White onion

The white onion is a spring onion , traditionally harvested before fully ripening. Currently it can be had all season, although they have little storage capacity, spoiling earlier than other varieties.

Yellow onion, one of the most common types of onion

It is what is known as the common onion in a large number of countries. Thanks to its low water content, its storage capacity is quite large, and can be stored for several months even without refrigeration.

The yellow onion is used mainly for cooking, although it can also be eaten fresh. Depending on the point at which it has been collected, its flavor is more or less spicy, although in the warm months it is always milder.

Vidalia onion

The vidalia onion owes its name to the town in the state of Georgia, in the USA. It is grown in soils poor in sulfur, so its flavor is much milder. In fact, it is considered one of the sweetest types of onions to plant. It is distributed throughout the year, but its peak of the season is between April and September, that is, in the warm months.

Its consumption is recommended especially for those who suffer from gas or flatulence, since its low sulfur content causes them to cause them to a much lesser degree than other varieties. In some countries it is sold under the sweet onion label . It is easy to confuse, since its appearance is quite similar to that of the yellow onion, although somewhat flatter.

Calçot

Calçot is a type of tender onion , with a little pronounced bulb, whose popularity has made it a symbol of Catalan gastronomy. It is considered a delicacy in many regions, and goes through a process of development and replanting.

Its production respects the seasonality, being consumed habitually from November, when the cold arrives. Its consumption gives rise to the so-called calçotades , in which people gather to roast the calçots on coals and eat them with their most typical sauces, salvitxada and romesco.

The chive is not an incompletely ripened onion as many believe, but a different species of the Allium family, Allium fistulosum . It is also commonly called scallion or Chinese onion .
