I am looking for a couple of canisters of Private Preserve, which is basically a canister medical grade compressed nitrogen, carbon dioxide and argon that you spray on top of opened wine to preserve what's left in the bottle. I know I've seen this in Toronto before but for some reason now can't find it and haven't seen it lately at my local LCBO (although could swear I saw it there in the past). Ideally I would like to get it on the subway line. I don't see it on the Wine Establishment's website. Thanks!
