Birch sap is a clear liquid that flows out of cut or broken birch trunks and branches under the action of root pressure. Sap flow of birch sap begins in the spring with the first thaws and continues until the buds open.

The exact period of release of birch sap is difficult to establish, because it depends on weather conditions. For example, if during the March thaw the juice has already begun to flow and frost suddenly hits here, then it may stop flowing for some time. However, as a rule, the juice begins to run around mid-March, when the snow melts and the buds swell. To determine the beginning of sap flow, it is enough to go out into the forest and make an injection with a thin awl on a birch as thick as your arm. If the juice has gone, then a drop of juice will immediately come out at the puncture point, which means you can start collecting and harvesting it. Collecting juice is stopped in the second half of April, when the leaves are already blooming.

The most intensive sap flow through the tree occurs in the light half of the day, so it is better to start collecting in the morning, at night the juice “falls asleep”. The best time to collect the juice will be between 10.00 and 18.00, when it flows most strongly. The number of holes that are recommended to be made depends on the diameter of the tree, if 20-25 cm - then only one, with a volume of 25-35 cm - two, with 35-40 - three, and if the diameter is more than 40 cm - it is quite possible to make four holes.

The collection of birch sap should be started in the most sun-warmed places, where the birch wakes up even if there is still snow around. As the forest warms up, one should move deeper into the thicket, to where the forest wakes up later than on the southern edge. Usually, 2-3 liters of juice per day are obtained from a birch. A large tree can produce about 7 liters of juice per day, and sometimes more. It is preferable to collect the sap where the felling is planned, and it is not recommended to take it from young trees.

Due to the fact that birch roots go far into the ground, it does not absorb poisons from the surface layer of the soil. Therefore, all places where birch grows are equally good for collecting birch sap, but it is still better to collect sap only in ecologically clean forests, because the tree itself is able to absorb harmful substances and exhaust gases.

The choice of dishes for collecting and storing birch sap must be approached selectively. In the old days, birch sap was collected in special boxes made of birch bark, it was believed that in them it retains its properties better. But it is quite possible to collect juice in ordinary glass jars or even in plastic bottles, but remember that chemistry is able to give the juice its specific flavor, and sometimes it dissolves in it itself.

Juice is usually obtained by cutting, cutting or drilling the bark of a tree, the diameter of which is not less than 20 cm, with a well-developed crown. It is better to make a slot or a hole in the trunk on the south side of the tree, where the sap flow is more active, at a distance of 40-50 cm from the ground, downward, your movement should be from the bottom up, the depth of the hole is 2-3 cm to penetrate under the dead bark, and if birch is very thick, then even deeper.

An aluminum, plastic groove, birch bark tray or other semicircular device is inserted into the slot, through which the juice flows into the container. Sometimes the juice is extracted by cutting off small branches and attaching a plastic bag to the place of the cut. No need to strive to drain all the juice from one tree, it compensates for some of it, but if you bleed the tree completely, it can dry out. It is better to take a liter of juice per day from 5-10 trees than to take 5 liters from one, dooming it to death.

After the collection of birch sap is over, it is necessary to take care of the tree itself and tightly close the holes made with wax, cork or moss so that bacteria do not get into the trunk, which can seriously threaten the life of the tree. After birch trees are cut, sap collection can be organized from stumps.

If you do not want to drink the juice right away, but want to keep it longer, pour it into a glass jar and refrigerate. So the drink will be less oxidized, that is, spoil. However, it is better not to store the juice for longer than 2-3 days, otherwise it will ferment and turn from healing nectar into poison. But if you preserve the juice, then it will stand for a few more months.

Several recipes for preserving birch sap for long-term storage.

Fresh birch sap is fermented in glass containers of any volume. After washing with hot, preferably boiled, water, they are filled with fresh juice. For every half liter, add an incomplete teaspoon of ordinary or glucose sugar, 2-3 raisins washed in cold boiled water, and if you like, a little lemon zest. The container is closed with a cork or lid and secured with wire or bandages.

The pressure of carbon dioxide during fermentation is quite high, and so that the glass does not burst, putting more than the specified amount of sugar is not recommended. After a few days, you will have a pleasant-tasting, sour, highly carbonated drink. To preserve the juice, heat it in an enamel bowl to a temperature of 80 degrees. Pour into glass bottles and jars. Fill almost to the top and cork with lids, and bottles with corks, followed by grinding. Then soak for 15 - 20 minutes in water of 85 degrees for pasteurization.

Preparation of kvass from birch sap.

To preserve birch sap, kvass is made from it. Heat up to 35 degrees, add 15-20 g of yeast and 3 raisins per 1 liter, you can add lemon zest to taste. After that, the jar or bottle is tightly closed and left for 1-2 weeks. Kvass can be prepared in a different way. To 10 liters of birch sap add the juice of 4 lemons, 50 g of yeast, 30 g of honey or sugar, raisins at the rate of 2-3 pieces per bottle. Pour into bottles and keep 1-2 weeks in a dark cool place. Kvass can be ready already in 5 days, but the fact that it stays longer will not spoil the drink, it can be stored for the whole summer.

Another kvass recipe. A bag with burnt crusts of rye bread is lowered on a rope into a barrel with birch sap. After two days, yeast will pass from the crusts into the juice and fermentation will begin. Then a bucket of oak bark is poured into the barrel, as a preservative and tanning agent, and for aroma - cherries (berries or leaves) and dill stalks. After two weeks, kvass is ready, it can be stored all winter.

Other methods of conservation and preservation of birch sap.

Our ancestors drank birch sap fermented in barrels without added sugar - it was a traditional low-alcohol drink at Russian feasts. Birch juice itself is a pleasant, refreshing and strengthening drink for the body, but you can add juice of chokeberry, lingonberry, blueberry to it or insist on various herbs - thyme, chamomile, cumin, linden flowers, rose hips, in a jar covered with gauze for about 2 weeks .

You can add to it infusions of St. John's wort, mint, lemon balm, pine needles, cherry juice, apples, currants. Birch sap can be evaporated to a syrup containing 60% sugar. This syrup has a lemon-white color and the density of honey.

Drink in Belarusian - pour birch sap into a large bottle and put in a dark, cool place for 2-3 days. Then barley malt or toasted crushed crackers are added to it. For 5 liters of birch sap - 30 gr. barley malt or breadcrumbs. Balm is also prepared from birch sap. A bucket of juice needs 3 kg of sugar, 2 liters of wine and 4 finely chopped lemons. All this must be put to ferment for two months in the cellar, and then bottled and kept for another three weeks.

In addition, you should not use juice that was collected in close proximity to highways, or with an expired shelf life.

Product Collection Rules

The optimal period when you can collect birch sap is the beginning of March. It should be borne in mind that one tree can produce about 3 liters of juice, in rare cases - about 7 liters.

First you need to determine if there is sap in a particular tree. To do this, it is enough to make a small hole in the bark using an awl. If after these steps you see a drop that stands out, you can safely start collecting nectar.

You need to choose only mature trees, the crown of which is quite well developed. It is desirable to drill a hole from the south side at a distance of 50 cm from the ground. The drill should be pointing down. After that, a groove must be inserted into the hole. It is through it that the juice will drain into the left container. To maintain the life of the plant, it is recommended to collect no more than 1 liter of fluid per day.

How to store?

Freshly harvested juice can be kept in the refrigerator for up to three days. It is also preserved. Can be obtained by drinking canned birch sap, benefits and harms.

Another way to store juice is freezing. All nutrients will be preserved.

Surely you have only tried this drink, but you have never collected it yourself. To correct this situation, we decided to tell you in detail about how to properly extract birch sap.

General information about the drink

Before telling you about how birch sap is collected, I would like to tell you what this drink is.

Birch sap is a liquid that flows from broken and cut birch branches and trunks, which occurs as a result of root pressure.

Surely everyone knows that birch (the second name of the drink we are considering) is a very valuable and nutritious product. This is due to the fact that it has a beneficial effect on the entire human body.

The composition of the drink and useful properties

In spring, sweet birch sap is extracted due to the fact that it is very rich in vitamins and minerals. Experts say that this drink includes the following substances: various sugars, phosphorus, potassium, zirconium, sodium, nickel, calcium, barium, magnesium, strontium, aluminum, copper, manganese, titanium, iron and silicon. Scientists also found traces of nitrogen in it.

Drinking the drink helps cleanse the blood, break down stones in the kidneys and bladder, and increase metabolism. It also removes toxins and other harmful substances from the body.

Among other things, it is useful to drink birch sap for liver diseases, stomach ulcers, gallbladder pathologies, low acidity, rheumatism, scurvy, sciatica, arthritis, headaches, tuberculosis, and even sexually transmitted diseases.

When to collect birch sap?

Sap production from birch begins in early spring, with the first thaws. This period continues until the buds open. However, it should be noted that the exact time of juice release is quite difficult to establish, since it completely depends on weather conditions. Although most collectors claim that "birch tears" begin to run as early as mid-March.

To independently determine the beginning of the sap flow period, you just need to come to the forest and prick a birch with a thin awl. If after this action droplets of life-giving moisture appear from the hole, then you can safely proceed to its collection and further harvesting.

In our country, maple sap is very rarely extracted. And its volume is quite difficult to compare with birch. This is due to the fact that sugar maple grows only in North America, while other species are not fast growing enough to provide a large amount of life-giving drink.

Maple sap is widely used in the northeastern United States as well as in southeastern Canada. As a rule, it is used to obtain a sweet syrup, which is often consumed with pancakes and added to various confectionery products.

Summing up

In this article, we answered in detail the question of how to make birch sap tasty and store it for a long time, and also discussed how it should be extracted without harming trees. Thanks to these tips, you will definitely get a very tasty and healthy drink that will quench your thirst well and saturate the body with minerals and organic acids. Do not forget to only "treat" the slender beauty and treat the wound so that the tree does not die.

Birch sap, or birch tree, as it is popularly called, has been famous for its healing properties since ancient times - it is an environmentally friendly, tasty, healing, refreshing soft drink. The healing secret is that in the spring the birch splashes into the leaves all the vitality that it accumulated during the winter.

When is birch sap harvested?

Birch sap is collected until the sticky leaves have blossomed (about a month before the appearance of leaves and flowering, during the period of snow melting), sap flow begins at birch trees, called “birch weeping”. Within 15-20 days, the birch gives us its sweet juice.

How to extract birch sap?

Option 1: Hole in the barrel

If you delve into the library or the Internet, looking for the rules for collecting birch sap, then general recommendations will relate to something like the following. The sap should be collected (specialists call the targeted extraction of birch sap tapping) from mature trees with a well-developed crown and a trunk of at least 30 cm in diameter. At the same time, a small hole (channels) with a diameter of up to 2 cm is drilled in the bark, depending on the diameter of the tree, from one to four holes are made on it, and a tube or tin tongue is removed from it, through which birch sap enters a dish attached to a wire or rope.

Important! At the end of the collection of birch sap, the wound is closed with a wooden cork and covered with garden pitch, wax, clay or plasticine. This is necessary in order to prevent pathogens from entering through the notch, which can cause the death of the tree.

That's just the method of collecting birch sap, which is described everywhere, we almost never used. Firstly, it is quite problematic to make the juice flow only through a tube or a tin chute, often most of it flows down the trunk. Secondly, it is not always possible to attach a bottle or jar in such a way that the drops get inside, and if this is possible, then often, when a little juice is collected in the dishes, it shifts under its weight, and the birch sap no longer gets into the neck. Thirdly, you have to make a triangular tongue of birch bark under the hole, thanks to which you can avoid the loss of juice, and traces of these actions remain for a long time, if not forever, disfiguring slender white-trunked birch trees.

Moreover, if you follow the instructions and drill a hole no larger than 2 cm, then in a couple of days the birch sap will flow much more slowly than at the beginning of the damage. And there are two ways out: either increase the hole in diameter, or make a new one. Both of them seemed undesirable to us, so this method was not popular with us. Sometimes I had to meet in the birch forest belts bottles suspended on the trunk, and above them there were several old and fresh holes or, even worse, deep notches with an axe. Unfortunately, this is exactly what the recommendations in the literature look like in practice.

Option 2: Collecting birch sap from a branch

Having rejected the most inconvenient, destructive and, in our opinion, not aesthetic method, we collected birch sap in a different way. They chose a suitable branch, about a finger thick or a little more, but not extending directly from the trunk at an upward angle, but from a thicker branch or almost horizontally. Then they made an oblique cut and pushed a branch into the neck of a one and a half liter or liter bottle, depending on the intensity of sap flow. Fastening the bottle to a branch with wire was not a big pile. Sometimes suitable branches were located at a great distance from the ground, and we had to climb a tree. This made the birch sap even sweeter. However, perhaps this is due to the fact that he went a long way along the trunk and absorbed more glucose and fructose - sugars that determine the sweet taste of a healing drink.

It was also an inviolable rule that we put one bottle or, at most, two on one tree. This ensured both the stability of sap flow throughout the entire period and the limitation of injuries of some of the most “sweet” trees. The latter most often stood separately on some hillock well warmed by the sun. In some places there was still snow, and the birch trees were just beginning to move away from their winter sleep, and here the birch sap was already running in full. We tried not to touch young birch trees, but preferred mature mature trees.

It is better not to collect juice near towns and villages. Do not once again endanger the trees already exhausted by the attention of people. In addition, the sap flow here was always late, rather sluggish and short-lived. And the sap of a tree growing near a busy highway or in an industrial zone of the city, in general, instead of benefit, will only bring harm.

And yet, the amount of birch sap collection is influenced by a number of factors: latitude, type of forest, weather in summer and winter before the tapping and during the tapping period, the hours of the day, the fullness of the forest stand, the degree of tree dominance.

The benefits of birch sap

For medicinal purposes, two types of birch are more often used - drooping and sprawling. Their buds, leaves, juice, ash (activated carbon), tar obtained by dry distillation of wood, xylitol (sugar substitute for diabetics, obtained from waste wood) - all this is widely used in medicine. Birch sap contains 0.5 - 2% sugar, it contains enzymes, organic acids, tannins, calcium, potassium, iron salts, plant hormones, glucose and substances with high antimicrobial activity (phytoncides).

Every year a person should consume at least 6 liters of birch sap. This healing drink destroys urinary stones, is effective in the treatment of stomach and liver ulcers, headaches, bronchitis, coughs, helps with rheumatism, radiculitis, arthritis. In addition, birch sap cleanses the blood, has a regenerating effect, stimulates metabolism, and is also an excellent dietary and refreshing drink. The systematic intake of birch sap has a general strengthening and tonic effect. Doctors say that if you drink at least a glass of juice a day, drowsiness, tiredness, and irritability will disappear. In general, drinking birch sap in its pure form is a pleasure. It is a pleasant, refreshing and strengthening drink.

How to prepare birch sap for good?

125 g of sugar and 5 g of citric acid are added to 1 liter of birch sap. Then filtered, poured into jars, pasteurized and twisted with lids. It is useful to mix birch sap with other juices from fresh fruits and vegetables, as well as to infuse it on mint leaves, lemon balm, thyme, St. John's wort, lime blossom, rose hips, lingonberries.

birch kvass

A bag with burnt crusts of rye bread or crackers is lowered on a rope into an oak barrel with birch sap. After two days, fermentation will begin. Then oak bark, berries or cherry leaves, as well as dill stalks are poured into the barrel. After two weeks, kvass is ready.

There is another recipe. Birch sap is heated to 35 ° C, yeast is added to it at the rate of 15-20 g per 1 liter. The leaven is placed for 3-4 days in a cold place, then poured into containers and preserved.

birch syrup

In addition to kvass, fresh birch sap (sweet and slightly sour in taste) can be used to make a tasty and healthy syrup (it can be added to tea or mixed with water). After evaporation, the concentration of sugar in it reaches 60-70%. This syrup has a lemon-white color and the density of honey. It has been proven that sweet syrup made from birch sap not only prevents dental caries, but even stops its development.
