Three breweries turned away from the Libramont fair over local barley. Behind the row, a Walloon supply chain coming back to life — and one link still missing: malting.
In late July, on the fairgrounds at Libramont, three Ardennes breweries found the door shut. Lupulus from Gouvy, Minne from Baillonville and des Tchets from Libramont itself were all turned away from the "Ardenne Joyeuse" pavilion for failing to meet a new charter requiring locally grown brewing barley. "We've been at the fair since 2009," Philippe Minne told the Belgian daily L'Avenir, adding that nobody had even warned him the rules had tightened. The story travelled well beyond the province of Luxembourg. And it raises the question we wrestle with every day in Dinant: what does it actually take to brew Belgian, from field to glass?
A charter that stung, a debate worth having
The method first. The manner of it deserves criticism: dropping loyal exhibitors without warning is poor form, and the brewers were right to say so. A transition is negotiated, not decreed between two editions of an agricultural fair. A brewer who has built recipes on one specific malt for fifteen years cannot switch suppliers the way you swap an aroma hop.
Then the substance. Behind the clumsiness, the Libramont charter points at something real: an "Ardennes" beer brewed with barley from far away, malted further away still, tells an incomplete story. Wallonia's biggest agricultural fair chose to push the local supply chain forward, even at the cost of ruffling feathers. The debate it opened needed opening — even if the door slammed rather hard.
A supply chain coming back from almost nothing
The figures tell a story of revival. In 2017 Wallonia had a mere 236 hectares of brewing barley left, according to the region's own agricultural statistics (État de l'agriculture wallonne). By 2023 the thousand-hectare mark had been passed. For 2026, L'Avenir reports around 1,700 hectares, roughly 11,000 tonnes of barley — enough, on paper, to brew over 400,000 hectolitres of beer. The Collège des Producteurs, which represents Walloon farmers, is aiming for 3,000 hectares. In under a decade, a crop written off as abandoned has become a real option again across the plains of Hesbaye, the Condroz and beyond.
Wallonia carries the Belgian crop. Roughly nine tenths of Belgium's brewing barley grows on Walloon soil, the same statistics show. For a region home to nearly 40% of the country's 417 or so breweries, that is a serious card to play: the grain, the water, the brewers and the drinkers are already here.
The missing link is malting
A quiet bottleneck. Between field and mash tun sits the step most people forget: malting. Belgium produces around 966,000 tonnes of malt a year, yet malt made from Walloon barley accounts for less than 1% of it, according to the regional figures. The country has only a handful of maltings, and just a minority of them work with local grain. In other words: you can sow all the hectares you like, but as long as the grain travels far to be malted — or finds no maltster at all — the local loop stays open.
This is exactly where we come in. In Dinant, our 5-tonne germination-and-kilning drum will handle about one batch a week, starting with our first malting campaign in mid-October. Belgian organic barley — including grain from the founder's own Demeter-certified farm and from a Belgian organic farming cooperative — malted without fossil fuels: the kilning heat comes from biomass, carried by hot water, and the electricity is renewable. One craft malthouse will not close the Walloon loop on its own, but every tonne malted here is a tonne that no longer crosses Europe by lorry.
Local, yes — but without dogma
When local malt is not the right choice. Let's be honest, because brewers already know this: a craft malthouse does not replace everything. A stout will still need roasted malts that few small houses produce. A brewery shipping serious volumes against a tight specification has every reason to value the consistency of a large industrial malting. And a small operation malting one batch a week will never supply everyone. Local malt is meant to become the heart of a brew — the base malt, pils or pale ale, that makes up 80 to 90% of the grist — not to do everything, all at once.
Organic has its own arithmetic. Brewing barley yields about 6.5 tonnes per hectare grown conventionally, against 4.5 tonnes organically, per the Walloon figures. Lower yields, more work, stricter sorting: organic grain is earned. That is the price of living soil and fields free of synthetic inputs, and it is a choice we stand behind — but it would be dishonest to pretend it doesn't show up in a brewer's sums.
What Libramont leaves us with
A supply chain is built by supply as much as by rules. A charter can demand local barley; local malt still has to exist — at brewing quality, in sufficient quantity, in the styles brewers actually need. This summer's row is above all a reminder that the demand is there, the hectares are following, and it is now the malting link's turn to grow. That is precisely the work we have taken on in Dinant.
If any of this speaks to you — whether you brew in your cellar or in a microbrewery, or you're simply curious what happens to a barley grain between the combine and your glass — the malthouse door is open. Come and see the drum before the first barley goes in this mid-October, or write to the team through mad.be: we talk malt gladly, and at length.
