'Techniques for Chemical Analysis and Quality Monitoring during Winemaking'
P. Iland, A. Ewart, J.Sitters, A. Markides & N. Bruer
A great reference guide designed to be used in the laboratory as well as the
winery and vineyard. It contains a broad range of juice and wine analysis
techniques, identifies and explains vineyard and cellar operations, as well as
providing instruction for fining trials and stability assessments. It is suitable for
beginners or advanced levels and is a must with every new laboratory set up |

DETERMINATION OF TITRATABLE ACIDITY |
|
| |
|
|
Titratable acidity also known as 'Total Acidity' is a measure of all hydrogen ions
free in solution, bound to disassociated acids and bound to anions. It differs
from pH which only analyses the free hydrogen ion component. In Australia
titratable acidity is measured to a predetermined end point of 8.2pH and the
total value is expressed as tartaric acid despite results being the sum of all
acids contained within the wine. |

MONITORING MALIC ACID:
THIN LAYER CHROMATOGRAPHY (TLC) |
|
| |
|
|
Qualitative measurement identifying acids present within a wine, a means of monitoring the malolactic fermentation process. Using a set of standards this method targets both malic and lactic acids, although other acids (i.e. tartaric
acid) can also be detected. All components of this kit are manufactured according to the procedure developed and recommended by Dr R. Harris (Brindabella Hills Winery). |
|
|
|
 |
|
|
MICROBIAL ANALYSIS: MICROQIT |
|
| |
|
|
A cost-effective and convenient tool for high quality microbiological analysis.
Using this system there is no need to prepare media or invest in expensive
specialist equipment. All items are contained in one easy to use kit. All
components are sterile and in the right proportions to minimise waste.
Kits are prepared from a range of media to target particular organisms
including wine yeast (Saccharomyces), spoilage yeasts
(Dekkera/Brettanomyces and Hanseniaspora/Kloeckera), lactic acid bacteria
(Lactobacillus and Oenococcus) or acetic acid bacteria (Acetobacter and
Gluconobacter). |
|
|
|
 |
|
|
SULPHUR DIOXIDE (SO2) DETERMINATION: ASPIRATION |
|
| |
|
|
Sulphur dioxide (SO2) is the most common preservative used in winemaking
and can be added throughout the process to grape juice, must and/or wine.
Levels of SO2 are affected by numerous catalysts which is why this analysis is
one of the most important. This method is based on aspiration, liberating the
SO2 from the sample for measurement by titration. |

DETERMINATION OF ALCOHOL: EBULLIOMETRY |
|
| |
Alcohol levels in wine are a labeling requirement and therefore must be
analysed. Measurement is expressed as percent (%) ethanol by
volume/volume (v/v) at 20°C. One method of determining alcohol content is
ebulliometry which calculates alcohol %v/v @ 20°C by analysis of the boiling
point. It is suitable for wines up to 16%v/v |
| |

|

 |
|
|
DETERMINATION OF ALCOHOL: DISTILLATION |
|
| |
Alternative, precision method for determining alcohol content. This method
separates the alcohol component from the wine sample by distillation. The
distillate is then measured for specific gravity by hydrometry. |
| |
|

DETERMINATION OF VOLATILE ACIDITY: MARKHAM STILL |
|
| |
Volatile acidity indicates wine spoilage bacteria and in high concentrations dominates the aroma profile of a
wine. The method analyses the level of volatile acid present in the sample by removing volatile acid (mainly
acetic acid) from the fixed acids (e.g. tartaric acid) by steam distillation. The distillate is then analysed and
quantified by titration and expressed as acetic acid. Sensory evaluation is also a very important part of volatile
acidity determination and should be used throughout the wine making process. |

UNSTABLE PROTEIN ASSESSMENT: BENTOTEST |
|
| |
Protein instability is primarily a problem in white wines, a result of naturally
occurring proteins in the wine being denatured creating haze in the bottle,
generally due to temperature fluctuations during storage. Proteins are treated
prior to bottling with bentonite, however in order to determine addition rates,
fining trials must be carried out.
Bentotest is an acid formulated specifically to change colour in the presence
of protein. It assists in determining the addition rates of bentonite, it is a
simple to use, low cost, fast acting analysis. |
| |
|
| BENTOTEST KIT INCLUDES: |
| 50ml Bentotest reagent |
or |
250ml Bentotest reagent |
| 1 x 10ml Volumetric pipette |
or |
2 x 10ml Volumetric pipettes (1 spare) |

or |
2 x 1ml Volumetric pipettes (1 spare) |
| 4 x Test tubes |
| 1 x Test tube holder (6 hole) |
|
|
|
|
 |
|
|
UNSTABLE PROTEIN ASSESSMENT: HEAT TEST |
|
| |
Protein stability can also be analysed by extended heating of wine samples,
simulating the extreme conditions that wine may be exposed to during
storage. In the presence of protein a haze will form in the heated sample.
Protein stability analysis aims to remove all unstable proteins however testing
should always be performed in conjunction with sensory analysis. Often
desirable characteristics (eg aroma and flavour) of the wine are also affected
by bentonite treatment, addition rates should be a compromise between
stabilisation and wine quality. |
