Description

Make your beer buying easy and affordable with our popular mystery boxes!

Each Mystery Box includes at least 10 unique beers (a mix of 330ml and 440ml sizes), with a built-in discount of AT LEAST 20% off each time. The ideal way of filling your fridge with brewery-fresh cans. This is our strongest always-on deal you'll find on our webshop, and it's a great way for new Siren fans to try something new.

Choose between our "Light Beer" box (all pale beers) and our "Light & Dark" box (a roughly even mix of pale beers and stout/porter styles).

*Saving is included in the price shown. Cannot be combined with other discount codes including investor discounts. Box may contain cans with gluten and lactose. This is a pre-set box, and so ordering multiple boxes will give you the same beers.

Please note picture is not representative of packaging - your cans will have the labels on as normal!

Nope! All cans include in our Mystery Boxes are well within their best before dates. Some might be fresher than others, but all are tasting absolutely fantastic.


You'll always save at least 20% off against the cost of the individual cans. If you're a lover of any and all beer, this is an absolute steal.

Yep! Don't worry, the beers you'll find inside these boxes are no different to our usual labelled beers you'll find online and in stores.

We wouldn't dream of it. If your box were to contain, for example, 7 x 440ml cans and 3 x 330ml cans, each beer would be completely unique and different from the others.

Almost. We update our Mystery Boxes every now and then depending on stock. But we always stick to a set list (this is how we guarantee your saving!) and our team don't just add anything they like in. That would be a stock-taking nightmare.
