Alcohol by volume is a worldwide standard measure of how much alcohol is contained in a given volume of an alcoholic beverage. Alcohol (ethanol) is the main product of primary fermentation and a critical measurement in the determination of tax rates as well as aromas, flavors and stability. Alcohol measurement is useful in fermentations where high potential alcohol is a concern. It is also useful in advance of secondary (malolactic) fermentation to determine the correct bacteria strain selection.Includes

We plate 250mL of the bottled samples through a sterile system onto WL nutrient media in a flow hood, then the plates are incubated at 30*C for seven days with a reading at Day 3 and Day 7. We then report CFU (colony forming units) per/250mL and if any are present, we examine them under microscope to determine the morphology and report the findings, along with a photo of the microbes under microscopy.

This test measures the total concentration of calcium, a naturally occuring mineral. Calcium present in water used to decrease alcoholic strength may be a cause of precipitates in spirits. Calcium is also found in fruits such as grapes as well as wine. The calcium present is due to uptake from the soil and is used as a nutrient during fermentation. High concentrations of calcium can result in calcium tartrate instability. Calcium is naturally present in water. It may dissolve from rocks such as limestone, marble, calcite, dolomite, gypsum, fluorite and apatite. Calcium is a determinant of water hardness, because it can be found in water as Ca2+ ions. Magnesium is the other hardness determinant. In some cases, additional calcium ions may need to be added to adjust water chemistry for brewing beer.Includes

This test measures the total concentration of Cobalt, a naturally occurring mineral that is part of vitamin B12. Low levels of Cobalt have been shown to increase fermentation performance. At high levels, Cobalt is considered a contaminant and investigation may be needed in order to prevent undesirable levels. Cobalt concentration may increase due to bentonite being used as a technological aid for clarification purposes as well as the attack of alloys during filtration. Cobalt can also show increased levels based on geographic region and industry.
