The Taggiasca, Casalivo, Allegra, and Leccino olives for this very small-batch oil are grown, not in Napa, but on the company's 16-acre ranch in Suisun Valley -- not to mention milled by a quality-conscious Jesuit monk. We tapped the slim bottle last night, on the eve of its official release, and dabbed away at a lime-green pool with salt-speckled bread, and later, radish slices. The helpful card that came with the bottle suggested a white bean purée (we already have cannellini soaking). The organic, cold-pressed oil -- spicy, herbaceous, and wonderfully pungent -- can be yours for $24, or $260, if you brush enough crostini to warrant stowing away a whole case. As it turns out, the uncle rolls a little deeper than we thought.
You can score your own directly from Katz, or -- in a day or two -- from Bi-Rite in the Mission (3639 18th St. at Guerrero). In the East Bay, both Pasta Shop locations (1786 Fourth St. at Hearst, Berkeley; Rockridge Market Hall, 5655 College at Shafter, Oakland) already have a supply.
