If you sip a wine and there's so much tannin and acidity bombarding your taste buds that you can't even taste the fruit, it's safe to call it austere. Such underdeveloped wines need more time in the bottle to soften and achieve better balance, richness, and complexity. Some white wines, however, aim to be austere, such as a very dry, light-bodied, and noticeably acidic French Chablis.
