When to hire a consultant brewmaster and what to expect
A consultant brewmaster is most useful at specific points in a brewery's life. This guide covers when to call one, what the work involves and how to tell a good one from an expensive visitor.
Signs you need one
Most breweries call a consultant either too early, before there is anything to fix, or too late, after the regulars have drifted away. The useful moments are more specific.
- Before you buy equipment. Brewhouse size, layout, utilities and tank count lock in your costs for years.
- At commissioning. The first weeks set the habits. Our commissioning checklist covers what to test.
- When batches vary. The same beer tastes different from one batch to the next and nobody can say why.
- When yield is low or losses are high. You buy more malt per litre than you should, or excise reconciliation keeps showing gaps.
- When the head brewer leaves. Recipes and know-how walk out with them unless they were written down.
- When you add an unfamiliar style. A German lager in particular demands water treatment, yeast handling and fermentation control that an ale-focused team may not have.
What a consultant brewmaster actually does
A good consultant finds the cause, fixes it with your team and leaves the fix documented. That means time on your brewhouse floor, reading your records, tasting your beer and watching a brew day from milling to knock-out. It also means writing: SOPs, specifications, tolerance bands and the order in which to tackle problems.
A consultant should not become a permanent dependency. If the brewery cannot run without them in the building, the job is not done.
What to expect from the engagement
- Health check. A site visit covering the brewhouse, cellar, cleaning, records, raw material storage and the beer itself. See what a brewery health check covers.
- Written action plan. Findings ranked by risk and payback. Hygiene and product safety come before recipe tweaks. Cheap fixes that remove real risk come next. Capital spending comes last, once the existing kit is running as well as it can.
- Hands-on work. Brew days alongside your team, adjusting the process and training on the job.
- Remote follow-up. Reviewing batch records and results over the following weeks until the changes hold.
How to prepare so the time is well spent
Consultants are most useful when they are not reconstructing basic facts. Before the first visit, gather:
- batch records for the last two or three months, however rough
- recipes as currently brewed, not as first designed
- malt and hop COAs, or at least supplier names and lot numbers
- any water test results
- cleaning chemicals, strengths and schedules
- the excise stock registers for the same period
If most of that list does not exist, that is a finding in itself. It is often the first fix.
Be honest about the problems you already suspect. A consultant who is told that the lager has tasted of butter since the summer, or that the excise registers have not reconciled for three months, can go straight to the cause. Hiding the awkward parts only means paying for the time it takes to find them again.
Questions to ask before you hire
- Where did they train? What systems have they run themselves? A brewer with years on 10 hl brewpub brewhouses knows different problems from one who has only worked in a large plant.
- Will they write things down? Ask to see the format of a past action plan or SOP with client details removed.
- How do they handle excise and licensing questions? A good brewer knows the process and knows when to send you to a licensing adviser.
- What happens when they leave? The answer should be a team that can run the brewery.
Consultant or full-time head brewer
A consultant does not replace a capable brewer on site every day. Most small brewpubs need both: a hands-on brewer who runs production and a consultant who sets up the system, trains the team and checks in. Our guide on choosing between a consultant and a full-time head brewer covers the trade-off.
If you recognised your brewery in two or more of the signs above, the cheapest time to act is now, while the problem is still a process and not yet a reputation.
Set expectations on both sides before work starts. Agree what the health check will cover, when the written plan arrives and who on your team owns each action. A consultant can show the way. Your brewers have to walk it every brew day after the visits stop.
Common questions
How long does a consultant brewmaster engagement last?
It depends on the problem. A health check and action plan can take a few days, while setting up a new brewery or fixing a quality problem usually runs over several weeks with remote follow-up.
Can a consultant work remotely?
Partly. Records, recipes and results can be reviewed remotely, but a site visit is needed to see the equipment, the cleaning and a real brew day.
Will a consultant change my recipes?
Only if the recipe is the problem. Most inconsistency comes from process, raw materials and fermentation control. The usual goal is to make your existing beers taste the way you intended.
