Amplification of terahertz plasmons in a pair of parallel active graphene monolayers is studied theoretically. Plasmon wave in symmetric double-layer graphene structure splits into two branches with a symmetric and an antisymmetric distribution of tangential to graphene component of the electric field across the plane of symmetry of the structure. It is shown that normalized to the wavelength terahertz plasmon amplification factor of the symmetric mode in the double-layer graphene structure could be greater than that in a single graphene layer by 4 orders of magnitude.
