Acids in wine responsible for the sour taste of vinegar. During fermentation, activity by yeast cells naturally produces a small amount of acetic acid. If the wine is exposed to oxygen, "Acetobacter" bacteria will convert the ethanol into acetic acid. This process is known as the “acetification” of wine and is the primary process behind wine degradation into vinegar. An excessive amount of acetic acid is also considered a wine fault. A taster's sensitivity to acetic acid will vary, but most people can detect excessive amounts at around 600 mg/l. Ascorbic acid, also known as vitamin C, is found in young wine grapes
Darkinjung language ordered from the publisher, Muurrbay Language Centre at http://www.muurrbay.org.au/muurrbay-resources/. Much of our understanding of Darkinjung comes from papers published by R.H. Mathews in 1903. When analyzing these sources, we may generalize that there were around 15 consonants phonemes, and approximately 3 vowels. In Darkinjung, like many Australian languages, b, d, and g are interchangeable with p, t, and k and will not change the meaning of the word. The fact that this table shows b, d, and g is arbitrary. Darkinjung makes use of what Mathews refers to as "tags," or suffixes to denote relationships between objects in sentences. Number
