Grapes: what's in them
Ingredients of the grape: A lot of fructose
Grapes are mainly made up of water. They have a relatively high fructose content. They also contain fruit acids (especially tartaric and malic acid).
Vitamin B6 and folic acid are also found in grapes. The body needs vitamin B6 for protein metabolism, among other things, and folic acid for blood formation, among other things. Grapes also contain the phytochemicals ellagic acid. The antioxidant plant substance resveratrol is found in the skin of the grapes.
Origin: One of the oldest cultivated plants
A distinction is made between grapes and table grapes. Table grapes are the berries that are colloquially known as grapes and that we eat as fruit or in dried form as raisins. Wine is made from grapes. The grapevine is one of the oldest cultivated plants of man. The Egyptians were already growing climbing plants 5000 years ago and processing the grapes into wine. The Romans also valued grapes. They spread the berries throughout the Mediterranean and Northern Europe.
Today wine and table grapes are an economically very important good. Their production ranks second among all types of fruit in the world. 80 percent of the grapes are processed into wine, ten percent are sold as table grapes, the remaining ten percent are offered dried as raisins.
Botany: Around 16,000 grape varieties
First of all: from a botanical point of view, grapes belong to berries. Table grapes and grapes are the fruits of the grapevine, a deciduous climbing plant. The climbing shrub that forms angle tendrils is cultivated on scaffolding systems. The flowers of the plant from which the berries grow are clustered in panicles. The berries are round to oval and green, yellowish, red or blue to black-blue. There are seedless varieties and those with seeds. The kernels are in the two to four compartments of the berry, embedded in the soft, juicy flesh.
A vine carries up to 50 grapes per season and can live up to 60 years. The variety of grape types is huge: there are around 16,000 grape varieties. Mention should be made of the noble muscat grapes, which are white or blue and taste like nutmeg. Grapevines grow in all temperate, partly subtropical regions of the world. Table grapes need a particularly warm and mild climate so that they can develop their sweet and aromatic taste.
Grape season: a permanent guest on the fruit shelf
You can always find grapes on the fruit shelf. The countries of the northern and southern hemisphere alternate in production. Local berries that come from the Mediterranean region are in high season from late August to November.
Storage: grapes do not ripen
Table grapes do not ripen. You should therefore make sure that you only buy fully ripe, undamaged berries. Their scent film, the waxy layer on the berry skin, should also still be present. You should consume grapes quickly, they only last a few days. They stay fresh a little longer in the refrigerator.
Tips for preparation: Fresh, dried or as a juice
Table grapes are suitable as a topping for cakes, you can also cook jelly or jam from them. The berries are often served with cheese platters. When dried, they are very popular as raisins. Grape juice and grape seed oil pressed from the seeds of the berries are made from grapes.
