The interaction of heat and carbohydrate is complex. Long-chain sugars such as starch tend to break down into simpler sugars when cooked, while simple sugars can form syrups. If sugars are heated so that all water of crystallisation is driven off, then caramelization starts, with the sugar undergoing thermal decomposition with the formation of carbon, and other breakdown products producing caramel. Similarly, the heating of sugars and proteins elicits the Maillard reaction, a basic flavor-enhancing technique.

This is principally because the confirmed presence of beeswax or certain types of pollen ... is only indicative of the presence of honey (which could have been used for sweetening some other drink) – not necessarily of the production of mead.
Vintage wines are generally bottled in a single batch so that each bottle will have a similar taste. Climate's impact on the character of a wine can be significant enough to cause different vintages from the same vineyard to vary dramatically in flavor and quality. Thus, vintage wines are produced to be individually characteristic of the particular vintage and to serve as the flagship wines of the producer. Superior vintages from reputable producers and regions will often command much higher prices than their average ones. Some vintage wines (e.g. Brunello), are only made in better-than-average years.
A rosé wine incorporates some of the color from the grape skins, but not enough to qualify it as a red wine. It may be the oldest known type of wine, as it is the most straightforward to make with the skin contact method. The pink color can range from a pale orange to a vivid near-purple, depending on the varietals used and wine-making techniques. There are three primary ways to produce rosé wine: skin contact (allowing dark grape skins to stain the wort), saignée (removing juice from the must early in fermentation and continuing fermentation of the juice separately), and blending (uncommon and discouraged in most wine growing regions). Rosé wines can be made still, semi-sparkling, or sparkling, with a wide range of sweetness levels from dry Provençal rosé to sweet White Zinfandels and blushes. Rosé wines are made from a wide variety of grapes all over the world.
The earliest archaeological and archaeobotanical evidence for grape wine and viniculture, dating to 6000–5800 BC was found on the territory of modern Georgia. Both archaeological and genetic evidence suggest that the earliest production of wine elsewhere was relatively later, likely having taken place in the Southern Caucasus (which encompasses Armenia, Georgia and Azerbaijan), or the West Asian region between Eastern Turkey, and northern Iran.
Several organisations have begun calling for a new kind of agriculture in which agroecosystems provide food but also support vital ecosystem services so that soil fertility and biodiversity are maintained rather than compromised. According to the International Water Management Institute and UNEP, well-managed agroecosystems not only provide food, fiber and animal products, they also provide services such as flood mitigation, groundwater recharge, erosion control and habitats for plants, birds, fish and other animals.
Investment in fine wine has attracted those who take advantage of their victims' relative ignorance of this wine market sector. Such wine fraudsters often profit by charging excessively high prices for off-vintage or lower-status wines from well-known wine regions, while claiming that they are offering a sound investment unaffected by economic cycles. As with any investment, thorough research is essential to making an informed decision.
Adulteration is a legal term meaning that a food product fails to meet the legal standards. One form of adulteration is an addition of another substance to a food item in order to increase the quantity of the food item in raw form or prepared form, which may result in the loss of actual quality of food item. These substances may be either available food items or non-food items. Among meat and meat products some of the items used to adulterate are water or ice, carcasses, or carcasses of animals other than the animal meant to be consumed.
