Birch syrup is syrup made from birch sap, and produced in much the same way as maple syrup. However, it is seldom used for pancake or waffle syrup as it has a much stronger flavor profile, more often it is used as an ingredient paired with pork or salmon dishes in sauces, glazes, and dressings, and as a flavoring in ice cream, beer, wine, and soft drinks.
It is condensed from the sap, which has about 0.5–2% sugar content, depending on the species of birch, location, weather, and season. The finished syrup is 66% sugar or more to be classified as a syrup. Birch sap sugar is about 42–54% fructose and 45% glucose, with a small amount of sucrose and trace amounts of galactose.
The main sugar in maple syrup is the more complex sucrose, and the chemical contents of maple syrup are also different, leading to a flavor difference. [1]
The flavor of birch syrup has a distinctive and mineral-rich, caramel-like taste described to be similar to molasses, balsamic condiment, or some types of soy.[ clarification needed ] Different types of birch will produce slightly different flavour profiles; some more copper, others with hints of wildflower honey. While birch syrup has the same sugar content of maple, it is darker, stronger, and more complex.
Making birch syrup is more difficult than making maple syrup, requiring about 100–150 liters of sap to produce one liter of syrup—more than twice the sap needed for maple syrup. [2]
The tapping window for birch is generally shorter than for maple, primarily because birches live in more northerly climates. It also happens later in the year than maple tapping. The trees are tapped and their sap collected in the spring (generally mid- to late April, about two to three weeks before the leaves appear on the trees).
The common belief is that while birches have a lower trunk and root pressure than maples, pipeline or tubing method of sap collection used in large maple sugaring operations is not as useful in birch sap collection. However Rocky Lake Birchworks in The Pas, Manitoba is successfully using the tubing method along with a vacuum system for collection of birch sap.
The sap is reduced in the same way as maple sap, using reverse osmosis machines and evaporators in commercial production. While maple sap may be boiled down without the use of reverse osmosis, birch syrup is difficult to produce this way. Birch sap is more temperature sensitive than maple sap because fructose, the primary sugar in birch sap, burns at a lower temperature than sucrose, the primary sugar in maple sap. This means that boiling birch sap to produce syrup can much more easily result in a scorched taste.
Most birch syrup is produced in Russia, Alaska and Canada from paper birch or Alaska birch sap (Betula papyrifera var. humilis and B. neoalaskana). These trees are found primarily in interior and south central Alaska. The Kenai birch (Betula papyrifera var. kenaica), which is also used, grows most abundantly on the Kenai Peninsula, but is also found in the south central part of the state and hybridizes with B. humilis. The southeast Alaska variety is the Western paper birch (Betula papyrifera var. commutata), and has a lower sugar content. One litre of syrup from these trees requires evaporation of approximately 130–150 litres of sap. [3]
Total production of birch syrup in Alaska is approximately 3,800 liters (1,000 U.S. gallons) per year, with smaller quantities made in other U.S. states and Canada (also from paper birch), Russia, Belarus, Ukraine, and Scandinavia (from other species of birch). Because of the higher sap-to-syrup ratio and difficulties in production, birch syrup is more expensive than maple syrup, up to five times the price.
Maple syrup is a syrup made from the sap of maple trees. In cold climates, these trees store starch in their trunks and roots before winter; the starch is then converted to sugar that rises in the sap in late winter and early spring. Maple trees are tapped by drilling holes into their trunks and collecting the sap, which is processed by heating to evaporate much of the water, leaving the concentrated syrup.
Corn syrup is a food syrup which is made from the starch of corn/maize and contains varying amounts of sugars: glucose, maltose and higher oligosaccharides, depending on the grade. Corn syrup is used in foods to soften texture, add volume, prevent crystallization of sugar, and enhance flavor. It can be processed into high-fructose corn syrup (HFCS) by using the enzyme D-xylose isomerase to convert a large proportion of its glucose into sweeter fructose.
Maple sugar is a traditional sweetener in Canada and the northeastern United States, prepared from the sap of the maple tree.
Betula pubescens, commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing farther north than any other broadleaf tree. It is closely related to, and often confused with, the silver birch, but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch.
Inverted sugar syrup, also called invert syrup, invert sugar, simple syrup, sugar syrup, sugar water, bar syrup, syrup USP, or sucrose inversion, is a syrup mixture of the monosaccharides glucose and fructose, that is made by hydrolytic saccharification of the disaccharide sucrose. This mixture's optical rotation is opposite to that of the original sugar, which is why it is called an invert sugar.
Golden syrup or light treacle is a thick, amber-coloured form of inverted sugar syrup made by the process of refining sugar cane or sugar beet juice into sugar. It is used in a variety of baking recipes and desserts. It has an appearance and consistency similar to honey, and is often used as a substitute where honey is unavailable.
Betula papyrifera is a short-lived species of birch native to northern North America. Paper birch is named after the tree's thin white bark, which often peels in paper-like layers from the trunk. Paper birch is often one of the first species to colonize a burned area within the northern latitudes, and is an important species for moose browsing. Primary commercial uses for paper birch wood are as boltwood and sawlogs, while secondary products include firewood and pulpwood. It is the provincial tree of Saskatchewan and the state tree of New Hampshire.
Betula alleghaniensis, the yellow birch, golden birch, or swamp birch, is a large tree and an important lumber species of birch native to northeastern North America. Its vernacular names refer to the golden color of the tree's bark. In the past its scientific name was Betula lutea, the yellow birch.
Birch sap,birch water or birch juice is the sap directly tapped from birch trees, Betula pubescens, Betula pendula, Betula lenta, Betula papyrifera, and Betula fontinalis.
Agave syrup, also known as maguey syrup or agave nectar, is a sweetener commercially produced from several species of agave, including Agave tequilana and Agave salmiana. Blue-agave syrup contains 56% fructose as a sugar providing sweetening properties.
Sugar bush refers to a forest stand of maple trees which is utilized for maple syrup. This was originally an Indigenous camp set up for several weeks each spring, beginning when the ice began to melt and ending when the tree buds began to open. At a traditional sugarbush, all the trees were hand tapped and the sap was boiled over wood fires. The Anishinaabe (Ojibwe) peoples have been doing sugarbush for generations and consider the process both a part of food and of medicine.
Coconut sugar is a palm sugar produced from the sap of the flower bud stem of the coconut palm.
Maple liqueur refers to various alcoholic products made from maple syrup, primarily in the Northeast United States and Canada. It is most commonly made by mixing Canadian rye whiskey and Canadian maple syrup. Maple liqueur is considered an important cultural beverage in certain Canadian festivals.
Crown Maple Syrup is a certified organic maple syrup company based in Dover Plains, NY. The company was established by Robb Turner in 2010. The sap used to produce maple syrup comes from tapped maple trees in areas ranging from the Hudson Valley to Western Vermont. The syrup is processed and bottled at Madava Farms on an 800-acre site. The farm is considered to be the largest maple syrup production facility in North America.
Nira or lahang is a sweet liquid obtained from the stems of plants such as sugarcane, sugar beet, sorghum, maple, or the sap of the flower stalks (spathe) of the palm family such as arenga palm, coconut, date palm, nipa palm, sago palm, tal and others.
