About this water

Snow-fed metamorphic geology (schist/phyllite), steep pocket water, and a compressed post-snowmelt season make it fundamentally different from the Cazorla limestone cotos down in Jaén. June is usually the core month, with May and July as shoulders depending on snowpack — a much shorter, sharper window than the longer warm season on the Jaén limestone rivers.
