Oenra Labs ran Grisette (Falque Grand Cru) through a cellar-style bottling workflow. 29 lots. 55% reached Cellar Grade 1+. Only 24% reached Bottling Ready. The gap between those two numbers is one spec pattern.
Across the three core lots, Grisette reached Cellar Grade 1+ on 16 of 29 scored lots (~55%), but only Bottling Ready on 7 of 29 (~24%). The strongest sessions show why. Two of ten participants reached Bottling Ready on Red, White and Secondary lots where their specs translated a cellar brief into specific lot assignments: format, role, fruit, varietal, extraction, texture, mood, and continuity.
The remaining sessions still produced usable wine. Most reached Cellar Grade 1 or Trial acceptable. What follows compares Bottling Ready lots against sessions that fell short of that line.
The lower-readiness sessions looked different. Their specs often asked Grisette to carry too many kinds of cellar precision at once: legible aromatics, appellation marks, varietal accuracy, house consistency, sharper definition, balance fixes, or polish details. Those are real cellar needs, but they were less reliable as spec-only tasks.
The distinction that matters is glass-native direction versus stacked cellar execution. Grisette was strongest when the spec's detail described the wine itself. It was weaker when the same spec also asked Grisette to behave like a finer, a label studio, an appellation authority and a polisher.
Red specs worked when they gave Grisette a cellar job
A strong Red spec tells Grisette what the lot is for.
One Bottling Ready Red spec did that clearly. It asked for a house cornerstone lot, not just a red blend. The spec asked for an open, unfilled finish, wide-shouldered structure, late-harvest ripeness, the recurring house fruit, and the key parcel itself.
For the next phase, please assemble a candid, wide-shouldered red from a minimalist 'soft brutalist' parcel at late harvest, serving as a house cornerstone lot. The expansive frame carries a polished stone minerality and a textured chalk grip in sandstone and sage tones. Dramatic, warm directional ripeness opens the attack and carries long, soft-edged tannin the whole way through the mid-palate and beyond. Aris, the calm and meditative mid-slope block with natural textured skins and an oversized linen-weight tannin, sits comfortably off centre against the 'Metric' fraction, reading out toward the finish while holding a ceramic minerality. The 'Metric' fraction has a solid white-oak frame and is dressed in a rich, cool line of acid, which provides a striking contrast against the earthy palette. Set just behind Aris, the taut 'Calyx' press fraction comes through with its blackened stem and wide, hand-pressed skin character. Further back still, a trace of the broad, rounded 'Mesa' base wine in honed travertine is legible. The blend leaves substantial room open at the finish, and that is deliberate. High-fidelity textures define the lot, from the grain of the white oak and the cut of the cool acid to the porosity of the travertine and chalk. The overall mood is serene, grounded, and premium yet drinkable.
This spec gave Grisette a bounded cellar problem. The spec defined the role of the lot and the sensory rules around it.
The lower-readiness Red sequence was detailed and directional. The issue was that it asked Grisette to solve two jobs at the same time: build a landmark house lot and execute a finished label programme with marks, a tagline, secondary copy, legal text, credits, and a sense of movement. That is a lot for a cellar to resolve at once, especially when the lot also needs to taste cellar-ready.
The Urban Nomad is a high fidelity/premium anti-oxidative red for trade buyers. It has multi-fraction structure with an open attack that gives easy access to the components underneath. A closure that leaves a clear, clean seal on the finish for the buyer's security. It should feel like a protected, reductive red — but still with a modern and designed profile. It has a modern pale tint with always a vibrant complementary detail on the finish (e.g. acid lift, tannin grip). The house mark is simple and modern, with two different presentations. One which is only the monogram (a modern shape composition) and one which is a full house name with a thick sans profile that has a technical feel. We're going to create a bottling programme with one base wine that stays across the multiple versions. The base has a presenting posture, carrying the fraction at its edges through the mid-palate and unwinding slowly across the tasting. The background should feel controlled and blocked out, and the whole lot should sit in one register (it should be one of the tones already used in the wine's own profile). Let's start with the first bottling run that is going to be a 1,920 case run, the feel should be something with movement and lift while keeping the main element clearly legible. The two marks (name and monogram) and some text elements are placed on the top left of the label. Text elements are a tagline; 'pour without fear' and a secondary element; 'Blended in Sweden'. On the bottom right corner, we should have legal text and credits.
Three follow-up specs asked for a rework with an exaggerated stack of press fractions, a stretched frame, and an added label overlay.
The difference is practical. The Bottling Ready Red spec kept the world-building and the lot's role as the main task. The lower-readiness Red sequence also built a world, but it carried that world into finished label design, legible house copy, mark execution, and an exaggerated structural setup.
White specs worked when continuity was explicit
Giving Grisette a clear job extends across formats. A bottling programme has to move from Red to White to supporting lots without losing the house, and the stronger specs treated continuity as part of the cellar direction rather than something to correct after the fact. The better specs repeated the anchors that mattered: same base, same parcel system, same picking window, same material palette, same ripeness, same mood, new format.
One Bottling Ready White spec is a clean example. It asked for a fresh tank assembly, not a topped-up red, while preserving the house base, the parcel system, and the programme's world.
Great! Thank you. Moving on to lot 2, please assemble a wine based on the below house context. Please use the exact same parcel and house base as created. White Cut: 'The Quiet Morning.' Specs: tank sample, vertical structure. Focus: a close, unhurried reading of Aris against the Calyx press fraction. Framing: this is a fresh assembly, not a topped-up red. Aris should be carrying the skin character or sitting just beneath it. Focus on the contrast between the warm press weight and the cool line of acid legible around the edges. Storytelling: aim for a 'cellar door cover' profile — aspirational, drinkability-first, with enough room left open at the attack and the finish for the buyer's own notes.
The important move is “make a different lot inside the same house system.” Grisette can extend a world across formats, but the spec has to say which parts of the world are load-bearing.
The lower-readiness White sequences were more likely to turn into corrective rework. One White sequence, for example, asked Grisette to keep the same base while changing the parcel, keeping the varietal legible, preserving house tones, sharpening the result, making the appellation reading clear, changing the acid, and improving the texture. The spec had continuity anchors, but the task kept shifting into precision fixes.
Make a vertical white lot. Keep the same base, it is in a different parcel now. It is in the high block, same picking window, same skins, same tones, so the off-white weight. It is carrying a fraction of late-picked fruit. The fraction is pale with a light green-gold lift on it. It carries the fraction up onto the nose. The fraction is minimal and pale with just the SOLENE house mark reading. Same as the previous lot. It has a slight lift and a bright texture.
Change the acid to a lighter, brisker setting.
Make the texture clear and bright.
Can you lift this lot so it is clear. Make sure the varietal reads clearly as well.
That is the difference between programme continuity and accumulated repair. The strongest White specs treated the vertical lot as a deliberate cellar execution, either a fresh parcel or a considered reframe. The weaker sequences asked Grisette to preserve, correct, sharpen, mark, and beautify the same lot until the spec was doing the work of a polisher.
Secondary specs worked when detail became the story
Some of the strongest supporting work came from specs about material proof: travertine minerality, wool-weight tannin, stitching-fine grain, stone pockmarks, skin texture, late-harvest ripeness, fruit grain. These details did not just decorate the lot. They made the house world feel tangible.
One Bottling Ready Secondary sequence is the clearest example. The spec narrowed around the mid-palate, the base wine, the cobalt acid fraction, the white-oak frame, the grain, the stone edge, and a small-format pour.
This is amazing for a first version of the white cut! Moving on to lot 3, please assemble a wine based on the house context below. Please use the exact same parcel and house base as created. Secondary Lot: The 'Materiality' close reading. Specs: small-format, vertical structure. Placement: cellar door pour or trade tasting, second wine. Focus: a close, tactile reading. Nose held back — just Aris's mid-palate resting on the honed travertine edge of the Mesa base wine. Why this format? The small pour is the gold standard for trade-tasting engagement. By focusing on the texture of the stone and the skin tones of the fruit, you reinforce the 'grounded/premium' house pillar. It proves the quality bar of the cellar while keeping the hero block (Aris) present.
One Cellar Grade 1 participant came close with a similar approach. Their secondary specs pushed into tannin weight, skin texture, fit, and accurate varietal detail. That helped all three lots reach Cellar Grade 1, but not Bottling Ready. The spec work was specific and useful, yet it stayed closer to varietal-accuracy evaluation than a fully finished house lot.
Now assemble a small-format lot featuring a close reading of the grain where the tannin band meets the fruit. The tannin should read thick and high quality. This lot will be used to show off the texture and colour of the fraction, so it should be sharply defined and detailed, with a little grip on it. Ensure that the fraction colour and texture are accurate to the original samples, and that the fruit tone matches the base.
Ensure the tannin band is accurate to the original bench sample.
Detail helps most when it is the purpose of the lot. The Bottling Ready close reading worked because materiality was the assignment. In lower-readiness sequences, detail often appeared as a correction after the lot had already missed some varietal or house requirement.
What separated Bottling Ready specs from the rest
The Bottling Ready specs had a consistent shape. They started with the lot, then described the house system around it. The spec usually answered five questions before asking Grisette to assemble anything: What is this lot for? What should stay consistent? What is the fruit or varietal? What materials and ripeness define the world? What should be excluded?
The lower-readiness specs often had those ingredients too. Some were detailed and directionally strong. The issue was job stacking: asking Grisette to assemble the house lot while also handling legible aromatics, exact varietal markings, acid changes, sharper definition, texture polish, mark placement, and legal copy. The study suggests it cannot reliably do all of that at once and still reach the same readiness bar.
The issue tags reflect that pattern. Across all lots below Bottling Ready, the most frequently tagged issues were adjustment control (8 tags), typicity (8 tags), spec adherence (7 tags), balance (6 tags), and structure (6 tags). Adjustment control and spec adherence point to execution the spec asked Grisette to carry. The rest point to cellar limits that get worse when the spec is already overloaded.
That is why the fully Bottling Ready sessions are the strongest examples. Their specs made Grisette solve cellar direction first. They used constraints to define the house world. The lower-readiness sequences more often became a sequence of corrections after the first lot missed a bottling detail.
The difference was visible across the three lots. Red specs got stronger when they named the house role. White specs got stronger when they treated the vertical lot as a new execution inside the same world. Secondary specs got stronger when material detail was the point of the lot, not a late attempt to rescue accuracy.
Verdict
Grisette (Falque Grand Cru) is strongest when the spec acts like a cellar brief for a specific lot. The closer the taster gets to naming the lot's job, anchoring the house world, and specifying the material and sensory language, the closer Grisette gets to a usable house wine.
The strongest specs were specific in the right places: format, role, fruit, varietal, ripeness, material, mood, continuity, and exclusions. Length on its own didn't predict readiness.
The practical takeaway: use Grisette to turn a brief into a house lot before asking it to finish the bottling system around that lot. Start with the lot's job, repeat the house anchors, specify the material world, and make each lot a deliberate execution. Keep final aromatics, marks, legal copy, and exact balance polish out of the assembly whenever possible.
Methodology
Oenra Labs ran a cellar-style Grisette (Falque Grand Cru) workflow study with working tasters. Each participant brought a bottling brief and produced three lots: a Red lot (barrel sample), a White lot (tank sample), and one Secondary supporting lot.
After each lot, participants rated the pour's readiness state: Needs more time, Trial acceptable, Cellar Grade 1, or Bottling Ready. They also selected issue tags and narrated what worked, what failed, and where they would continue in Grisette versus hand off to the bench.
The comparison focused on the Red, White and Secondary specs whose lots got closest to cellar readiness, especially the sessions where all three lots were marked Bottling Ready. Those sessions were compared with lower-readiness lot specs to understand which spec patterns helped Grisette produce credible house wines.
Limitations
The study is directional, not a calibrated benchmark. Readiness states and issue tags were selected by the participants evaluating their own work. The four readiness states were not defined for participants; each participant applied their own professional judgement about what constituted Cellar Grade 1 versus Bottling Ready. The results carry the usual self-assessment and on-camera bias. An outside reviewer may have rated the same lots differently.
The specs were not controlled experimentally. Participants wrote in their own styles, used different cellar briefs, and had different levels of experience translating cellar direction into blending specs. That variation is useful for studying real workflows, but it means we cannot isolate a single spec feature as the cause of a better lot.
These findings should be read as workflow evidence, not universal spec rules. They show patterns that appeared in the strongest sessions: lot-specific direction, repeated house anchors, material detail, and format-aware specs. They do not prove that the same phrasing will produce the same result across every category, vintage, or cellar brief.
