Definition - What does Potent mean?
To describe a wine as potent, is to say that the wine is possessing bold character. It may be as strong on the nose in aromas and in its bouquet as it is on the palate and on the finish. In a more specific context, a potent wine may be one which is out of balance and shows strong alcohol.
WineFrog explains Potent
Potent is a descriptor used often to describe young wines, as they lack in maturity to develop more refined characters. If a wine is potent due to an imbalance in alcohol, meaning the alcohol is too apparent, it is rare that such a wine will mature and become balanced. Other wines which are potent on the nose, the palate and finish have potential for aging as they possess strong characteristics which can subdue and develop with proper aging.
