01 Feb 2026 Dry oat milk ‘slices’ – innovation in plant-based beverages
The plant-based milk category — long dominated by liquid formats such as oat, almond and soy milk — is seeing a novel format emerge…
Hello dry oat milk slices, an innovation that reframes how plant milks are produced, packaged, distributed and consumed, with implications for sustainability, cost and category growth.
The dry slice concept — currently being commercialised by Milkadamia using macadamias (a US company operating in Australia) — consists of thin, dehydrated sheets of milk that are hydrated by the end-user by adding water and blending.
This shift moves the hydration step from the production line to the point of consumption, offering potential efficiency gains across the value chain.
Redefining sustainability and supply-chain efficiency
One of the most compelling aspects of plant milk slices is their sustainability proposition. According to reports on their launch, the flat, dry format uses around 85 % less packaging material and weight compared with conventional oat milk cartons such as Tetra Paks.
Lightweight, low-volume formats reduce costs and emissions across transportation, warehousing and retail logistics.
The potential to cut packaging waste dramatically responds directly to concerns around plant-based milk cartons, many of which are technically recyclable but lack widespread local recycling infrastructure.
The format also helps mitigate consumer waste. Liquid plant milks are often discarded before the end of their useful life once opened; by contrast, dry slices can be portioned precisely and hydrated as needed, lowering the risk of spoilage.
Market positioning and retail potential
From a commercial perspective, dry plant-based milk slices open up new merchandising and category expansion opportunities.
The compact, ambient-friendly packs take up less shelf space and reduce weight, potentially lowering retailer logistics costs and enabling placement in non-refrigerated sections near cereals, coffee or smoothies — creating cross-category presentation opportunities that could grow overall basket size.
With suggested retail prices reported to be competitive with conventional plant-based milks, the format may also appeal to price-sensitive shoppers while addressing sustainability expectations increasingly factored into purchasing decisions.
Innovation beyond flavour: format as differentiator
Industry analysts highlight that plant-based milk innovation has, until recently, been primarily driven by new base ingredients (eg, pea, rice, hemp) and flavour extensions aimed at boosting consumption occasions.
For example, flavoured alternative milks and other product extensions have helped grow overall market sales, which reached approximately $27-billion globally in 2025.
Dry oat milk slices represent a format-first approach — repositioning the product experience itself rather than focusing solely on ingredient or flavour.
This aligns with broader trends in packaged foods where convenience, sustainability and system efficiencies are as important to consumers and retailers as taste and nutrition attributes.
Industry implications and strategic considerations
For category leaders and innovators in plant-based beverages, oat milk slices offer a case study in how process and packaging innovation can create new competitive space. Key strategic considerations include:
- Supply-chain redesign: Lower shipping weights and reduced packaging may cut costs and emissions, but will require recalibration of production, distribution and merchandising workflows.
- Consumer education: Unfamiliar formats must be supported by clear usage instructions and marketing to drive trial and habitual use.
- Cross-category alliances: Positioning dry oat milk slices alongside complementary products (e.g., coffees, cereals, nutrition powders) could broaden placement and uplift overall sales.
