The Squeaky Wheel is a brooding, spirit-forward sipper that layers smoke and bitterness with unexpected warmth. Mezcal's ashy backbone meets Campari's bracing citrus peel notes, while coffee liqueur and a touch of amaretto soften the edges with roasted depth and subtle marzipan sweetness. The result is dark, complex, and vaguely reminiscent of a Negroni that wandered into a late-night espresso bar.
