In this case, we can say that the onion is yellow (universal variety with white flesh and yellow, golden tinge of scales), white (white flesh is combined with light, white color of the husk) and red (have purple-red husks and white-purple flesh) .
Each of these types can have different tastes and be bitter, sweet and semi-sweet varieties. As a rule, the “measure” is the universal yellow species, in which bitterness and sweetness are regulated. Although he, depending on the variety, may be more or less bitter.
The characteristic of white onions usually includes the remark that it has a more delicate taste, it does not burn the mucous and has looser petals. Red species can be both sweet (for example, Yalta, grown in certain areas of the Crimea), and with pronounced bitterness.
Taste qualities of a vegetable depend not only on the selected variety, but also on the growing region, peculiarities of care. If you need varieties of onions for storage, then you should pay attention to the "Orion", "Stuttgarter Riesen", "Saturion". These varieties, in addition to good keeping quality, demonstrate high yields and can be bred even by inexperienced gardeners - so unpretentious they are in their care, they are immune to the most common diseases for culture. White onions are not suitable for storage.
When choosing a particular variety, it is important to take into account the climatic conditions of growth. For example, Centurion is characterized by versatility of cultivation and the ability to adapt to any weather conditions, while real red Yalta onions can be grown only between Yalta and Alushta. When grown in all other regions, it will not have that special sweetness.
As a rule, hybrid varieties show less dependence on weather conditions and grow in most climatic zones. These include “Hercules”, “Campillo”.
Finally, for different dishes one or another kind of vegetable may be required - this is the only way to achieve originality and authenticity of the finished dish. So, yellow onions are usually used in dishes undergoing heat treatment. In the process of cooking on the fire, it loses its sharpness and becomes more pleasant to the taste. And for salads it is better to use white or red onions, which give them a piquant shade. They are good in pasta, pizza, sauces.
In stews, casseroles, pickled onion rings, as well as the famous French soup, sweet varieties of white onions show themselves well (for example, Walla Walla, Vidalia).

Regardless of the method of cooking from the onion, you need to remove the top layer, it is enough to remove only the husk and one layer of onions, since it is the first upper layers that contain the greatest number of useful elements. The bulbs need to cut the bottom and the "tail". If necessary, rinse or soak in cold water for a while. This will get rid of unnecessary bitterness.

The shelf life of onions under certain conditions is 12-14 months. If you grow onions at your summer cottage, then after harvesting, you need to free it from clods of soil and dry it for a couple of hours in the sun, and then transfer it to the shed. It is better to start harvesting in the morning so that there is still a whole day left for drying.
Further, the "tails" of the bulbs are cut so that their length is 5-7 cm, are tied in bunches and are suspended for a week in a dry, well-ventilated room. After that, the "tails" again cut to 2-3 cm.
Before storing onions for storage, it is important to review each vegetable to prevent the entry of rotten and damaged onions.

The optimum temperature is + 3 ... +10 degrees, however, the temperature may drop to 0. It is believed that the sharper the onion, the lower the temperature should be stored. However, it is important to remember that a sharp decrease in temperature can lead to crop damage. Some varieties of onions (for example, red) are recommended to gradually harden, each day reducing the temperature by half a degree until the desired storage temperature is reached. Humidity level should not exceed 80%.
For the safety of the crop it is also important to ensure the air permeability of the room. Onions can be stored in the cellar, on the upper shelves of cabinets and mezzanines, heated balconies, in the refrigerator. You can use cardboard boxes, wooden boxes, wicker baskets or use the Soviet way - keep the bow in nylon tights.
