Beer from oysters

By: Joshua Kyle

Walled City Brewery is an independent brewery in Londonderry which prides itself in providing patrons with a ’taste of the North West‘ by crafting local, authentic, premium quality, flavoursome beer and food. Inspired by Guinness’ suggested serving of oysters with stout, the challenge was laid down to the brewers to develop a beer using local Lough Foyle oysters and so Foyster Stout was born.

As with all great challenges, research was needed before jumping into the beer-making by looking to other breweries such as Maine’s ’Out-To-Sea‘ imperial stout in the USA or Dublin’s own Porterhouse’s beer, ’Oyster Stout‘.

A sustainably sourced supply of oysters was required for the beer and that’s why we selected the Lough Foyle Irish Flat oyster—the Loughs Agency, operated jointly by Ireland and Northern Ireland, has worked extensively on this species, as have members of the GAIN team. The oysters were sourced from licensed farmers—it is vital for us and for our customers that we use the best ingredients from sustainable suppliers.

The use of the oyster had a dual purpose in the brewing process. Firstly, the flesh was used in the mashing process which extracts natural sugars—the flesh gives a fantastic marine essence to these sugars. Secondly, the shells contain a high amount of calcium carbonate which is used as clarifying agent of the beer. This ensures every part of the oyster is used and nothing is wasted.

The Walled City Brewery launched the beer on 12th October, 2019 which was widely well received. It will be going on sale as a seasonal beer and Foyster Stout will be available in selected bars and restaurants in the city. We’re grateful to the Loughs Agency for their support in our development of this new beer which will help raise awareness for the Flat Oyster.

GoodFish

As consumers what do we look for in our food? Something tasty, that we like, want and are able to find in our towns and cities. We look for healthy options, at least as far as we are able or willing to go. Fish – or shellfish – either farmed or wild mostly fits such criteria, especially when compared to other available animal protein sources.

We also want safe seafood, which is nowadays commonly available at most supermarkets, fish markets and even online. For most consumers on top of these considerations is the most important factor: cost. A fish that would check all of these boxes at a reasonable price, could be considered to be a GoodFish.

Although these aspects shape our choices, other considerations have entered our plates recently: now we also want our fish to be fed, grown, processed and transported sustainably – in its three-pronged meaning: ecological, social and economic.

Inside each of these three aspects of sustainability resides a multitude of components which include genuine concerns such as animal welfare, gender equality, environmental protection and waste reduction objectives which fuel the implementation of circular economy principles.

Coupled with these recent requests (and partially originated by them) also stems a demand for higher trust in the food we purchase, hence the growth in innovative technologies who enable companies to increase the traceability and transparency of their supply chains, and empower us, consumers, (ideally) to also bask in the benefits of such tools. Shortly: we want to know more about what we eat so we can shape our consumption knowingly.

On the other side of this “coin” we have: 1. Regulators seeking to create conditions that promote sustainable practices; and 2. The seafood industry, who keeps providing an ever-increasing amount of fish and shellfish to our plates, while providing livelihoods to millions of people.

In order to figure out how to breed higher quantities of fish with less environmental impacts, while not trampling over animal welfare or human rights, could be (in fact is) a tough, reachable and critical task. That is why innovations stemming from science and businesses that can help us reach these goals will play a role. In working together and combining them we can reach that sweet spot: a GoodFish.
