How can I tell if my sourdough starter is alive?

You can check to see if your sourdough starter is alive by looking for signs of activity. If the mixture has bubbly, it is likely that your starter is active and ready to use. You may also be able to feel a slight rise in the dough when you mix it. Additionally, you can smell the aroma of fermentation from the starter, which should be pleasant and slightly acidic.
