Project Barista: Viva Patrón

Siren Craft Brew

£2.5

Project Barista combines two of our greatest passions, beer and coffee, and plays with the relationship between them. Four unique beers, four kinds of coffee used in different ways, in collaboration with four incredible independent roasters. The Dark Ale incorporates tequila-soaked oak, agave syrup, intense espresso and Muscovado sugar for a coffee liqueur experience in a beer.

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as SIREN CRAFT BREW LIMITED, number 08182663. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Stated by the company: "Warehouse and eCommerce Operative Siren Brewery, Finchampstead" Source.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
No majority shareholding traced outside the UK. Companies House.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
