If you’ve ever stood in a craft brewery at 2 a.m., watching glowing wort bubble through a copper kettle, you know the heart of the operation isn’t just the beer—it’s the brewhouse system. When I started my company three years ago, supplying brewhouses to small batch breweries and regional producers, I quickly learned that the best equipment in the world is only as reliable as the care you put into maintaining it. I’ve seen breweries shut down for days because of a forgotten gasket or a missed valve cleaning, and I’ve helped clients avoid those missteps with a simple, consistent maintenance schedule. Today, I’m breaking down exactly what that schedule looks like, from daily checks you can do in ten minutes to annual overhauls that keep your system running for decades. Brewhouse System
Let’s start with why this schedule matters. A brewhouse isn’t a set-it-and-forget-it appliance. It’s a network of stainless steel tanks, pumps, valves, heat exchangers, and pipes that handle high temperatures, acidic liquids, and constant pressure. Skip a cleaning, ignore a small leak, or let a filter get clogged, and you’re not just dealing with dirty equipment—you’re risking off-flavors in your beer, batch failures, and expensive downtime. Over the past three years, I’ve worked with brewers ranging from 1-barrel home-brew setups to 30-barrel regional production facilities, and the core maintenance schedule stays the same regardless of size. It’s all about building habits that fit your workflow, so you don’t end up treating maintenance like an afterthought.
First up: daily maintenance. This is the stuff that happens right after brewhouse day, while the system is still warm but safe to touch. I always tell new clients to assign one person to lead these checks each day—rotating roles works, but having a point person means no detail slips through the cracks. The first step is a full visual walkthrough. I have a checklist taped to every brewhouse control panel that covers every valve, fitting, and gauge. Look for leaks: even a tiny drip from a steam valve can lead to corrosion over time, and a leaky inlet valve can throw off your mash pH by letting cold water in unexpectedly. Next, check pressure gauges for any readings that are out of the normal range. If your lautering tun’s pressure is 5 psi higher than it was last week, that’s a sign your filter plates are starting to clog and need attention.
Then comes the immediate post-brew cleaning, which is non-negotiable. After every brew day, you need to run a full cycle of caustic and acid solutions through the system. Most breweries use a CIP (Clean-in-Place) system, which is designed to circulate cleaning chemicals through all the pipes, tanks, and heat exchangers without taking the system apart. But don’t just hit the CIP button and walk away. I always tell clients to inspect the CIP return flow to make sure it’s not foaming excessively—too much foam means the solution isn’t reaching every part of the system, especially dead spots in the heat exchanger. For small breweries without a dedicated CIP system, you’ll need to disassemble and scrub surfaces, but even then, the daily cleaning should take no more than 45 minutes. One of my first clients, a 5-barrel brewery in Portland, used to skip a day of post-brew cleaning to “save time” and ended up with a batch of beer that tasted like metal—turns out a buildup of hop residue in the mash tun had corroded a tiny spot in the steel. We fixed the leak, adjusted their schedule, and they haven’t had an off-flavor issue since.
Weekly maintenance is the next layer, designed to catch issues that daily checks might miss. This is a good time to do a deeper dive into parts that don’t get touched every day. First, inspect all gaskets and seals. Gaskets on manways, sight glasses, and pump flanges wear out from constant exposure to heat and cleaning chemicals. Even a small tear in a manway gasket can lead to pressure loss during lautering, which can slow down the process and result in lower efficiency. I recommend keeping a stock of standard gaskets on hand—most brewers don’t want to wait three days for a replacement during a busy stretch. Next, check the pump impellers. These can get clogged with hop debris or grain dust over time, leading to reduced flow rates. If your pump is making more noise than usual or taking longer to move wort from the mash tun to the kettle, it’s time to inspect the impeller. Finally, test all safety features: pressure relief valves, temperature sensors, and emergency stop buttons. It’s easy to forget these exist until you need them, and a faulty pressure relief valve can lead to a dangerous steam buildup in the kettle.
I also add a weekly check of the control panel wiring and connections. Brewhouses run on electricity, and vibration from pumps and valves can loosen wires over time. A loose connection might not show up as an error on the control panel, but it can cause inconsistent temperature readings during the boil, which ruins hop bitterness and flavor. For breweries with automated systems, I always suggest logging data each week—temperatures, pressure, flow rates—so you can spot trends before they become problems. If your boil temperature is gradually dropping by 2 degrees each week, that’s a sign your heating element is getting scaled up and needs to be cleaned.
Moving to monthly maintenance, this is when you tackle parts that have longer lifespans but still need regular attention. First, descale your heat exchanger. Boiling wort and cleaning chemicals leave mineral deposits (scale) on the heat transfer surfaces, which reduce efficiency and force you to use more steam or electricity to reach the right temperatures. I recommend using a food-grade descaling solution—never harsh chemicals that can leave a residue that gets into your beer. To descale, you run the solution through the heat exchanger for 30 to 60 minutes, then flush thoroughly with water. For plate heat exchangers, you’ll need to take them apart and clean each plate individually. Another monthly task is checking your filter medium (whether it’s filter plates, diatomaceous earth, or a crossflow filter). Even if you’re not using it every brew day, the filter can get moldy or clogged from residual grain dust. Backflush it or replace the medium if it’s showing signs of wear.
Monthly is also a good time to service your pump. Most centrifugal pumps in brewhouses need a bit of lubrication on the shaft each month, and you should check for any play in the impeller—excess play can cause damage to the pump housing if left unattended. I always tell clients to keep a spare pump seal on hand; a blown seal can shut down the system for hours, especially during peak production season. Finally, do a full inspection of all pipes and fittings for corrosion. Stainless steel is durable, but it’s not indestructible—constant exposure to acidic wort can cause pitting over time. If you see any rust or discoloration on pipe fittings, replace them immediately, and address the source of the corrosion (usually from leftover residue not being fully cleaned after brew day).
Now, the big one: annual maintenance. This is a full, system-wide overhaul that happens at least once a year, usually during the brewery’s slow season (often winter, when beer sales are lower). I work with every new client to schedule a full system inspection and service within the first year of operation, and I recommend that they stick to that schedule. Annual maintenance includes disassembling all parts of the system: mash tun, lautering tun, kettle, heat exchanger, pumps, and valves. Clean every component thoroughly, removing all buildup that’s hard to reach during daily or weekly checks. Replace any worn parts that you spot during inspection—gaskets, seals, impellers, valve stems, heating elements. This is also the time to calibrate all sensors: temperature, pH, pressure. A misaligned temperature sensor can lead to over-boiling (which ruins hop aroma) or under-mashing (which results in low alcohol content). During the annual service, I also test all electrical components to make sure wiring is secure and no parts are at risk of failing. Many of my clients schedule this service during a planned shutdown, so they can use the time to clean their tasting room or update their taplist while the brewhouse is out of commission.
I’ve learned over the years that the key to a successful maintenance schedule is making it flexible. A 10-barrel brewery that brews three times a week has different needs than a 1-barrel nano-brewery that brews once a week. For smaller operations, you can adjust daily checks to be less formal—maybe just a quick look around before you start brewing, and a deep clean after. For larger production breweries, you might assign a maintenance technician to handle weekly and monthly checks, while the brew team does daily tasks. The most important thing is to document everything: when you changed a gasket, when you descaled the heat exchanger, when you calibrated the sensors. This log doesn’t just help you keep track of maintenance—it’s a valuable tool if you ever have an issue, because you can look back to see if a part was replaced or a cleaning was skipped around the time the problem started.
One common mistake I see breweries make is cutting corners on maintenance to save time or money. They use generic cleaning chemicals instead of food-grade ones, skip a weekly gasket check, or delay the annual overhaul. But the truth is, spending a few hours a week on maintenance saves you days of downtime and thousands of dollars in repairs. I had a client last year who tried to skip their annual service to run an extra brew batch, and their heat exchanger corroded so badly they had to order a replacement, which cost them $8,000 and shut them down for two weeks. That extra brew batch turned into a huge loss, and they learned the hard way that maintenance is an investment, not an expense.
At my company, we don’t just sell brewhouse systems—we support them for their entire lifespan. That means providing clients with customized maintenance checklists, on-site service for annual overhauls, and 24/7 access to replacement parts. We know that a well-maintained brewhouse isn’t just equipment—it’s the backbone of a brewery’s business. That’s why we work closely with each client to build a schedule that fits their specific workflow, not just a generic list off the internet.
