An essential ingredient in winemaking.
Sodium Metabisulfite, (often referred to as SO2, sulfites meta, or meta-bi) has several uses in winemaking. It is used at the crush, to help control the spoilage bacteria and indigenous yeast that may already be present on the fruit or the equipment. The amount used is enough to stop most of the unwanted organisms but not enough to hinder a cultured yeast, which has a higher tolerance to sulfites. This effectively “wipes the slate clean” for the cultured yeast to step in and rapidly colonize the must.
Sulfites also help to inhibit the enzymatic browning of musts and finished wines. During storage and in the bottle, sulfites at the proper levels will protect a wine by continuing to inhibit spoilage organisms, as well as by scavenging oxygen.
Campden tablets are Sodium Metabisulfite in an easier to measure format. Adds 75 ppm of sulfites at the rate of one tablet per gallon. These must be fully ground-up prior to use. Potassium Meta-bi in powder form, AD495 or AD500, is much easier to use if you have a scale and does not add sodium to your wine.
It is possible the sodium could contribute a very small salty flavor. Especially when making white wine it is preferable to add potassium over sodium since added potassium can later help with cold stabilization.
For more information refer to our MoreManuals! on Red or White Winemaking or one of the winemaking books that we offer for a complete explanation on how to properly manage sulfites.

No more chloramines!
My city water is treated with chloramines, so I bought some of these. They are easy to use and cheap.

Save money on water.
Instead of buying bottled or packaged spring water, you can convert your municipal tap water into a more ideal profile using this to remove chloramine. I have noticed fewer off flavors and a saison made with this came out great!

Removes chloramine
I was having off flavors with some of my beers using local tap water even though I have a whole house filter system. It is just a sediment filter to remove large particles. I found out that many water supplies use chloramine for purification of water and that might have been the culprit. Since using a single campden tablet in my brew water for up to 10 gallons(I think it can be used for up to 20 gallons), my beers have all seemed to be better.

Great water
As others noted this is part of my water regimen to prevent any chloramine.

Chloramine destroyer
I always crush one of these up and treat my water on brew day. It works instantly and is way too cheap to not use and risk chloramine off favors.

Cheap security policy
I am fortunate to have very good tasting water. However, I can smell a slight bit of chlorine/chloramine. So, I simply crush one of these as the instructions state and then proceed normally. My first couple of batches I did not use these and the beer tasted fine. But it is a very small cost to ensure that the chlorine/chloramine don't impact the taste of your brews. So, I now use them on all batches.
