I have to admit, I have never made a vegetable stock although I have a number of recipes to try. We use vegetarian bouillon for many dishes. I have not yet aquired the habit of making my own. I have been very pleased with both Knorr and HerbOx brands. One difference between the two is that each individual Knorr cube is for two cups of water, while each HerbOx cube is for one cup of water. So, depending on the cubes you are using, you can decide how many you need.
Since I haven't yet gotten into preparing fresh vegetarian stock, I have found a few brands of vegetarian flavorings that make very acceptable bouillon. Two particular favorites are Knorr and Better Than Bouillon. Both are definitely staple items in our kitchen.

The alcohol evaporates while cooking, leaving just the flavor enhancement as needed when included. I buy cooking wines in the grocery store, such as Holland House by label. Though many serious cooks would frown on this, taste is the test, and the results get very high marks in our experience.
This is simply the water that's left after cooking potatoes. I usually cook potatoes in just the amount of water needed so that it evaporates by the time the potatoes are finished cooking.

It can be stored in the refrigerator and then used for soups, numerous baked goods, and in ways perhaps not yet discoverd. Just use your imagination mixed with a cooking sense for good taste.
