Not every wine is capable of improving and / or staying good for that time, regardless of how good your storage situation is. Tannin is one of the components that play a large role in aging, along with pH. Lots of wines produced to be “early drinkers” don’t focus on tannin extraction, or even avoid it, typically aren’t going to age well.
Young wines with lots of tannins that aren’t tasting very good early on, if you’ve made one of those, you may have a candidate. As mentioned above, the storage of the wine is also a part of the puzzle, a properly sulfited wine, bottled and corked to last, in a vibration free environment around 55 F, 65% - 75% RH, will do nicely for many, many years. Will it be awesome in 30 years? I cannot say, but I’ll let you know in 25 years.
