Hydrolysable chestnut tannins can be used for partial phenol substitution in phenolic resin adhesives production [115] and also for direct use as resin.

Their carbohydrate content compares with that of wheat and rice. [43] Chestnuts have twice as much starch as the potato on an as-is basis. [38] They contain about 8% of various sugars, mainly sucrose, glucose, fructose, and in lesser amounts, stachyose and raffinose, which are fermented in the lower gut, producing gas. [11] Pizzi, A.

Cited in Plants For A Future. Chestnuts produce a better crop when subjected to chill temperatures during the dormant period. Frosts and snowfalls are beneficial rather than harmful to the trees. [5] [66] The dormant plant is very cold-hardy in Britain, [71] to the Royal Horticultural Society's H6 hardiness rating, to -20°C. [72] Chestnut is hardy to USDA zone 5, which is −29°C (−20°F) lower in average minimal temperature than London in zone 9. [73] The young growth in spring, even on mature plants, however, is frost-tender; [71] [73] bud-burst is later than most other fruit trees, so late frosts can be damaging to young buds. [66]The taxonomy of the American chestnuts is not completely resolved, particularly between the chinkapins ( C. ozarkensis and C. pumila), which are sometimes considered to be the same species. There is also another chestnut, Castanea alabamensis, which may be its own species.

Chestnut wood is a useful source of natural tannin and was used for tanning leather before the introduction of synthetic tannins. [60] On a 10% moisture basis, the bark contains 6.8% tannin and the wood 13.4%. [108] The bark imparts a dark color to the tannin, and has a higher sugar content, which increases the percentage of soluble non-tans, or impurities, in the extract; so it was not employed in this use. [109] Chestnut tannin is obtained by hot-water extraction of chipped wood. It is an ellagic tannin and its main constituents are identified by castalagin (14.2%) and vescalagin (16.2%). [110] [111]Sacred Chestnut of Istán, 46-foot (14m) circumference, estimated to be between 800 and 1,000 years old. [121] The chestnut weevil ( Curculio elephas) most often damages the fruits. In Hungary, it swarms in chestnut orchards around August 20, particularly strongly around noon and in sunny weather. The eggs are laid into the cupules or around the peduncle joints. The larvae feed on the nuts and leave only nutchips and excrement within. While the chestnuts ripen, the larvae retreat into the ground after having chewed their way out of the nuts. The following July, they turn into pupae.

The larvae of the oak-leaf-mining moth, also called the tischerid moth ( Tischeria ekebladella), digs white, see-through mines in chestnut leaves. It lays its eggs in the leaves between May and June. The larvae cause white spots in the leaves by chewing them from the inside. [85] In some areas, sweet chestnut trees are called "bread trees". [46] [69] When chestnuts are just starting to ripen, the fruits are mostly starch and are firm under finger pressure from the high water content. As the chestnuts ripen, the starch is slowly converted into sugars, and moisture content decreases. Upon pressing the ripe chestnut, a slight "give" can be felt; the hull is not so tense, and space occurs between the flesh of the fruit and it.

Other species commonly mistaken for chestnut trees are the chestnut oak ( Quercus prinus) and the American beech ( Fagus grandifolia), [6] [7] both of which are also in the Fagaceae family.Cruz, Chino L.

Chestnut tannin is one of the pyrogallol class of tannins (also known as hydrolysable tannin). As it tends to give a brownish tone to the leather, it is most often used in combination with quebracho, mimosa, tara, myrabolans, and valonia. [109] It is therefore uncommon to find large pieces of chestnut in building structures, but it has always been highly valued for small outdoor furniture pieces, fencing, cladding ( shingles) for covering buildings, [105] and pit-props, [22] for which durability is an important factor. In Italy, chestnut is also used to make barrels used for aging balsamic vinegar and some alcoholic beverages, such as whisky or lambic beer. [106] Of note, the famous 18th-century "berles" in the French Cévennes are cupboards cut directly from the hollowed trunk. [107] Fuel [ edit ]Tiu, Danilo (6 January 2018).

The fruit is contained in a spiny (very sharp) cupule 5–11 cm in diameter, also called "bur" or " burr". [28] The burrs are often paired or clustered on the branch [23] and contain one to seven nuts according to the different species, varieties, and cultivars. [1] [2] [29] [30] Around the time the fruits reach maturity, the burrs turn yellow-brown and split open in two or four sections. They can remain on the tree longer than they hold the fruit, but more often achieve complete opening and release the fruits only after having fallen on the ground; opening is partly due to soil humidity.
