American Brown Ale 4.5 º

Round Corner Brewing

This session-strength American Brown Ale presents a nuanced interplay between classic dark malts and modern English hop innovation. Inspired by the brewery's Mackinaw, Mack Opus features the experimental hop variety CF-182, also known as Opus, which contributes a unique floral and herbal dimension to the sensory profile. The palate is defined by rich notes of chocolate and toasted nuts, supported by a gentle caramel sweetness. Despite its modest alcohol content, the beer maintains a medium-bodied presence with a clean, balanced finish. The interplay of roasted malt depth and the distinctive Herefordshire-grown Opus hops creates an approachable yet complex drinking experience that honors its American lineage while embracing British terroir.

Appearance. Deep mahogany to dark brown (approximately 25-30 SRM) with ruby highlights. It displays excellent clarity and is topped by a moderate, persistent off-white to light tan head that leaves delicate lacing on the glass.

Aroma. Moderate intensity with a rich malty core featuring notes of milk chocolate, toasted bread, and roasted hazelnuts. The hop character is distinctively floral and slightly earthy due to the Opus hops, providing a subtle counterpoint to the malty-sweet aromatics. Low fruity esters are present, though the primary focus remains on the marriage of roasted grain and fresh English hops.

Taste. Initial flavors of caramel and bittersweet chocolate lead into a toasted malt complexity. The bitterness is medium-high but well-integrated, providing a firm structure without being aggressive. Hop flavors from the CF-182 variety offer hints of herbal tea and wild meadows. The finish is medium-dry, leaving a lingering aftertaste of cocoa and a clean, resinous hop snap.

Mouthfeel. Medium body with a smooth, slightly creamy texture. Carbonation is moderate to moderately high, enhancing the beer's sessionability. At 4.5% ABV, there is no perceptible alcohol warmth, resulting in a refreshing and light-on-the-palate experience.
