This is the secret Greek dressing recipe from the pizzeria that I work at. The recipe makes almost a gallon but can be scaled down easily. It can be used for picnics and travels very well, since it doesnt need to be refrigerated. This is the best dressing I have ever tasted, people offer to buy it constantly, but if we sold it we wouldnt be able to make enough to use in the restaurant!

Vigorous whisking forces oil and red wine vinegar into a temporary suspension, aided by the mucilage present in ground mustard seed acting as a natural surfactant. Without emulsifiers, oil droplets coalesce rapidly due to surface tension. Mustard holds these droplets apart by lowering interfacial tension.
Commercial-scale dressings rely on dried oregano and basil because dehydration concentrates essential oils like carvacrol and thymol. Fresh herbs contain up to 90 percent water, which dilutes acidity and introduces unwanted enzymes that degrade chlorophyll within 24 hours at room temperature. Dried components rehydrate slowly in the oil-acid matrix, releasing flavor compounds over hours rather than minutes.
Room temperature storage remains viable because high concentrations of acetic acid in red wine vinegar create an inhospitable pH environment for pathogens. Olive oil protects the submerged spices from oxidation by forming a barrier against ambient oxygen. Batches stored in airtight containers maintain peak aromatic potency for up to six months without refrigeration.
