Cognitive Bias Bump Matrix

Pre-Test Expectation vs. Double-Blind Reality

Before tasting, panellists ranked all 10 colas based on brand reputation. In unbranded double-blind evaluation, participants were unaware of product identity, code mappings, or serving order, evaluating samples independently without discussion.

Just-About-Right (JAR) Penalty Engine

Sensory Penalty Analysis & Formulation Faults

In sensory science, Mean Drop shows the observed mean liking difference in overall liking when sweetness or fizz deviates from “Just Right”.

← LIKING PENALTY (POINTS DROPPED)JAR 3.0 EQUILIBRIUM (DATUM: 0.0)HEDONIC SURPLUS (POINTS GAINED) →
Sweetness: Too Low (Levels 1–2)-1.65 pts drop (40% of evaluations)
-1.65 pts
Critical insight: Within this panel's evaluations, under-sweetened responses were associated with a 3.9× larger mean liking drop than over-sweetened responses.
Sweetness: Too High (Levels 4–5)-0.42 pts drop (22% of evaluations)
-0.42 pts

★ The “Super-JAR” Effect: Within this dataset, evaluations rating a cola as “too fizzy” recorded a mean liking of 6.18/9, notably higher than the 4.06/9 recorded for “just right” fizz. This indicates an observed association where panellists favoured samples with elevated carbonation.

Budget Cola Swaps: The Verdict

Can budget supermarket colas ($0.87 to $1.15/L) realistically replace a $3.04 to $3.60/L Coca-Cola or Pepsi habit? Here is what the empirical sensory and chemical data revealed.

Budget Colas Evaluated · Blind Panel Data
🥇 THE GIANT KILLER · $1.15 / L

LA Ice & LA Maxi Ice (5.0 / 9)

Beat Coca-Cola Zero Sugar in blind tasting.

Manufactured by Refresco in Victoria, this $2.30 / 2 L bottle achieved Rank 2 and 3 on the panel, outscoring Coca-Cola Zero Sugar (4.8/9). It also delivered +47.8 g net mass surplus (~+48 mL at ~1.00 g/mL density).

⚡ CULT POLARISER · $0.92 / L

Coles Que Cola (3.6 / 9)

Low carbonation, but one panellist's #1 favourite.

All 5/5 testers found Que Cola too flat, and 4/5 found it under-sweetened. Yet Tester 01 picked it as their single favourite cola of the entire test. Mild, divisive, but very cheap ($1.15 / 1.25 L = $0.92/L).

⚠️ DISAPPOINTING · $0.87 / L

ALDI Regal No Sugar (3.2 / 9)

Lacks acidic bite with 30× the sodium of Diet Coke.

Despite ALDI's strong reputation for private label products, Regal ranked 9th of 10 ($1.09 / 1.25 L = $0.87/L). Laboratory testing revealed an unusually high pH of 4.15 (lacking crisp acid bite) and 30 mg sodium per 100 mL.

❌ BOTTOM OF BENCHMARK · $0.92 / L

Woolworths Cola Zero (3.0 / 9)

Rated lowest on panel liking with harsh aftertaste.

Finished dead last (Rank 10 of 10) despite its competitive $1.15 / 1.25 L ($0.92/L) price point. 0/5 testers rated sweetness just right, 3/5 rated it flat, and panellists cited medicinal aftertaste. The only cola using preservative 202 (potassium sorbate).

Preference Filter & Cola Finder

Filter products based on taste preference criteria (sweetness, carbonation, caffeine status) calculated against the benchmark dataset.

Primary evaluation priority

Weighted compatibility score (0–100%): 70% primary metric rating + 15% sweetness alignment + 15% carbonation alignment. Panel baseline: 3 = just-about-right.

How matching works

Sensory JAR Mapping vs Sugar Grams: The sweetness and carbonation sliders map to the panel's 1–5 Just-About-Right (JAR) distributions, where 3.0 represents “just right” balance. Because all 10 products contain 0.0 g sugar, the slider calibrates against perceived sensory sweetness and fizz intensity rather than chemical sucrose or intense sweetener grams.

Caffeine as a Hard Exclusion Filter: The caffeine option acts as a deterministic hard filter rather than a weighted factor. Selecting “100% Caffeine-Free only” removes all caffeinated options immediately from the candidate pool prior to scoring.

Compatibility Formula: Candidate colas are scored out of 100%: 70% primary sensory liking (normalised from 1–9) + 15% sweetness JAR proximity + 15% carbonation JAR proximity.

Physical Packaging & Gravimetric Mass Audit

Australian Packaging Forensics: Gravimetric Liquid Mass & Bottle Tare Audit

Precision scales recorded unopened bottle gross mass, with verified dry packaging tare deducted to establish net liquid mass in grams. Zero-sugar colas approximate water density (~1.00 g/mL), meaning net liquid mass closely approximates fluid volume in millilitres without claiming direct pycnometric volume measurement. In this single-bottle sample, 8 of 10 colas deliver surplus mass (+1 g to +47.8 g). Under Australia's National Trade Measurement Regulations, the Average Quantity System (AQS) establishes a Tolerable Negative Error (TNE) reference threshold (19 mL for 1.25 L and 30 mL for 2.0 L) for commercial packaging runs. While formal AQS compliance applies across entire production lots rather than single retail bottles, all 10 measured samples fell comfortably within this reference tolerance window.

Pepsi Max

+0.34% Mass Surplus

Nominal capacity declared on-pack is 1.25 L (1250 mL). Precision scale reading of the full unopened bottle was 1295 g. Deducting the verified empty PET bottle tare weight of 40.7 g (Unique Pepsi Max) establishes that the bottle contained 1,254.3 g of net liquid mass (+4.3 g vs nominal 1:1 mass equivalent, corresponding to an inferred volume of ~1,254.3 mL at ~1.00 g/mL density).

AQS Regulatory Reference & Packaging Methodology: Australia's Average Quantity System (AQS) governs commercial packaging across production batches under the National Measurement Act, specifying a Tolerable Negative Error (TNE) reference threshold of 19 mL for 1.25 L and 30 mL for 2.0 L packages. This single-bottle experiment provides exploratory product-level data rather than an official batch-compliance audit. For regulatory context, every measured sample sat well inside the reference deficiency boundary, led by ALDI Regal (+29.1 g net mass surplus) and Refresco 2.0 L bottles (+47.8 g net mass surplus; ~1.00 g/mL density approximation).

TESTING PROTOCOL & DATA SOURCES

Methodology & Verification

CW
v2.0
01

Five-Tester Panel Scope

Five adult participants evaluated 10 zero-sugar colas in unbranded sample cups. Findings reflect this specific panel rather than an Australian population study.

02

Double-Blind Serving Protocol

Samples were identified by randomised 3-digit reference codes, chilled to uniform temperature, and presented in identical glassware under controlled test conditions. Participants were unaware of product identity, the code-to-product mapping and upcoming serving order, and evaluated samples independently without discussing ratings with one another. Sample preparation and serving personnel were also blinded to code mappings during evaluation sessions.

03

Hedonic & Just-About-Right Scales

Overall, flavour, and aftertaste liking were recorded on a standard 1–9 hedonic scale. Sweetness and carbonation were evaluated on 1–5 Just-About-Right (JAR) scales.

04

Verified Packaging Data

Ingredients, nutritional values, volume measurements, and barcode specifications were audited from commercially purchased Australian retail bottles.

05

Calibrated pH & Acidity Analysis

Acidity levels (pH) were recorded using calibrated lab probes with triplicate readings averaged across samples under standard laboratory conditions.

06

Standardised Descriptors

Post-sip aftertaste notes were recorded using multi-select category checkboxes to map perceived sensory attributes across formulations.

Retailer note (ALDI Regal). Tested bottle data reflects the physical September 2026 sample (aspartame 951, Ace-K 950, and sodium benzoate 211). ALDI's current online listing describes a formulation with no artificial sweeteners or added preservatives, indicating that current retail stock or online product information may differ from the tested bottle.
