Suitcase Clone: Term used to refer to vine cuttings illegally smuggled into the country and used to propagate new vineyards. Most countries, including the United States, have strict restrictions on importing plant material. Imported vine cuttings must be quarantined for as long as five to seven years in the U.S. before they can be certified disease-free and released for propagation.
TCA (2,4,6-Trichloroanisole): A chemical compound that can give wine a musty, dirty, bitter, chalky character often described as moldy newspapers or damp cardboard. TCA can be formed in many ways; most consumers associate it with "corky" bottles, because corks are particularly susceptible to contamination by the compound. One common catalyst is chlorine, a widespread cleaning agent, coming into contact with plant phenols (which are found in cork and wood) and mold.
