Wine photo of the week 

 An actively growing vine shoot in Portugal's Alentejo. The grapevine is a freeloader, and rather spend
energy and time growing a self-supporting trunk, it hitches a ride on trees in its native habitat, and trellis 
systems in vineyards. A vitaltool for this growth habit is the tendril, which upon contact will grasp hold of
 it - a response termed thigmotropism. Of course, vines can (and do) grow unsupported (termed bush vines).
