There is something genuinely clever about Aero. On paper, selling chocolate with less chocolate in it should not work. In practice, those bubbles have been making people happy since 1935, and the bar has outlasted dozens of trends, reformulations and chocolate fads without ever needing a rebrand or a celebrity to shift it.
If you are new to Aero or just want to know what is actually in the range right now, this is the full rundown.
A brief history of Aero
Aero was launched in 1935 by Rowntree’s, the York-based confectioner. The idea was straightforward enough: inject air into chocolate to create a lighter, bubblier texture. It worked. The bar was a hit from the start and was exported to North America and other markets within its first year.
Rowntree’s was acquired by Nestlé in 1988, and Aero has been part of the Nestlé family ever since. The core recipe has stayed pretty much the same across those nine decades. The bubbles are still there, the chocolate is still smooth, and the bar still melts in a way that feels different to a solid chocolate slab.
What makes Aero different?
The texture is the whole point. Those air bubbles are not just a gimmick. They change how the chocolate melts on your tongue, giving you a lighter, creamier mouthful than you’d get from a solid bar of the same weight. It is why Aero fans tend to be quite loyal. Once you are used to that texture, a regular chocolate bar can feel a bit heavy by comparison.
The bubbles are created by whisking the chocolate mixture and then allowing it to set under controlled conditions, trapping the air inside. Simple idea, distinctive result.

The Aero range: every flavour available in the UK
The current UK range covers a decent spread of flavours and formats.
Milk chocolate is the original and still the most popular. The 90g block is the one to buy if you want a proper amount of Aero rather than the snack-sized bar. It is the same bubbly milk chocolate that launched in 1935, and it holds up.
Peppermint is arguably the flavour most associated with Aero in the UK. The combination of cool mint and milk chocolate works particularly well with the bubbly texture, because the mint flavour carries through the melt in a way it would not in a denser bar. You can get peppermint Aero in a single bar format or as a block, which is worth knowing if you are buying for multiple people.
Orange is the newer addition to the block range and a good one. The orange flavour is genuine rather than synthetic-tasting, and it pairs well with milk chocolate without being overpowering.
Hazelnut is the sharing bar option, coming in at 90g. Hazelnut and chocolate is a reliable combination, and the Aero version adds the bubbly texture to something that usually comes in a denser format from other brands.
Mint bubbles are the standalone bag format. Rather than a bar, you get individual chocolate pieces filled with peppermint. They are good for sharing or for anyone who wants the Aero mint experience without committing to a full bar.
Melts are the newest format in the range. The 80g bag contains small chocolate pieces designed to melt more quickly than a bar, which makes them more of a snacking option than a sit-down chocolate experience.
Which Aero is best for buying in bulk?
If you are stocking up for an office, a party, or just want to make sure there is always Aero available at home, the block and bar formats are the most practical. The peppermint single bars are particularly popular for events because they are individually wrapped and easy to hand out. The melts and bubbles work well in a sweet bowl or gift bag scenario.
You can browse the full Aero range at One Pound Sweets and buy by the case. Buying in case quantities always works out better value per bar than picking up individual packets from a supermarket, and with free delivery available it is the obvious way to stock up properly.
