Meet Macchiato, an imperial stout brewed in collaboration with Acton-based George Howell Coffee. This 10.5% beauty is loaded with chocolate malts, lactose, and oh so many cups of Joe! George Howell was kind enough to provide us with their Alchemy blend, featuring beans from Costa Rica, Brazil, Guatemala, and Ethiopia, which provide notes of chocolate and almond. Also present are palate pleasers like malty milk chocolate and creamy caramel. This imperial stout will have baristas scratching their chins.
