S1, E9: The nuns are discouraged by their inability to collect funds. A little boy's lemonade stand and the taste of sea grapes inspires Sister Bertrille to put the convent in business. While Mother Superior is away, the nuns decide to bottle the juice. Sister Bertrille finally persuades Carlos and Luis Fierro to share marketing rights, not specifying the product. The convent basement becomes a bottling plant, with nuns and children treading grapes. Mother Superior returns and gives reluctant permission. After much work and mishaps, Carlos samples the "Nectar of San Tanco." Feeling nobody will buy sea grape juice, Carlos backs out. To stay in business, Sister Bertrille gives her creditors a share of the enterprise and buys a business license. While Sister Bertrille is away, Fierro decides he can't sell the juice. He changes his mind when Sister Bertrille, trying to catch up with him, takes to the air. Sure she has been propelled by "Nectar of San Tanco,' Fierro orders four cases. While delivering it, Carlos' launch is searched by a Customs Agent. He samples the juice that has fermented, and arrests Carlos for smuggling wine. Meanwhile, Sister Bertrille learns that sea grape juice rapidly turns to wine and then to vinegar. The authorities are certain the convent is a front for Carlos' smuggling. When Sister Bertrille offers some "Nectar" all charges are dropped after the inspector finds it is vinegar. Fierro buys the vinegar, netting the nuns $19.75. Then the license man demands $20 for a vinegar license. Sighing, Carlos puts up the missing quarter.
