Put egg yolks, red wine vinegar, and Dijon mustard in food processor and pulse a few times until the egg yolks are all blended.
Turn on low and then slowly drip a drop at a time the oil in while blending until it takes on the consistency of mayo. Then slowly add a stream of the oil while blending until it all is incorporated.
Transfer to mason jar and refrigerate immediately.
The time that the mayo will last depends on the freshness of your eggs. For standard store bought eggs, at least a week - two weeks. Farm fresh eggs may allow it to last longer.
