Needless to say, you will first of all require formal education to whichever level you can get to. Just because wine does not involve plenty of education is not to mean that wine merchants should be dumb. They should be sharp because their customers rely heavily on them to bring them the best wines in the market. Every business calls for some knowledge of management skills; and therefore, you will need to acquire some training. As a skill and as a tool, you should have a lot of knowledge about wine so that you can know what is new in the market. This will also attract customers your way once they learn that you are knowledgeable about wine. For online wine merchants, they should be handy with computer skills as they will pry their trade with the computer. They will also have to be good with the internet so that they can surf from one online market site to another.
