  We re-examine the question of the entropy stored in the distribution of
primordial density fluctuations. To this end we make use of two-mode coherent
states. These states incorporate the isotropy of the distribution as well as
the temporal coherence and the semi-classical character of highly amplified
modes. They also provide a lower bound for the entropy if, as one expects,
decoherence processes erase the squeezing which originally characterized the
distribution in inflationary models. This lower bound is one half the maximal
(thermal) value. By considering backreaction effects, we also provide an upper
bound for this entropy at the onset of the adiabatic era.
