The fruit is a triangle-shaped shell containing 2–3 nuts inside, but many of them do not fill in, especially on solitary trees. Beech nuts are sweet and nutritious, [7] can be eaten raw by wildlife and humans, [26] or can be cooked. [27] They can also be roasted and ground into a coffee substitute. [7] The leaves are edible when cooked. [7]

Moreover, with some phytophthoric diseases, no tannic acid is generated. With the ink disease, the leaves turn yellow and later fall off; the fruits remain small, and the nuts prematurely drop out of the burrs. These dry and remain on the trees throughout winter. In acute cases, root decay makes the trees dry out and wither away. [84]
The fruit is a small, sharply three-angled nut10–15 mm (3 ⁄ 8 – 5 ⁄ 8 in) long, borne singly or in pairs in soft-spined husks 1.5–2.5 cm (5 ⁄ 8 –1 in) long, known as cupules. The husk can have a variety of spine- to scale-like appendages, the character of which is, in addition to leaf shape, one of the primary ways beeches are ...
The female flowers produce beechnuts, small triangular nuts 15–20 mm (5 ⁄ 8 – 3 ⁄ 4 in) long and 7–10 mm (1 ⁄ 4 – 3 ⁄ 8 in) wide at the base; there are two nuts in each cupule, maturing in the autumn 5–6 months after pollination. Flower and seed production is particularly abundant in years following a hot, sunny and dry summer ...
The husk of the acorn in most oaks only forms a cup in which the nut sits. Other members of the family have fully enclosed nuts. Fagaceae is one of the most ecologically important woody plant families in the Northern Hemisphere, as oaks form the backbone of temperate forest in North America, Europe, and Asia, and are one of the most significant ...
[1] [2] The underlying physiological mechanism is that trees transfer water and sap from the roots to the leaves through their vascular cells, but in some trees as autumn begins, the veins carrying the sap slowly close until a layer of cells called the abscission layer completely closes off the vein allowing the tree to rid itself of the leaf.

American oak contributes greater texture and resistance to ageing, but produces a more powerful bouquet. [85] [86] Oak wood chips are used for smoking foods such as fish, meat, and cheese. [87] [88] In Japan, Children's Day is celebrated with Kashiwa-mochi rice cakes, filled with a sweet red bean paste, and wrapped in a kashiwa oak leaf. [89]
