have never been acquired from the communion spoon. HIV is known not to be transmitted through shared eating utensils, and considering the antiseptic qualities of the Holy Communion received by the faithful, there is no likelihood of acquiring HIV infection through the Common Cup.
