How do you identify a quality green tea?

To identify quality green tea, look for vibrant green leaves that are intact and not overly broken or dust-like, which indicates freshness. The aroma should be fresh and vegetal, not stale or overly grassy. Additionally, high-quality green tea often has a smooth, rich flavor with subtle sweetness, lacking any bitterness. Finally, check for information on the origin and production methods; reputable teas often come from renowned regions and adhere to traditional processing techniques.
