Gu jing Gong 20Yr comes from a small, heritage production zone within the historic brewing site park, shaped by Ming Dynasty-era pits with limited output. Only a select portion taken 10–20 cm above the base—where natural activity is most vibrant—is chosen and developed over an extended 180-day transformation period, prioritizing quality over volume. Crafted under the guidance of masters with over 30 years of experience and refined through collective expertise from nine national-level judges, it presents a deeper, fuller, and more comfortable profile. The packaging features gold-edged detailing, a gold nameplate, and an embossed flying dragon on the bottle, symbolizing prestige and heritage.

古井贡酒年份原浆二十年源自酿酒遗址公园内的小产区，依托明代传承至今的老窖池孕育而成，因产量稀少而尤显珍贵。甄选距池底约10–20公分处的核心酒醅，此区域微生物最为活跃，并经过长达180天的自然转化过程，以牺牲产能换取更高品质。由拥有30余年经验的资深老师傅亲自把关，择时摘取精华部分，再由九位国家级评委共同调配，使整体表现更加丰满、醇厚且舒适。包装盒采用金色边框与金色标牌设计，瓶身饰以游龙浮雕，尽显典雅与尊贵。
