Why and from where? Do you know why the bottom of a wine bottle is necessarily concave.

The shape of the wine bottle is not a random choice of the manufacturer. Wine containers differ in the color and thickness of the glass, the height and shape of the shoulders, the length of the neck, and the flat or concave bottom. This recess, called a punt, is not on all bottles, which gives rise to conjectures that are far from the truth. The answer to the question "Why do we need a recess at the bottom of a bottle of wine?" lies exclusively in the practical plane.

Which bottles have notches

There are 12 basic types of wine bottles, but the presence or absence of a punt has nothing to do with the quality of the content.

• Bottles "Bordeaux", "Burgundy", "Rhone" have such a recess. On thick-walled glass champagne containers, this recess is especially large.
• Dry, semi-dry, dessert wines are poured into elegant Moselle, Alsace and Rhine bottles. The bottom of these bottles is flat.
• Flattened bocksbeutel also have a bottom without a recess.
• The squat vin Jaune is filled with only a unique yellow wine. They don't have a punch.
• The bottom of rounded chianti straw-wrapped bottles can be flat or concave.

Neither the price nor the origin of the drink makes it clear why there is a recess in the bottom of a bottle of wine.

The purpose of the punt

Making wine bottles with a recess began in France, over time, this practice was recognized as appropriate and spread throughout the world. Since the glassblowers worked by hand, they had no way to make the bottom of the bottle flat - the edge of the molten glass was filled into the recess.

In fact, punt solves several problems.

• Wine is easier to transport

When the wine trade became large-scale, we had to invent ways to safely deliver it. By land, the cargo was moved on wagons, and the losses along the way were too great. To fix the neck of one bottle, they put it in the punt of the next one, the wine was put in straw, and it traveled safely.

• Sediment does not mix with wine

Wines in the process of long aging only get better over the years, but at the same time, a sediment is formed - tartar. They store the bottles lying down, but immediately before drinking, they put the drink on the table and allow it to stand. The sediment falls down and remains in the depression formed by the punt. When wine is poured into glasses, the cream of tartar lingers on the bottom of the bottle.

• Champagne does not break out of the bottle

Sparkling wine bottles are made of thick glass, but still the slightest unevenness on the glass leads to an explosion, for which the depressions at the bottom of the wine bottle are made especially large. Thanks to this, the pressure inside the container is distributed more evenly, and splashes of champagne appear at the right time.

We see or even use these things on a daily basis, but sometimes we don’t pay attention to the obvious details or simply don’t know what they are for.

Why do we need an arrow on the fuel gauge

This arrow was invented by automakers to determine which side the gas tank cap is on without leaving the car. It is very convenient if you just bought a car or rented it from a friend. But not all cars have it.

Are shoes on wires really needed for something?

What are rivets on pockets for?

Initially, jeans were produced as durable work clothes for miners and gold diggers. But one problem was soon discovered: under the weight of nuggets and tools, the pockets could not stand it and were torn at the seams. In order to prevent this, rivets were invented.

Why is this part in the stapler

The stapler in "normal" mode staples documents inward. If you turn the silver platform 180°, then the staples will begin to bend outward. This is designed to temporarily hold sheets together so that the staple can be easily removed without damaging the paper and fingers.

Why a hole and cloves at the end of a tape measure

The hole is designed so that you can hook the tape on a screw or nail and measure the distance.

And the cloves will help you make a mark during measurements, if you suddenly don’t have a pen or pencil at hand.

Why do you need a hole in the bottom of the lock

As a rule, padlocks are used outdoors, and water flows out through this hole, which enters the lock in rainy weather, otherwise the mechanism inside would rust. Also, it is convenient to lubricate the lock through it.

How to know if water has entered your phone

Many batteries have special moisture indicators - a small square or circle that changes color from light to red when wet.

On iPhones starting with iPhone 5, it is located in the SIM card slot. To better see the liquid contact indicator, you can use an illuminated magnifying glass or change the angle of illumination of the device until the indicator is clearly visible.

Why are there ridges on the F and J keys

They are needed for ease of typing: with a blind ten-finger typing method, these keys are basic, index fingers are located on them.

Sometimes in newspapers and magazines (as well as on some websites) you can find a very funny statement that, they say, there should be an indentation in the bottom of a bottle of any decent wine. “The larger the recess, the better the wine,” some people shout. “And in a bottle without a recess, there can only be swill,” others echo. Actually, this is not true.

Let's try to figure out why they began to produce bottles with a recess in the bottom. There are several reasons. First: before, when there was no special equipment, it was generally very difficult to make a bottle with a flat bottom, because the plane had to be even, otherwise the bottle would not be able to stand normally. It was necessary to “fill” the edge of the source material (“glass” mass) into the bottle when blowing. This, of course, took root and became a kind of tradition. So, to a large extent, the recess in the bottom of the bottle (it is called, by the way, punt) is a tribute to traditions.

However, there is also reason number two. When the wine is aged for a long time, a precipitate forms. If there is a bulge in the bottom, then it gathers just in the recesses around it and lingers there when the wine is poured into glasses. So if there is no bulge in a bottle of wine from, say, 2001, then this is really quite a weighty reason to be wary. Especially if we are talking about a little-known manufacturer, and the price is clearly low.

The third reason: you can hold the bottle by the recess with your thumb when pouring wine into glasses. This is what some sommeliers do. There are other reasons as well. In particular, earlier the recess was necessary due to the fact that the bottles were not very strong, and such a bulge inside played the role of an additional stiffener. For sparkling wines, this was (and remains!) Especially relevant, since in a bottle of champagne, for example, the pressure is very high.

As it is easy to understand for any person who has entered a wine store, the shape and size of the recess in the bottom of the bottle vary greatly - also because, by and large, they are unprincipled. As a rule, in bottles with sparkling wines, the recess is larger. In bottles of red wine, it is usually present, but the sizes vary widely. And in bottles of white punt may be completely absent.

Thus, when choosing a wine, one should not attach great importance to the presence of a punt and its size. If the wine is young, then the deepening cannot serve as an indication of its quality. In particular, good young wines (especially whites, sometimes rosés) are often bottled without a punt (examples are Torres Vina Esmeralda, many Australian wines). And in a bottle with a recess in the bottom there can be a very dubious drink (in particular, I met bottles of wine for 120 rubles with a very large punt).

Folks, look at the picture. It's Californian brandy. There is a notch on the bottom of the bottle. Just as a distinctive feature of the bottle shape or some kind of technological sense?

I found in Google the truth for chatter, xs, it can also be used for moonshine to collect all sorts of rubbish.
The recess is needed to collect sediment - tartar that appears in any wine during the aging process. In the hollow of a bottle with a notch, it concentrates on a minimal area, forming rather large pieces that can be left in the bottle without mixing with the rest of the wine when pouring into a glass.

Any notches at the bottom of bottles, glasses, kurzhek, etc. often serve for technological purposes. Namely, for setting a dead point when printing on dishes.
1. When printing labels, position the sticker on the object in this way.
2. When printing directly on the dishes, this is how colors are matched. Because there is a dead point, then subsequent colors will match the first.

With regards to this bottle, x.z.

By the way, what is this hole for?

By the way, what is this hole for? Usually for printing. Glass can be printed with decal or direct printing. Such holes are for direct printing, when they print directly on the object, bypassing the intermediate medium.
The printing plate itself is flat and the round object must rotate under the printing plate for the length of its development. Technological holes in the bottom of the object serve to synchronize the movement of the object with the printing element of the machine (Usually a squeegee). The printing element of the machine moves from the top of the printing plate, the object to be sealed (glass, bottle) moves synchronously from the bottom of the printing plate.

Z.s. True, there is a certain standard for such holes, so that objects fit the maximum number of machines. And what is in the photo is a little like this standard. However, I had to see different ones.

This is a bottle of HUGO BOSS toilet water (in the common people #6). Only a small vertical inscription of two words is printed there. At the bottom of other bubbles (5 more pieces of various shapes and brands have just been examined), nothing of the kind was found, although there are also more complex inscriptions there. H.z. perhaps this way of basing on a plane is applicable only to round bottles? The rest, after all, can be oriented in simpler ways ...

Container for perfume is a separate song. As a rule, various glass matting technologies are used there, and they are based either on immersing an object in a matting medium or firing in special chambers and media. There are technologies when a certain iridescent film is removed from the surface of the water directly with a bubble and burned in the chamber. A dead center is not always needed there, even for cylindrical objects.
