This is the worst advice ever. If you said Madeira you’d be spot on. Port is still a wine and I can’t tell you how many people have ruined it by letting it get warm during storage. It should be treated exactly the same as any other wine.
I have wine in several coolers, racks, wood crates and now I have moved to storing some flat on the concrete basement floor. I find about a 4 degree difference, 62 vs 66 for wine on the floor verses in the open wood racks.
I have recently resorted to storing my overflow in my crawl space which is currently 57 degrees. I will have to keep an eye on it as the summer heat creeps up.
I usually buy 3 or 4 btls of something. If they need long term storage I keep 1 or 2 in my cabinett for the ready and put the other 2 or 3 in storage locker.
Perfect. That will mean you’ll need to plan on what bottles you move out of storage to drink. And there won’t be a night when one of your wife’s drunken, slob friends puts down a bottle of La Tâche.
