A single step method of converting lignocellulosic materials to sugars including combining and mixing a low solids content lignocellulosic material with concentrated sulfuric acid, allowing the reaction to proceed and then separating the sulfuric acid and sugar solution from the reaction product. A modified single step method includes dilution of the reaction product with water, followed by continued reaction and subsequent separation of the sulfuric acid and sugar solution.
