Description of Test |
WA 010 |
SUGAR CONCENTRATION
(Soluble solids) |
500ml |
$10.00 |
The level of sugar in juice is determined by Hydrometry.
The result is expressed in Baume @ 20C.
|
WA 020 |
PH of JUICE/WINE |
200ml |
$7.50 |
PH is related to the concentration
of acid in the wine and is a basic parameter of wine quality.
|
WA 030 |
TOTAL ACIDITY (TA) |
200ml |
$13.00 |
This titration procedure is used to determine the total acid level in the juice or wine.
The result is expressed in terms of g/L Tartaric acid.
|
WA 040 |
PH (JUICE) and TOTAL ACID ADDITION TO REQUIRED PH LEVEL (This analysis is essential prior to fermentation)
|
1.5 litres |
$16.50 |
|
WA 050 |
RESIDUAL (Reducing) SUGARS
by REBELEIN METHOD |
30ml |
$35.00 |
This test is usually conducted after fermentation has finished in order to determine the level of total reducing sugars in the wine.
Results are expressed in g/L R.S
|
WA 060 |
PRESENCE OF MALIC ACID
- TLC METHOD |
30ml |
$14.50 |
This test is used to determine the presence/absense of Malic Acid in the wine, usually once the Malo-lactic fermentation is finished.
|
WA 070 |
FREE/TOTAL SO2 - RANKINE ASPIRATION METHOD |
200ml |
$13.50 |
Maintaining the correct level of
Free SO2 (Sulphur Dioxide) in
wine is critical to avoiding both
oxidation and bacterial spoilage.
|
WA 080 |
ALCOHOLIC - DISTILLATION/HYDROMETRY |
750ml or
1 Litre |
$35.00 |
By Distillation followed by Hydrometry. Results expressed to the nearest 0.1% v/v
|
WA 090 |
BENTONITE FINING TRIAL |
500ml |
$20.00 |
For this test please supply a
sample of the bentonite (100g)
if not using Volclay – granular.
Recommended rate of addition of bentonite is given as gram/L
of wine.

SENSORY EVALUATION
(Includes testing of colour, nose, palate and any wine faults) |
500ml or 750ml FULL BOTTLE |
$8.95 |
The organoleptic qualities of the wine are examined and the wine evaluated.
The wine is also tested for any wine faults such as VA, H2S, Oxidation, High SO2 levels, etc.
