I am afraid that the only appropriate answer is threefold to the OP
-
Most of us here are passionate about collecting/drinking/sharing the hobby that is wine. You will NOT get a friendly reception to a question that is “How do I make big bucks collecting and selling wine?” This will strike many of us as being akin to rolling into a tasking room in wine country and saying “How 'bout some free pours of juice so I can get loaded and score with the cute girl behind the counter?”

Trying to make money buying and selling wine for a profit? You are about 15 years late to the party. There is no easy way to cash in at the current time. There have been too many books, articles, stories written about this topic that have led many would be profiteers down the rabbit hole. Hopefully these types of buyers have gotten burned soundly and will move on. Chinese buyers pushed the last big wave of speculation, who knows if they will be back?

Take into account the hostile/snarky responses here reflect the personalities of the posters. Some responses will try to be helpful to get you accurate information about the topic. There is a lot of comparison in wine investing to gambling, with the same risks. If you just want a safe way to make money, put it into triple tax free muni bonds, not the wine market. Most of us here will spend many multiples of $$$ drinking and sharing wine as opposed to ANY degree of profit that may come from being in the right place at the right time with a bottle of wine.
Hope this advice will save you a lot of time and money. If you get interested in something MORE than just the profit side of wine, stick around and you will learn a LOT about this passion…
