Aero is one of the only major chocolate bars where the texture, not the flavour, is the entire selling point — people search for it specifically because of the bubbles, and the bubbles are exactly what the name is describing.
Launched in York in 1935, named for the process
Aero was created by Rowntree's in York, England, and launched in 1935. The name comes directly from aeration — the manufacturing process of whipping air bubbles into the melted chocolate before it sets, which gives the bar its honeycomb-like cross-section and a lighter, faster melt than a solid bar of the same size. The brand is now owned by Nestlé, which acquired Rowntree's in 1988.
From a single bar to a small family of spin-offs
The original mint and milk chocolate Aero bars spent decades as the whole range, but the aeration idea has since been applied well beyond the classic bar — including Aero Bubbly, which reworks the same bubbly texture into a different bar format, and crossover products that pair the Aero texture with other Nestlé chocolate bases entirely.

FAQ
Why is Aero chocolate bubbly?
It's whipped with air during manufacturing — a process called aeration — which creates small bubbles throughout the chocolate, giving it a lighter texture and faster melt than a solid bar.
Who makes Aero now?
Aero was created by Rowntree's in 1935 and is now owned by Nestlé, which acquired Rowntree's in 1988.
What's the difference between Aero Bubbly and Aero Milkybar?
Aero Bubbly is the standard aerated milk or mint chocolate bar with no Milkybar branding. Aero Milkybar applies the same aerated texture to Milkybar's white chocolate base instead, and is sold under both brand names on the same pack.
Is Aero in stock at Supreme Sweets right now?
Yes — both the Aero Bubbly milk and peppermint cases and the full Aero Milkybar line are currently in stock and available to order.
