The 2015 Cabernet Sauvignon Walla Walla is deep and brooding, unwinding in the glass with aromas of ripe berries and plums that mingle with hints of pencil shavings and creamy new oak. On the palate, it's medium to full-bodied, with notable power and concentration, but it's all wrapped up in a tight corset of very firm, hard and aggressively extracted tannins that make me question the wine's ultimate balance. The mouth-puckering finish only confirmed my fears.
