Bara accompanied her across the sun every day, but Wala realized she made the earth too hot and made her stop. She journeyed to the southern mountains and brought back the sun.
Generally, the lower the pH, the higher the acidity in the wine. However, there is no direct connection between total acidity and pH (it is possible to find wines with a high pH for wine and high acidity).
Note: Sweet (unfortified) wine is usually lower in alcohol than dry wine. To be considered sweet (doux or dulce), a sparkling wine must have more than 50 grams/liter residual sugar (i.e. sugar not used in fermentation, thus lower alcohol level) or 7.5 grams per 5 oz. glass. Slightly sweet (Demi-Sec, Semi-seco) is 32-50 grams/liter.
