Red ports

In terms of color, red ports vary from deep purple to light gold (Fig. 5.10). Designations of full, medium full or ruby, medium tawny, tawny, and light tawny are used to define each type. White ports come in various shades (pale yellow, straw, and golden white), all intimately related to the winemaking technique used. 

Wine Group 2 - Forced Aging experimental protocol This protocol is similar to that of a previous study (5/ Red port wine, 2 years-old (8L), with a pH=3.7, a dissolved oxygen content of 4.2 mg/L, an instantaneous potential of 222 mV and a free SO2 level of 17 mg/L, was prepared in order to analyze the effect of parameters believed to be important in the aromatic modification of port wines, namely temperature, oxygen concentration, pH and SO2 concentration (Figure 1). 

OA (tartaric, malic, lactic, succinic, and acetic acids) in white and red port wines Acetic, citric, fumaric, lactic, malic, oxalic, succinic, and tartaric acids, nitrate and sulfite ions in white and red wines OA (oftartaric, malic, acetic, succinic, and lactic) in wine... 

Statistical Analysis. Application of statistical methods to analytical data on wines has not been common. Oliveira (1941), however, made a detailed statistical study of the analyses of various constituents in 600 white and 1071 red port wines. The frequency curves are somewhat asymmetric, particularly for the volatile acidity this is, perhaps, to be expected in dessert wines—where a small constant amount is formed during fermentation and where the quantity present increases slowly during aging. The averages were ... 

Amounts. In fifty-six genuine red ports Vasconcellos (1940a) found 0.01 % to 0.16% tannin. In sixteen white ports the range was from 0.01 % to 0.04%. These values should be multiplied by 2.4 to be comparable to those of the Neubauer-Loewenthal procedure. Other values are reported in Table XVIII.

Condenser The condenser has several port connections. The top port is normally vapor product while the bottom red port is liquid product and the... 

Physical properties of Fullerene Cyg It does not melt below 360°, and starts to sublime at 350° in vacuo. A reddish-brown solid, greenish black in thicker films. Solns are port-wine red in colour. Mixtures of Csq and C70 are red due to C70 being more intensely coloured. It is less soluble than Cso in but also dissolves... 

The purified fullerenes have very attraetive eolours. Thin films of Cgo are mustard-eoloured (dark brown in bulk) and solutions in aromatie hydroearbons are a beautiful magenta. Thin films of C70 are reddish brown (greyish blaek in bulk) and solutions are port-wine red. C76, C78 and Cg4 are yellow. 

Nickel and palladium react with a number of olefins other than ethylene, to afford a wide range of binary complexes. With styrene (11), Ni atoms react at 77 K to form tris(styrene)Ni(0), a red-brown solid that decomposes at -20 °C. The ability of nickel atoms to coordinate three olefins with a bulky phenyl substituent illustrates that the steric and electronic effects (54,141) responsible for the stability of a tris (planar) coordination are not sufficiently great to preclude formation of a tris complex rather than a bis (olefin) species as the highest-stoichiometry complex. In contrast to the nickel-atom reaction, chromium atoms react (11) with styrene, to form both polystyrene and an intractable material in which chromium is bonded to polystyrene. It would be interesting to ascertain whether such a polymeric material might have any catal3dic activity, in view of the current interest in polymer-sup-ported catalysts (51). 

In 1747, the elder tree was banned in Portugal in an attempt to prevent its being used as a wine adulterant, even though it was therapeutic and caused no harm. In 1899, an American soldier visited a doctor in Prague, Czechoslovakia, and informed him that whenever he got drunk on dark red cheap Czech port wine, his rheumatism pains would disappear for...

Fig. 5 The current River Rhone temperature regime (grey, black) as a result of damming (and partly climate change) compared with daily data (red, blue) from one century ago (1886 and 1904/5). The data has been collected at Porte du Scex by [19], by [18] and by [16] for 1886 (blue), 1904/5 (red), and in the last decades (grey, black), respectively. The red dots are daily values (afternoon). The black bars represent minima and maxima for the period 1982-2002. The hydropower operation has a smoothing effect on the temperature below the outlets in the River Rhone In winter, the current temperature is about 2°C above natural (warming from prewarmed reservoirs) and in summer about 1 °C cooler (less riverbed friction electricity production). The annual average remains almost constant. Details in [10]...

In the sixteenth century this openness was demonstrated not only by the Turkish connection but by the number of Arab and Gujarati scholars making Aceh their home. In the first half of the seventeenth century when we have the first English and Dutch reports, Aceh emerges as a major port of the Bay of Bengal, with traders from the Red Sea and Pegu... 

Hydrochloric add, on being boiled with lignin, turn red, and ultimately brown. In the solid state, it be-. comes black, but does not dissolve in the acid. When this substance is washed and dried, it burns with flame, bowing that it is only modified lignin, and not entirely carbonized. Fused potossa, or a strong solution of this alkali, changes a portion of the matter into oxalic and acetic acide, which combine with the base the alkaline liquor, when treated with acids, ports with a modified lignin which is blued by iodine.
