A friend recently commented favorably on a single-barrel malt whiskey that was not only aged in oak barrels, but also was aged on cherry and apple wood chips. That got me wondering - I've been using oak chips in some of my brews for several years. Can anyone tell me what different characteristics using cherry, apple, pecan, or other wood would impart to a beer? Not for smoking - for adding in the secondary or the keg.
TIA
