Bosc
Bosc are an elegant variety, with distinctive characteristics that set them apart from other pears. Although produced in less volume than Bartletts or Anjous, Bosc are almost as well known. Those who are familiar with Bosc, appreciate their more firm, yet tender flesh and their sweet-spiced flavor. Those who have not tried a Bosc, would most likely be surprised... and certainly be pleased that the brown skin hides a delicious, spicy and slightly firmer flesh. 
Available: August through April
