The Cocoa Crisis: Why Cacao Shortages Are Forcing Innovation in Chocolate Production
New Zealand's love affair with chocolate is no secret, with local favourite Whittaker's blocks flying off shelves despite soaring prices. But behind the indulgence lies a global crisis threatening the very bean that defines chocolate: cacao. Recent research from Rabobank New Zealand highlights how supply disruptions and climate challenges are pushing 'big chocolate' towards cacao-free alternatives, particularly lab-grown and plant-fermented options. Cacao prices skyrocketed to USD 11,900 per metric tonne in late 2024—over four times the historical average—due to droughts, diseases like swollen shoot virus, and erratic weather in West Africa, which supplies over 60% of global output. Even as prices eased by late 2025 to about double 2023 levels, the volatility persists, with projections suggesting up to 50% of current growing areas could become unsuitable by 2050 without major adaptations.
In New Zealand, an import-dependent market, this has translated to real pain at checkout. Average 250g blocks now cost around $6.89, edging towards luxury territory, with Whittaker's implementing multiple price hikes in 2025 alone. Rabobank analyst Paul Joules notes, “These high prices have been felt in consumers’ hip pockets, coming through in increased chocolate prices.” This report, titled 'Beyond the Bean', signals a shift from resilience strategies like hedging to outright innovation in cocoa-free pathways.
Understanding Lab-Grown Chocolate: A Bioreactor Revolution
Lab-grown, or cell-cultured, chocolate represents the most ambitious cacao-free alternative. It involves extracting plant cells from cacao trees and culturing them in bioreactors with nutrients, mimicking the natural 'matrix' of cocoa powder and butter without farming. This precision biotech approach promises identical composition to traditional cocoa, potentially enabling full chocolate bars rather than just compounds.
The process starts with cell sampling, followed by proliferation in controlled environments—temperature, pH, and sugars optimised for growth. Early pilots show promise, but scalability remains a hurdle. Joules describes it as “the only cocoa-free technology that offers a theoretical route to chocolate ‘bar-grade’ sensory experience,” yet it's “still in the pilot stage” with challenges in cost, regulation, and untested consumer acceptance. Globally, companies like California Cultured and Puratos are advancing this, partnering with majors like Barry Callebaut.
In New Zealand, while no direct lab-grown chocolate projects dominate headlines, the food biotech scene is ripe. Universities like Massey and the University of Auckland lead in cell agriculture, with Riddet Institute at Massey exploring microbial fats akin to cocoa butter. These efforts align with NZ's precision fermentation approvals, positioning local researchers at the forefront.
Plant-Fermented Chocolate: Scalable and Near-Term Solutions
Precision fermentation, the star of Rabobank's analysis, uses microbes like yeast or bacteria to convert plant inputs—oats, sunflower seeds, carob, fava beans, barley, or grape seeds—into chocolate-like fats, powders, and flavours. Unlike traditional fermentation (e.g., beer), this is engineered: genes programmed into microbes produce specific molecules, fermented in vats, then purified.
- Step 1: Select feedstock (e.g., sunflower seeds for sustainability).
- Step 2: Engineer microbes via CRISPR for cocoa flavanols, theobromine.
- Step 3: Ferment in bioreactors (days/weeks).
- Step 4: Extract, refine into cocoa equivalents.
Planet A Foods' ChoViva, from fermented oats/yeast, exemplifies this—already in European bakery fillings. Joules praises its scalability for “mainstream snacks and bakery formats” but notes flavour gaps: “a challenge replicating the rich, complex flavour of traditional chocolate, especially for premium products.”
NZ's fermentation prowess shines through Daisy Lab's EPA approval and projects at AgResearch's Bioeconomy Institute, converting pine residues to proteins—tech transferable to chocolate fats. Explore research jobs in NZ's burgeoning food biotech sector.
Upcycling and Other Innovations: Maximising Sustainability
Beyond lab and fermentation, upcycling repurposes cocoa by-products (shells, pulp) or others like brewers' spent grain into functional ingredients. This low-tech win suits high-volume compounds, reducing waste while cutting costs. Rabobank sees hybrids emerging: fermented fats + upcycled fibres for texture.
NZ context amplifies this: With strong agribusiness, universities like Lincoln focus on bioeconomy, turning forestry waste via fermentation—parallels to chocolate innovation. These methods address deforestation links, as EU regs tighten on cocoa imports.

Challenges on the Path to Cacao-Free Chocolate
Taste reigns supreme. Fermented options deliver 'chocolatey' profiles but lack cacao's depth—bitter notes, melt, mouthfeel. Lab-grown holds bar potential but faces 5-10 year commercialisation. Costs: Fermentation competitive now, lab-grown 10x pricier. Regulations: Novel foods need approval (NZ EPA proactive). Consumer trust: 38% UK open, but Kiwis prize authenticity—Whittaker's premium ethos may resist.
| Alternative | Pros | Cons |
|---|---|---|
| Lab-Grown | Identical composition, sustainable | Pilot-scale, high cost |
| Fermentation | Scalable, near-term | Flavour gap |
| Upcycling | Cheap, waste reduction | Compound-only |
New Zealand's Chocolate Landscape: From Imports to Innovation
NZ consumes ~12kg/person/year, mostly imported. Whittaker's, 50% market, sources Ghana beans, hiking prices 50c/block in late 2025 amid shortages. Rabobank predicts alternatives first in compounds (biscuits, ice cream), preserving pure bars. Local players eye fermentation for cost stability.RNZ on NZ chocolate future
