A “quick” (1 to 2 hours before the dinner party) “double or triple” decant (ending in the original rinsed 750 ml bottle) will not be sufficient? IMHO it’s always best to drink a wine when it is in a “restful state” (might not necessarily taste its best) rather than a “restless state”. (Mind you, for the most of you, you’re dealing with only 750 mls of wine or just a glass of wine and this transition from “restless” to “restful” might only take a few seconds or minutes).
When decanting there are two aspects to look at oxygen “pick-up” and “breathing”. The immediate “pick-up” of oxygen puts the wine in a “restless state”; the “breathing” returns the wine to a “restful state”. As pointed out by Otto the action of pouring is responsible for the “pick-up” (colder wine would “pick-up” more oxygen than warmer wine). “Breathing” is totally different and is governed by amount of oxygen dissolved in the wine, time of oxygen exposure, size of exposed surface area, volume, temperature and chemistry of the wine. Generally when it comes to exposed surface area, a larger surface area “breathes” more than a smaller exposed surface area, and a surface area at “rest” “breathes” less than a “disturbed” surface area. (The shape of the decanter (or head space) will determine exposed surface area). The dinner ritual itself (whether the wine is served from decanter or bottle, and lasts 1 to 2 hours maybe even a little longer) continues with this process.
