Tobacco cut filler is subjected to extraction conditions using tap water as a solvent using a counter current, counter rotating, upwardly inclined extraction apparatus. The extracted tobacco material which is collected undergoes no significant physical degradation while having a high level of water extractables removed therefrom. Aqueous tobacco extracts having relatively high levels of tobacco extractables also can be provided. Extracted tobacco material also can be re-equilibrated with a tobacco extract by contacting the extracted tobacco material and an aqueous tobacco extract in a counter current, counter rotating, upwardly inclined extraction apparatus.
