Tasting Notes

AI-generated sensory profile for Rocker 12

◎ Appearance

Rocker 12 presents a brilliant golden hue with the characteristic haze of an unfiltered lager. The cloud is fine and even, allowing light to pass through while maintaining opacity. A creamy head forms readily and clings to the glass with persistent lacing, characteristic of proper carbonation and protein content.

◌ Aroma

The nose is dominated by clean, grassy Žatec character with herbal and slightly spicy notes from Herkules. The aroma hops Most and Harmonie add subtle floral and citrus undertones beneath a soft bready foundation. The overall impression is fresh and straightforward, with no sulfur or yeast-driven esters—a mark of clean lager fermentation.

◐ Taste

The palate opens clean and crisp, with a light malt body that allows bitter character to come forward immediately. Bitterness dominates throughout, conveying earthy and herbal notes from the hop bill, while the malt provides a gentle bready sweetness in the mid-palate that prevents harshness. The finish is dry and hoppy, leaving little residual sweetness.
