MAKING GLASS BOTTLES

The entire process of bottle making is almost fully automated. An automated feeder separates a stream of molten glass into individual gobs by cutting it with what is,effectively, a giant scissors. These gobs are then dropped through tubes in a moving track. The gob is shaped into what looks like a short bottle with thick walls and is called a parison. The parison is transferred to a final mould made of iron, which moves up and clamps around the glass. Air is blown into the glass until it acquires the final shape of the mould. This procedure involving expansion is called blowing. The bottle is then released from the mould and annealed.

Annealing is done by reheating the glass and gradually cooling it. This process removes the stresses and strains in the glass after shaping. This is a most important step and if not done the bottles can explode on contact with a hard object (like another bottle) as a result of the build up of tension caused by uneven cooling. After the bottles have cooled to room temperature, they are inspected and finally packaged. 

Glass

Glass is made by melting together several minerals at very high temperatures. Silica in the form of sand is the main ingredient and this is combined with soda ash and limestone and melted in a furnace at temperatures up to 1700oC. Other materials can be added to produce different colours or properties. Glass can also be coated, heat-treated, engraved or decorated.

Shirdley Sand is a vast swathe of sand deposited by wind since the last glaciation. It spreads from the Sefton Coast several kilometres inland, and can create dunes up to 75m (246ft) tall.

The sand, centred around the hamlet of Shirdly Hill was an invaluable resource as an ingredient in glassmaking hence the location of the UK major glassmaking facilities in St Helens. As late as the 1970s the fields around Bickerstaffe and Lathom were still being excavated for the pure Shirdley Hill sand by the Pilkington Brothers Glass Company whose international research facility is situated at Lathom.

Shirdly Hill, situated about 5km (3 miles) south-east of Southport is now flat !

Piccolo (1/4 bottle) 187ml
Italian for ‘small’. 187ml is approximately two glassfuls – Champagne glasses usually hold around 125ml but it is not usual to fill them.

Demi (1/2 bottle) 375ml
French for “half,” and also known affectionately as a ‘Fillette’, or ‘little girl.’ At 375 milliliters, 4 glasses, the equivalent of half a bottle.

Magnum (2 bottles) 1.5 litres
Latin for “great,” this describes a bottle that is twice the standard size and yields 16 glasses.

The names of the six largest Champagne bottles are of Biblical origin:

Jereboam (4 bottles) 3 litres
Jeroboam (actually Jeroboam II), was the King of Israel during the year of Rome's founding (753 BC)

Rehoboam (6 bottles) 4.5 litres
A son of Solomon, Rehoboam (meaning "the clan is enlarged" according to Willard Espy) became king of Judah in 933 BC.

Methuselah (8 bottles) 6 litres
Methuselah was an antediluvian patriarch described in the Old Testament as having lived 969 years and whose name is synonymous with great age. He may well have evolved from a character of earlier Sumerian legend who lived for 65,000 years.

Salmanazar (12 bottles) 9 litres
Shalmaneser (alternatively spelled Salmanazar) was an Assyrian monarch who reigned around 1250 BC.

Balthazar(16 bottles) 12 litres
Balthazar ("King of Treasures") is the traditional name of one of the Three Wise Men, the other two being Melchior ("King of Light") and Caspar ("The White One"). Many scholars nowadays tend to characterize the trio not as kings but rather as Zoroastrian priests, while others speculate that at least one of them was a king -- namely Azes II of Bactria who reigned from 35 BC to 10 AD. Whatever their occupations, legend and German tourist brochures have it that the Three Wise Men -- or at the very least their skulls -- lie buried in a golden shrine at Cologne Cathedral.

Nabuchadnezzar (20 bottles) 15 litres
Nebuchadnezzar, originally nabu-kudurri-usur meaning "Nabu protect the boundary," became King of the Chaldean Empire in 604 BC. He was actually the second Nebuchadnezzar; a less celebrated Nebuchadnezzar I preceded him by 500 years.

Melchizedek (40 bottles) 30 litres
is an enigmatic figure twice mentioned in the the Old Testament. Melchizedek is mentioned as the King of Salem, and priest of God Most High, in the time of the biblical patriarch Abram. He brought out bread and wine, blessed Abram, and received tithes from him, [Genesis 14:18-20]. Reference is made to him in Psalm 110:4 where the victorious ruler is declared to be "priest forever after the order of Melchizedek." This size bottle should yield around 320 glasses.
Big bottles can be difficult to handle with the average full Nebuchadnezzar, for example, weighing in at around 38kg (84 lb) which means that the bottle itself weighs more than the Champagne it contains. The bottle weighs about 23kg (51 lb)

There are occasionally exceptions to these standard bottle types. Sometimes bottles of different sizes and shapes are used for special occasions or for special cuvées. For example, Pol Roger made a 20 fluid ounce/ 60cl. bottle (imperial pint) specially for Sir Winston Churchill, which his manservant brought him each morning at 11 am. Extremely rare is the 18 litre, 24 bottle Solomon (Salomon in French), and even rarer is the gigantic 27 litre, 36 bottle Primat (pronounced "preemah"), which weighs in at 65 kilos!

Big bottles have a novelty value, but because of the difficulty in moving such a large mass for riddling and disgorgement (a full Nebuchadnezzar weighs 38 kilos!), in most houses the secondary fermentation is carried out in magnums. The wine is then decanted into the larger bottles. This inevitably results in a loss of pressure. Some would say that there is a chance of more oxidation as a result of this, and that Champagne from a giant bottle is inferior to that from the magnum it was fermented in.

A notable exception to this practice is the house of Drappier, who are very much the big bottle specialists. They carry out bottle fermentation in even the very largest sized bottles. Imagine riddling and disgorging a Primat by hand! Michel Drappiersays that an empty Primat bottle costs around £400! They have to be specially made, and also pressure tested so as to withstand more than 90lbs. per sq. inch (6 bar).

WINE BOTTLE SHAPES

Each year well over one billion wine bottles are made around the world. An explanation of what you may expect from the shape and color of a wine bottle on your merchant shelves can be helpful.

Bordeaux Style
The most common type bottle used is the Bordeaux bottle. The bottle shape is tall with high shoulders and is straight sided. It is a favourite of almost all wine producing countries. Green glass is used for red wines and clear glass for whites. This bottle shape represents the classic Bordeaux soft reds, and dry or sweet whites.

Burgundy Style
A slope-shoulder bottle hints of a full-bodied red wine characterized by the wines of Burgundy and Italy. These are sturdy, heavy bottles, with a slightly fatter girth than other wine bottles - although you may only notice this if stacking them. This shape is also widely used throughout the New World for Chardonnay and Pinot Noir.

Alsacian
This bottle is long and slender. It has something frivolous, a bottle with a lively radiation. The Alsacian bottle is just as the Mozel bottle made out of green glass. It is used for wines such as Riesling, Gewurtztraminer and Pinot.

Rhine and Mozel
The Rhine (Hock) and Mozel bottle is identical in shape to the Alsacian bottle, slender and fine in form. However, the Mozel bottle is made with green glass and the Rhine bottle from brown glass. Wine from the Rhine ('Hock') spends its life in a bottle similar in shape to the Mosel/Alsace bottle. Once again, however, the style of wine can vary, and a little label knowledge is required.


Champagne
The familiar Champagne bottle is the heavy bottomed, thick-lipped, dark green bottle used for the world-famous beverage. The Champagne bottle shape is the only one that has a compelling scientific justification behind it. It has thicker glass that is able to withstand the higher pressure that is found with Champagne (up to 90 psi).

Fortified Wine Bottle
Fortified wine bottles used for Port and Sherry are sturdy and typically have a bulge in the neck supposedly in order to help capture the sediment, as the wine is decanted. Many of these wines, especially if for drinking young, would be sealed with a cork stopper rather than a long cork.

Rhône
Similar in style to the Burgundy, but not so fat. In addition, some may bear a coat of arms on the neck, particularly Châteauneuf du Pape. The traditional Côtes du Rhône bottle is similar in shape, but with more angular sloping shoulders. New World Shiraz may have a similar bottle, but often this is not the case.

PUNT

The PUNT is also known as a kick-up refers to the dimple at the bottom of a wine bottle. There is no consensus explanation for its purpose. The more commonly cited explanations include:
  • It is an historical remnant from the era when wine bottles were free blown using a blowpipe and pontil. This technique leaves a punt mark on the base of the bottle; by indenting the point where the pontil is attached, this scar would not scratch the table or make the bottle unstable.- a reasonable explanation
  • It had the function of making the bottle less likely to topple over -- a bottle designed with a flat bottom only needs a small imperfection to make it unstable -- the dimple historically allowed for a larger margin of error. Another reasonable explanation
  • It consolidates sediment deposits in a thick ring at the bottom of the bottle, preventing much/most of it from being poured into the glass; unlikely
  • It increases the strength of the bottle, allowing it to hold the high pressure of sparkling wine/champagne. Another reasonable explanation
  • It holds the bottles in place on pegs of a conveyor belt as they go through the filling process in manufacturing plants. Nonsense – the Punt was there long before conveyers
  • It accommodates the pourer's thumb for stability and ease of pouring.This may be how it is used but is not a reasonable explanation for its existence
  • According to legend the punt was used by servants. They often knew more than their master about what was happening in town, and with a thumb up the punt they could show their master whether a guest was reliable or not. This may be how it is used but is not a reasonable explanation for its existence
  • It provides a grip for riddling [see explanation below] a bottle of sparkling wine manually in the traditional champagne production process. - a reasonable explanation
  • It simply takes up some of the volume of the bottle, giving the impression that you're getting more wine for your money than is actually the case. – Just “NO!”
  • Taverns had a steel pin set vertically in the bar. The empty bottle would be thrust bottom-end down onto this pin, puncturing a hole in the top of the punt, guaranteeing the bottle could not be refilled [folklore]. With a Champagne bottle it would require a strong bar, pin and barman – and broken glass has never been recommended around serving areas!
  • The punt acts as a lens, refracting the light to make the colour of the wine more appealing. In an under-lit display cabinet, perhaps – but there weren’t a lot of those around when the bottles were first designed !
  • Prevents the bottle from resonating as easily, decreasing the likelihood of shattering during transportation. Yeah, right ! This doesn’t appear to be a problem with all the bottles that don’t have a punt !
  • Allows bottles to be more easily stacked end to end. -  and turned when stacked – a reasonable explanation
  • An indication of wine quality (the deeper the punt, the better the wine).- -this is just not true.

RIDDLING


Le Remueur: 1889 engraving of the man engaged in the laborious daily task of turning each bottle a fraction [Wikipeda.org]
After aging (a minimum from one and a half to three years), the sediment (lees) must be consolidated for removal. The bottles undergo a process known as riddling (remuage in French). In this stage the bottles are placed on special racks called pupitres. This places the bottles at a 45 degrees with the cork pointed down. Every few days the bottles are given a slight shake and turn and dropped back into the pupitres (eventually the angle is increased). The drop back into the rack causes a slight tap, pushing sediments toward the neck of the bottle. In about 6 to 8 weeks the position of the bottle is pointed straight down with sediment in the neck of the bottle. This manual way of riddling sparkling wine is still used for Prestige Cuvées in Champagne, but has otherwise been largely abandoned because of the high labour costs. Mechanised riddling equipment called gyropalettes are used instead.
