Argon versus CO2

[Norske]

When we started our winery we consulted with the "experts" and the recommendation was to use argon. Was concerned at first due to the cost difference, but found that it really goes a long way, so cost is no longer a big issue. We use it for sparging our variable volumne tanks and bottles prior to filling.

You could also use it on your tanks when adding chemicals to mix them in. Attach it to your bottom valve and let it bubble up to blend in.

I'm thinking argon is the best choice for topping off.
