Altbier 7B: the amber ale that acts like a lager

You already own Märzen and Vienna. Altbier is the third leg of ID 60 (Altbier · Märzen · Vienna Lager). Learn it and you can write that whole triplet from memory.

Aim. In ID 60, two of the three are amber lagers (Märzen, Vienna). Altbier is the odd one: an amber ale. The ferment is the tell, and the bitterness is the split. Nail those two and the triplet pivot writes itself.

Compress: the one idea

Altbier is Düsseldorf's ale that behaves like a lager: top-fermented (an ale, "alt" = the old pre-lager way), then cold-conditioned so it drinks clean and smooth. Unlike its amber-lager cousins, hop bitterness asserts itself: a firm, dry, bready-nutty amber where malt and a real bitterness are in balance. Compressed from BJCP 2021 Guidelines, 7B Overall Impression + Style Comparison.

The process paradox is the whole style: ale yeast, lager treatment. Do NOT write "bottom-fermented" – it is top-fermented, then lagered.

The two traps (both were live errors we killed today)

Malt stops at bready/nutty. Baked bread, nutty toasted crust – and that is it. No roast. No chocolate. The Guidelines say the malt "should not have darker roasted or chocolate notes." If you are tempted to write "chocolate", you are wrong.
Head is off-white, not tan. Colour is amber to deep copper, stopping short of brown (bronze-orange most common), with a thick, creamy, long-lasting off-white head.

Sensory, IQ-method

Sense	Write it like this
Aroma	Moderate to moderately-high malt: baked bread / nutty crust. No roast or chocolate. Moderate to low hop (spicy/peppery/floral), complements not dominates. Very clean. Low esters optional.
Appearance	Amber to deep copper, short of brown; bronze-orange most common. Brilliant clarity. Thick, creamy, long-lasting off-white head.
Flavor	Assertive medium-high bitterness balancing rich malt. Medium-dry to dry finish, grainy bitter malty-rich aftertaste, long-lasting (sometimes nutty/bittersweet). No roast, no harshness. Clean; light dark-fruit esters may show.
Mouthfeel	Medium body. Smooth. Medium to medium-high carbonation. Astringency low to none.

In triplet 60, the one thing that separates Altbier from Märzen and Vienna is...

Say it out loud in full sentences before you reveal. Half-answers count as misses.

It is an ale, and hop bitterness asserts – drier and more bitter

Ale ferment + assertive bitterness and a firm dry finish. Malt unites the trio; bitterness/dryness cuts Altbier off.

The official compare lines (verbatim)

vs Vienna Lager (7A): "Drier, richer, and more bitter than a Vienna Lager."
vs International Amber Lager: "More bitter and malty."
vs California Common: "Somewhat similar... both in production technique and finished flavor and color, though not in ingredients."
vs Dunkles Bock: "Less alcohol, less malty richness, and more bitterness."

Ingredients & process (the 40% comparison axis)

Sensory is 50%, but the compare/contrast block is 40%, and the Guidelines name ingredients and fermentation/process as differentiators. For ID 60 they line up exactly with the one idea:

Axis	Altbier 7B	Märzen 6A / Vienna 7A
Malt	German base (Pils, sometimes Munich) + small crystal/chocolate/black for colour; may include wheat	Märzen: Munich-forward. Vienna: Vienna malt (signature)
Hops	Spalt (or German/Czech), enough for the assertive bitterness	continental / noble, restrained
Yeast	Clean, highly attenuative ALE yeast	both LAGER yeast ← the split
Mash	Step mash traditional	Märzen: decoction. Vienna: Guidelines do not specify
Ferment	Cool ale temps, then cold-conditioned	bottom-fermented, lagered

All from BJCP 2021 Guidelines (7B / 6A / 7A Characteristic Ingredients + Tags). Vienna's mash is left blank on purpose: the Guidelines do not state it, so do not claim decoction for Vienna.

Commercial examples: all seven

Name one or two. The two in highlight are the Düsseldorf benchmarks and the best tasting anchors – Uerige is the classic Altstadt reference; Diebels is the widely-available one in Europe.

#	Guidelines 2021, 7B
1	Bolten Alt
2	Diebels Alt
3	Füchschen Alt
4	Original Schlüssel Alt
5	Schlösser Alt
6	Schumacher Alt
7	Uerige Altbier (Düsseldorf classic)

Feynman teach-back

Cover the screen. Teach me Altbier in three sentences: (1) the process paradox, (2) the malt and colour (with the two traps), (3) what splits it from Märzen and Vienna in ID 60. Then reveal.

Altbier is Düsseldorf's amber ale that behaves like a lager: top-fermented ("alt" = the old, pre-lager method) but cold-conditioned, so it finishes clean and smooth. The malt is bready and nutty with a deep-copper, short-of-brown colour and an off-white head, and it carries no roast or chocolate. What sets it apart in triplet 60 is the ferment and the balance: it is an ale, and its assertive hop bitterness and firm, dry finish make it drier, richer, and more bitter than Vienna Lager, while Märzen and Vienna stay malt-balanced lagers.

Run: today's scoring artifact.

"Altbier = amber ALE that drinks like a lager (top-fermented, then cold-conditioned). Bready/nutty malt, NO roast/chocolate, off-white head. The split in ID 60: it is the bitter, dry one – drier, richer, more bitter than Vienna; malt unites the trio, bitterness cuts Altbier off."

Next: write the whole triplet. You now own all three of ID 60 (Altbier · Märzen · Vienna Lager). The drill is a full S0 answer on the clock: open with the pivot (what unites the trio = clean amber, bready/toasty German malt; what splits them = intensity for Märzen/Vienna, ferment + bitterness for Altbier), then IQ-method sensory prose for each. No parameters table.
