iSi Whipped Cream Charger- Weird Taste

I got an iSi CO2 whipped cream charger today at a garage sale with several boxes of really old co2 cartridges. I cleaned it all well, (it already seemed immaculate,) and put in sugar, vanilla, and fresh cream. Then I charged it.
Well, the whipped cream tastes STRANGE. Kind of fizzy like soda water. Anyone have any experience with this? I tried shaking the canister more, tried letting it rest for an hour, tried letting it warm up a bit at room temperature. Could it be the old co2? This seems strange, but I can't figure it out. Thoughts?
Thanks chowhounders!

  1. iSi CO2 is used for carbonating liquid beverages. You need to purchase the iSi cream charger cartridge. It will say CREAM on it. We ruined 3 quarts of whipping cream before we finally figured it out. It tasted absolutely terrible. We won't make that mistake again.

      Thank you SO much! I had no idea. It tastes really creepy. My garage sale stash came with some of the cream ones too- I'll try that next.
