1. An apparatus for extracting a liquid from a container having an opening, said apparatus comprising: a liquid extraction member having a length (Le) of at least 2 inches, wherein one end of said extraction member includes a liquid extraction inlet, wherein said extraction member is configured for insertion through said opening of said container and for positioning of said extraction inlet below the surface of said liquid,a storage vessel defining a liquid storage inlet coupled in fluid flow communication with said extraction member, wherein the maximum internal diameter (Ds) of said storage vessel is greater than the maximum internal diameter (De) of said liquid extraction member, wherein said storage vessel has a maximum height (Hs), and wherein said apparatus has an Le:Hs ratio of at least 1:1;a shiftable plunger received in said storage vessel and operable to create a pressure differential between said storage inlet and said extraction inlet so as to draw said liquid from said container, through said extraction member, and into said storage vessel; andan air blocking member received in said extraction member and shiftable between an initial blocking position and a final extraction position, wherein said air blocking member presents a lowermost surface that moves through a total distance (Xb) as said air blocking member is shifted from said initial blocking position to said final extraction position, wherein said lowermost surface is positioned less than 0.25Xb from said extraction inlet when said air blocking member is in said initial blocking position,wherein said liquid extraction member and said storage vessel extend substantially perpendicular to one another, said air blocking member and said shiftable plunger are separately moveable, and said storage vessel is detachably connected to said liquid extraction member at an end of the liquid extraction member opposite said liquid extraction inlet. 2. The apparatus according to claim 1, wherein De is at least 0.1 inches and not more than 4 inches. 3. The apparatus according to claim 1, wherein Le is at least 4inches and not more than 40 inches, wherein the Le:Hs ratio is not more than 5:1. 4. The apparatus according to claim 1, wherein said apparatus has an Xb:Leratio of at least 0.5:1. 5. The apparatus according to claim 1, wherein De is at least 0.1 inches and not more than 4 inches, wherein Le is at least 4 inches and not more than 40 inches, wherein the Le:Hs ratio is not more than 5:1. 6. The apparatus according to claim 1, wherein said container is a wine bottle and said liquid is wine. 7. The apparatus according to claim 6, wherein De is at least 0.1 inches and not more than 4 inches. 8. The apparatus according to claim 6, wherein Le is at least 4inches and not more than 40 inches, wherein the Le:Hs ratio is not more than 5:1. 9. The apparatus according to claim 1, wherein said air blocking member is shiftable relative to said plunger, wherein said air blocking member is configured to create a pressure differential sufficient to draw said liquid into said extraction member when said air blocking member is shifted away from said initial blocking position toward said full extraction position. 10. The apparatus according to claim 9, wherein said container is a wine bottle and said liquid is wine. 11. The apparatus according to claim 1, wherein said air blocking member is tapered so as to become narrower towards said lowermost surface. 12. A process for extracting a liquid from a container and storing said liquid, said process comprising the steps of: (a) inserting a liquid extraction member having a length (Le) of at least 2 inches into a container to a depth such that a liquid extraction inlet of said extraction member extends below the surface of said liquid received in said container;(b) creating a pressure differential between said extraction inlet and a storage inlet of a storage vessel by displacing a shiftable plunger to thereby cause at least a portion of said liquid to flow from said container, through said extraction member, and into said storage vessel, wherein the maximum internal diameter (Ds) of said storage vessel is greater than the maximum internal diameter (De) of said liquid extraction member, wherein said storage vessel has a maximum height (Hs), and wherein an Le:Hs ratio is at least 1:1; and(c) during at least a portion of step (b), shifting an air blocking member in said liquid extraction member from an initial blocking position to a final extraction position, wherein said air blocking member presents a lowermost surface that moves through a total distance (Xb) as said air blocking member is shifted from said initial blocking position to said final extraction position, wherein said lowermost surface is positioned less than 0.25Xb from said extraction inlet when said air blocking member is in said initial blocking position,wherein said liquid extraction member and said storage vessel extend substantially perpendicular to one another, said air blocking member and said shiftable plunger are separately moveable, and said storage vessel is detachably connected to said liquid extraction member at an end of the liquid extraction member opposite said liquid extraction inlet. 13. The process according to claim 12, wherein De is at least 0.1 inches and not more than 4 inches. 14. The process according to claim 12, wherein Le is at least 4inches and not more than 40 inches, wherein the Le:Hs is not more than 5:1. 15. The process according to claim 12, wherein De is at least 0.1 inches and not more than 4 inches, wherein Le is at least 4 inches and not more than 40inches, wherein the Le:Hs is not more than 5:1. 16. The process according to claim 12, wherein said container is a wine bottle and said liquid is wine. 17. The process according to claim 16, wherein De is at least 0.1 inches and not more than 4 inches. 18. The process according to claim 16, wherein Le is at least 4inches and not more than 40 inches, wherein the Le:Hs ratio is not more than 5:1. 19. The process according to claim 12, wherein step (b) includes first shifting said air blocking member from said initial blocking position to said final extraction position and then shifting said plunger away from said inlet of said storage vessel. 20. The process according to claim 19, wherein said container is a wine bottle and said liquid is wine.
