Wine

Wine (from Latin vinum) is an alcoholic beverage made from fermented grapes or other fruits. Due to a natural chemical balance, grapes ferment without the addition of sugars, acids, enzymes, water, or other nutrients.Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide. Different varieties of grapes and strains of yeasts produce different styles of wine. These variations result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the terroir (the special characteristics imparted by geography, geology, climate and plant genetics) and subsequent appellation (the legally defined and protected geographical indication used to identify where the grapes for a wine were grown), along with human intervention in the overall process.

Wine has been produced for thousands of years. The earliest evidence of wine to date was found in the country of Georgia, where 8000-year old wine jars were uncovered. Traces of wine have also been found in Iran with 7,000-year-old wine jars and in Armenia with the 6100-year old Areni-1 winery, which is considered to be the earliest known winery by far. The earliest form of grape-based fermented drink however, was found in northern China, where archaeologists discovered 9000-year old pottery jars. Wine had reached the Balkans by c. 4500 BC and was consumed and celebrated in ancient Greece, Thrace and Rome. Throughout history, wine has been consumed for its intoxicating effects, which are evident at normal serving sizes.

Front of House

In the performing arts, front of house is the portion of a performance venue that is open to the public. In theatre and live music venues, it is the auditorium and foyer, as opposed to the stage and backstage areas. In theatre, the front of house manager is responsible for ticket sales, refreshments, and making sure auditorium is set out properly.

Live venues

Lighting and sound operators, excluding the monitor engineers, are normally positioned in a small sectioned-off area front of house, surrounded by the audience or at the edge of the audience area. From this position they have unobstructed hearing and a clear view of the performance, enabling the operation of the main speaker system, show control consoles and other equipment. In this case Front of House can refer to both the general audience/public area or to the specific small section from where the show is mixed.

The front of house speakers are the main speakers that cover the audience, and the front of house desk is the desk that generates the front of house audio mix. In smaller venues the front of house desk may also produce foldback (monitor) mixes for the monitor speakers onstage, whereas in larger venues there will normally be a second mixing desk for monitor control positioned just off the side of the main stage. The audio engineer that designs the front of house sound system and puts it into place for the show/event is the system engineer, and this role is often separate from the person who operates the mixing desk who is often employed by the band directly.

Sodium bicarbonate

Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate) is a chemical compound with the formula NaHCO₃. It is a salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate). The natural mineral form is nahcolite. It is a component of the mineral natron and is found dissolved in many mineral springs. It is among the food additives encoded by European Union, identified as E 500. Since it has long been known and is widely used, the salt has many related names such as baking soda, bread soda, cooking soda, and bicarbonate of soda. The word saleratus, from Latin sal æratus meaning "aerated salt", was widely used in the 19th century for both sodium bicarbonate and potassium bicarbonate.

History

The ancient Egyptians used natural deposits of natron, a mixture consisting mostly of sodium carbonate decahydrate, and sodium bicarbonate. The natron was ground up, solvated, and used as paint for hieroglyphics.
