Description

Clean yet robust and complex aroma of rich malt, noble hops and restrained fruity esters. The malt character reflects German base malt varieties. The hop aroma may vary from moderate to very low, and can have a peppery, floral or perfumy character associated with noble hops. No diacetyl. Appearance: Light amber to orange-bronze to deep copper colour, yet stopping short of brown. Brilliant clarity (may be filtered). Thick, creamy, long-lasting off-white head. Flavour: Assertive hop bitterness well balanced by a sturdy yet clean and crisp malt character. The malt presence is moderated by moderately-high to high attenuation, but considerable rich and complex malt flavours remain. Some fruity esters may survive the lagering period. A long-lasting, medium-dry to dry, bittersweet or nutty finish reflects both the hop bitterness and malt complexity. Noble hop flavour can be moderate to low. No roasted malt flavours or harshness. No diacetyl. Some yeast strains may impart a slight sulfury character. A light minerally character is also sometimes present in the finish, but is not required. The apparent bitterness level is sometimes masked by the high malt character; the bitterness can seem as low as moderate if the finish is not very dry. Mouthfeel: Medium-bodied. Smooth. Medium to medium-high carbonation. Astringency low to none. Despite being very full of flavour, is light bodied enough to be consumed as a session beer in its home brewpubs in Düsseldorf.

Examples: Altstadt brewpubs: Zum Uerige, Im Füchschen, Schumacher, Zum Schlüssel; other examples: Diebels Alt, Schlösser Alt, Frankenheim Alt
