These aren’t tiers of the same product — they’re built around two different drinking patterns.
A vacuum pump suits the common case
Removing air from an opened bottle with a manual pump costs a fraction of a gas system and covers most households’ actual pattern: open a bottle, finish it within a few days.
A gas system suits a specific pattern
Coravin-style systems pour through a stopper without removing the cork, keeping air out entirely — genuinely useful for pouring small amounts from the same bottle repeatedly over weeks, at a real ongoing cost in gas capsules.
Cost scales very differently
A vacuum pump is a one-time purchase, reused indefinitely. A gas system costs many times more upfront and carries a recurring capsule expense once the included ones are used.
What we would not do
Buy a gas system for a household that finishes most bottles within a few days of opening. That’s exactly the case a cheap vacuum pump already handles well — the gas system’s advantage only shows up over genuinely long preservation windows.
What readers ask us
Is the gas system ever worth it for everyday wine?
Rarely — its real advantage is preserving expensive or special bottles poured from occasionally over a long period. For everyday wine finished within a few days, the cost premium doesn't buy a proportional benefit.
