While the iconic character MacGyver was known for his ingenuity and problem-solving skills, his relationship with alcohol was never explicitly addressed in the original television series.
There are no scenes depicting MacGyver consuming alcohol, nor are there any instances where his drinking habits are mentioned in dialogue. While this doesn't definitively prove he abstained from alcohol altogether, it suggests that it wasn't a significant part of his life or personality.
It's important to note that the show's creators aimed to portray MacGyver as a positive role model, particularly for young viewers. This likely influenced their decision to avoid depicting him engaging in potentially harmful behaviors like excessive alcohol consumption.
Therefore, based on the available information from the original series, it's safe to say that MacGyver's drinking habits were not a prominent aspect of his character.
