Lustau Amontillado Los Arcos Sherry

Lustau Amontillado Los Arcos, dry Jeres-Xeres sherry, solera familiar. 18.5 % abv. Tasted at cool room temp. Deep rose brown and coating legs in the glass. Nose is nutty, cherry and grapes, red wine. In the mouth, big rush of sweet and sour grape wine, earthy compost, minerals, and light oak. Finish is quick, the sour turning mineral dry with a light earthy sweetness left on the tongue. Again, I'm no expert on sherry--use them mainly for mixing cocktail and cooking. This one is quite a bit more burly and forceful than the Lustau Oloroso Don Nuno I tried recently (at 20% abv). Due to the solera aging on this one? Don't know enough. But I do know I appreciate that more forceful flavor in cocktails and cooking, if not casual sipping.
