Acids in wine ripened grapes. While concentration varies among grape varieties, it is usually found in higher levels with red wine grapes. The acid is created as a byproduct of the metabolization of nitrogen by yeast cells during fermentation. The combination of succinic acid with one molecule of ethanol will create the ester mono-ethyl succinate responsible for a mild, fruit aroma in wines. Acidity is highest in wine grapes just before the start of "veraison", which ushers in the ripening period of the annual cycle of grape vines. As the grapes ripen, their sugar levels increase and their acidity levels decrease. Through the
Energy Brix Power Station stations. The National Pollutant Inventory provides details of other pollutant emissions, but, as at 23 November 2008, not CO2. Energy Brix Power Station The Energy Brix Power Station was a brown coalfired thermal power station located at Morwell, in Victoria, Australia. The power station was used to supply electricity for the retail market, as well as the production of briquettes in the adjacent Energy Brix briquette works. It was shut down in August 2014 and is currently the earliest surviving large-scale power station designed to provide electricity to the state electricity network.
