Moving from brewing into consulting work

Consultants sell judgement, not recipes

A brewery owner rarely hires a consultant to write a recipe. They hire one because something is costing them money and nobody on site can say why. Yield is low. A beer turns sour in kegs after three weeks. A new brewhouse is arriving and nobody has commissioned one before. The consultant's job is to find the cause fast, fix it and leave the team able to keep it fixed.

That last part is what separates a consultant from a contract brewer. If the brewery cannot run without you, you have built a dependency, not a solution. Good consulting work ends with written procedures, trained people and numbers the owner can track after you leave.

The work comes in a few standard shapes

Most brewing consulting falls into one of these:

• Start-up support: brewhouse sizing, layout, equipment specification and commissioning.
• Recipe and range development: new beers, scaled from pilot to production.
• Troubleshooting: infection, off-flavours, stuck fermentations, poor shelf life.
• Efficiency and cost: brewhouse yield, beer losses, energy and water per hectolitre.
• Quality systems: lab set-up, specifications, HACCP, sensory programmes.

Pick one or two you are strongest in. A consultant who claims all five usually delivers none of them well. If quality is your area, our guide on moving into quality management is a good companion to this one.

How much experience is enough

There is no fixed rule, but clients test you with one question: have you seen this problem before? A brewer with a few years on one 10 hl system has seen that system's problems. A brewer who has run several breweries, commissioned at least one and dealt with a serious infection has seen far more.

A fair test for yourself: list ten common brewery problems, from low brewhouse efficiency to high dissolved oxygen in cans. For each, can you explain the likely causes, the measurements that would confirm them and the fix? If you hesitate on more than two or three, keep brewing for now.

Measure before you advise

The habit that makes consultants credible is arriving with a measurement plan rather than an opinion. Brewhouse efficiency is a good example. Most well-run craft brewhouses land somewhere around 70 to 85% depending on the kit, the mill and the lauter. If a client reports 65%, a consultant does not guess. They check the crush, the mash pH (usually aimed at 5.2 to 5.6), the sparge temperature and volumes, the grain bill weights and whether the gravity readings are temperature corrected.

Half the time the problem turns out to be the measurement itself: an uncalibrated hydrometer or a mash tun volume nobody has checked since installation. Finding that is real value, even if it feels small.

Write everything down

A consultant's output is mostly documents: a site report, a list of findings ranked by impact, an action plan with owners and dates, procedures and training notes. Clients remember the visit. They keep the report. If your writing is weak, your advice will be lost within a month of leaving.

Practise now. After any problem you solve at your current job, write a one page note: what happened, how you diagnosed it, what you changed and the numbers before and after. Ten of those notes are the start of a portfolio.

Running it as a business

Consulting income is lumpy. A large start-up project may keep you busy for months, followed by weeks of nothing. Many brewers start part time, alongside a brewing job, if their employer allows it. Check your contract for any clause on outside work before you take a client.

Agree scope in writing before you start: what you will do, what you will not do, how many site days and what the client must provide. In India that often includes how travel between cities will be handled. Never promise an outcome such as a fixed percentage gain in yield. You cannot control how the client runs the brewery after you leave.

Your network is your pipeline

Most consulting work arrives through people who already know your brewing. It comes from former colleagues who open their own breweries, equipment suppliers who need someone to commission an install and owners who heard you helped a friend. Look after those relationships long before you go independent.

Your first step: write your ten problem list from section three tonight. Mark the ones you can solve cold. That list tells you what kind of consultant you are today and what to learn next.

Common questions

How many years of brewing experience do I need before consulting?

There is no fixed number. The real test is whether you have seen and fixed the common problems clients bring, from infection to low yield, across more than one brewery.

What do brewing consultants usually work on?

Start-up support and commissioning, recipe development, troubleshooting, efficiency and cost reviews and quality systems are the common types of work.

Can I consult while holding a brewing job?

Some brewers do, part time. Check your employment contract for any restriction on outside work first.

Should a consultant guarantee results?

No. Agree scope and deliverables in writing. Outcomes depend on how the brewery runs after you leave, which you do not control.
