It is therefore not possible to make an exact conversion between these units. Representative figures for the amount of grapes needed for 100 L of wine are 160 kg for white wine, 130 kg for red wine, and 140 kg for a mixture of red and white wine. [1] Thus: [2] for white wine, 100 hl/ha ≈ 16,000 kg/ha (16 t/ha) = 6.5 tons per acre.
The Oechsle scale is a hydrometer scale measuring the density of grape must, [ 1 ] which is an indication of grape ripeness and sugar content used in wine-making. It is named for Ferdinand Oechsle (1774–1852) and it is widely used in the German, Swiss and Luxembourgish wine-making industries. On the Oechsle scale, one degree Oechsle (°Oe ...
Such scales are used to make the most accurate of fine measurements, such as in the needs of empirical chemistry. Avoirdupois (/ ˌævərdəˈpɔɪz, ˌævwɑːrdjuːˈpwɑː /; [1] abbreviated avdp.) [2] is a measurement system of weights that uses pounds and ounces as units. [3][4] It was first commonly used in the 13th century AD and was ...
Conversion of the measurement to cup size is shown in the "Measuring cup size" table. [ 73 ] Note that, in general, countries that employ metric cup sizing (like in § Continental Europe ) have their own system of 2 cm (0.79 in) increments that result in cup sizes which differ from those using inches, since 1 inch (2.5 cm) does not equal 2 ...
Conversion of units is the conversion of the unit of measurement in which a quantity is expressed, typically through a multiplicative conversion factor that changes the unit without changing the quantity. This is also often loosely taken to include replacement of a quantity with a corresponding quantity that describes the same physical property ...
Length. For measuring length, the U.S. customary system uses the inch, foot, yard, and mile, which are the only four customary length measurements in everyday use. From 1893, the foot was legally defined as exactly 1200⁄3937 m (approximately 0.304 8006 m). [13] Since July 1, 1959, the units of length have been defined on the basis of 1 yd = 0 ...
A bread stall, from a Pompeiian wall painting. Most people would have consumed at least 70 percent of their daily calories in the form of cereals and legumes. [1] Grains included several varieties of wheat—emmer, rivet wheat, einkorn, spelt, and common wheat (Triticum aestivum) [2] —as well as the less desirable barley, millet, and oats.
In alcoholic fermentation it is the conversion of sugars to alcohol by yeast while in malolactic conversion it is the conversion of malic acid to lactic by bacteria. Feuillette A French wine barrel with the capacity to hold 30 US gallons/25 imperial gallons (114 liters) in Burgundy and 35 US gallons/29 imperial gallons (132 liters) in Chablis .
