Tap at Preserve in Winters, CA. Preserve board said ESB, but brewery board says ASA. Pours very hazy amber with a beige head. Aroma seems citrus/pine. Med body. Flavor seems pine/citrus; malt is light. Thinking ESB it was more bitter than expected, but it does have something like that ESB softness. Might be a hoppy ESB, if from cask. As its, ASA is more like it. Or call in American ESB. :)
