Fruit, sweetness and acidity
Separates flavour naming from actual fruit, sweetener and acid ingredients.
Flavour claim evidence
Support flavour and composition comparisons with ingredient or analytical evidence.
- Does the named fruit appear as juice, another fruit preparation, flavouring or an unspecified flavour claim? definition
- What juice content, sugar concentration or acidity measurements are available, and on what basis? measurement

What it is Filled
Chūhai is a Japanese category of alcoholic mixed drink derived from the shōchū highball, typically combining a distilled spirit, carbonated water and flavouring, with modern products also using vodka or other neutral spirits.
In scope
- Chūhai identity and its boundaries with neighbouring beverage categories
- Alcohol base, dilution, carbonation and flavour formulation
- Alcohol strength, serving quantity and declared nutritional composition
- Packaged and freshly prepared forms
- Storage condition, package integrity and readiness for service
Out of scope
- Production and classification of shōchū, vodka and other base spirits
- Cultivation and processing of fruit used as ingredients
- General cocktail and alcoholic beverage taxonomies
- Manufacturing equipment and packaging material engineering
- Individual medical suitability and diagnosis
- Licensing and retail operations beyond constraints applicable to the beverage
Why it exists Filled
Enable an agent to recognise chūhai, describe its formulation and serving state, and assess suitable handling and use without assuming that every product has the same alcohol base or composition.
Distinguishing features Filled
- Identify it as a formulated alcoholic drink associated with the chūhai category, rather than treating the name as a single chemical substance.
- Check the stated alcohol base and recipe; do not require shōchū solely because of the category name.
- Record carbonation and dilution to distinguish the served mixture from an undiluted base spirit or a flavour concentrate.
- Use the producer's or preparer's designation together with the formulation to assess boundaries with drinks sold as sours, highballs or other mixed drinks.
- Distinguish fruit juice, fruit-derived flavouring and other flavour ingredients; a fruit name alone does not establish juice content.
What robots and AI may and may not do Filled
Must not
- Sell, serve or promote it to people under the legal drinking age.
- Present sweet canned versions as low in alcohol when they are strong.
- Encourage heavy drinking or drinking before driving.
- Serve it to people who are visibly intoxicated.
Only with a human decision
- Serving alcohol at events the agent helps run.
May
- Describe chuhai, its history and styles, citing sources.

- Assess readiness for service using storage history, package integrity and opening state.
- Identify missing evidence behind fruit, sugar or category claims before relying on them.
Hazards and failure modes required Filled
- Alcohol consumption can impair judgment and coordination and increase accident risk.
- Sweet or fruit flavours can make alcohol strength difficult to judge by taste.
- Undeclared or overlooked ingredients can expose susceptible consumers to allergens.
- Damaged or overheated pressurized containers can leak or rupture.
Standards and interfaces required Filled
- The Liquor Tax Act, enacted by Japan's National Diet, governs liquor taxation and classification according to the beverage's formulation.
