Measuring co2 in wine.
Measuring carbon dioxide can be tricky but important to monitor during the winemaking and bottling process.
Pour it in a conical flask add the same volume of the naoh 50 solution as for the blank seal the flask and mix thoroughly.
The carbodoseur provides fast and easy analysis of dissolved carbon dioxide in wine samples and is able to be used by staff with limited technical training by following the steps below.
The installation can be easily made by means of 1 single varivent fitting with no need of any bypass or pump.
Measuring carbon dioxide in the winery can be done a number of ways but the quickest and easiest of these is to use a carbodoseur.
Fermentation the chemical process that uses yeast to convert sugars to ethanol is at the heart of the wine production process and requires accurate co measurement to ensure quality wines.

The importance of measuring co2 in wine production.
A fairly safe amount for protection of the wine is either 5 ppm for red wines or 8 ppm for white wines.

For better and worse carbon dioxide co 2 is implicated in several aspects of still.
The level of dissolved carbon dioxide co 2 in wine has a significant sensory impact in general co 2 enhances freshness and acidity perceptions decreases sweetness intensifies bitterness and astringency and can lead to prickliness.
If you know the ph simply make sure you have the corresponding level of free so2 or slightly more present in the wine during storage and bottling.
To avoid losing carbon dioxide ensure that the flasks handling the sample are always at low temperature near 0 c.
Measurement of carbon dioxide.
Depending on the wine too little co 2 can make.
The simplest method is the use of carbodoseur.
Temperatures and conditions in wineries are very carefully controlled to ensure that fermentation does not occur too fast distorting the flavour and.
The amount of free so2 needed is based on the ph of the wine.

Carbon dioxide in wine can be measured using a variety of analytical tech niques and instruments including the carbo doseur titration blood gas analyzers and co 2 specific electrodes.
Taking care not to lose carbon dioxide take 100 ml of the wine at 5 c using a measuring tube.
