What does "good ole" mean?
"Good ole" (or "good ol'") is short for "good old," which is a casual expression used to refer to a familiar thing, person, or place with affection. In the case of the video, the speaker says "good ole tap" to imply that he frequently uses this garlic peeling method, and looks upon it with affection. It may sound a bit strange, but native speakers commonly used this expression to refer to things in a friendly or approving way. Ex: Let's get some good ol' hamburgers for dinner. Ex: My car broke down, but good ole Jessie came by to save the day.
