To combat this issue we can simply add one Campden tablet per gallon which binds to any oxygen in the wine effectively removing it and preventing oxidation. Oxidation is bad for almost any home brew and will affect the flavour and colour of the wine turning it an unappealing shade of brown in both red and white wines. Removing Chlorine From Brewing Water : All tap water you use to either brewing beer or make wine will have some form of chlorine or chloramine in it.
Adding half a Campden tablet for every 5 gallons or 20 litres of water will remove chlorine or chloramine present. The potassium metabisulfite reacts with the chlorine to break it down into chloride, sulfate, and ammonia which are not going to add undesirable flavour compounds to your home brew and in some cases are beneficial.
As a Sanitising Solution For Equipment : Potassium metabisulfite can be used as a sanitising solution although it is more cost effective if you buy powdered potassium metabisulfite.
To make a sanitising solution you will need 16 Campden tablets per gallon of water. The solution can be added to a bucket with other equipment that needs sanitising. Seal the bucket which will allow the sulphur dioxide gas to sanitise all the equipment it contacts.
The solution can then be discarded and the equipment left to dry. It is the sulphur dioxide produced that sanitises and neutralises microbes rather than the solution. Contrary to what most people believe, Campden tablets will not stop a fermentation completely so they should not be used to stabilise a wine. If you add Campden tablets whilst there is active fermentation the yeast is likely to stall but will eventually they will restart.
To stabilise a wine and prevent further fermentation follow this guide. This is a common question that is easy enough to address. When you add Campden tablets or potassium metabisulfite to wine some of the sulfites remain in the wine. You will notice that most commercial wines state on the label that the wine contains sulfites. Adding too many Campden tablets will result in more sulfites in the finished wine which will affect the flavour so we do not want to add too many.
I recommend using no more than 3 Campden tablets per gallon of wine spaced out into these three separate occasions. With just these three additions you will be well within the limits acceptable for sulfites in the finished wine and have a stable finished product.
As with any additive, there is safety information to be aware of and I always advise to follow the instructions on the package you buy. Sodium Metabisulfite is a skin and eye irritant so protection should be worn when handling it. You must log in or register to reply here. Similar threads. Campden tablets effectiveness on cold cider.
