“BevOps applies DevOps principles to brewing to improve repeatability, observability, and continuous improvement while preserving the creativity and experimentation that make homebrewing enjoyable.”
Brew → Iterate → Improve → Enjoy
The BevOps philosophy is relatively simple. Beer is brewed under a wide range of conditions, so those conditions should be documented to allow for explicit repeatability of any given batch of beer. Large breweries even struggle with this to some degree. Maybe a batch of hops in a given year are particularly more bitter than previously. Maybe switching vendors for malt changed the flavor profile subtly but enough to notice. BevOps captures those changes to a specific “version” of your beer to the point where you can replicate it reliably.
The purpose of BevOps is not to eliminate creativity from brewing. The purpose of BevOps is to document this creativity so it can be repeated, improved, and shared.
BevOps may not be for everyone but the philosophy is rooted in structure, predictability, and reliability and can help any brewer make the best beer they wish to make. Readers should take the principles documented here as guidelines and not hard, fast rules. The goal of BevOps is to establish principles at a high level but leave room for flexibility in how they are implemented.
Beer has a lifecycle, and so it stands to reason that beer development has a lifecycle as well. BevOps seeks to incorporate the repeatability and “deployment” of beer in the same manner that DevOps does so with software.
But what are these cycles? Beer is as complex as software so let’s dig into what this lifecycle looks like.
Ideation → Recipe Architecture → Development Brew → Testing & Validation → Deployment → Monitoring & Observability → Iteration
This is where beer takes root. It’s an idea. It’s drinking a beer and thinking, “This would taste better with different hops”, or even “I think I can make a better wit by adding a bit more coriander”. Ideation is the playground of amazing beer and absolutely where your favorite beer started.
Once you have an idea the next step is to formulate the recipe. What is actually going to comprise this beer idea? Documenting your recipe is a critical component to creating a specific batch of beer to a specific set of expectations.
Development Brew is the execution phase of the Beer Development Life Cycle. During this stage the recipe architecture is transformed into a physical batch of beer through mashing, boiling, fermentation, and conditioning.
The goal of a Development Brew is not necessarily to produce a perfect beer, but to generate a real-world implementation of the recipe design that can be evaluated through Testing & Validation.
Testing & Validation is the process of determining whether a beer successfully met its intended design goals. While brewing and fermentation produce the beer, testing & validation confirms whether the resulting product aligns with the recipe specification, quality objectives, and brewer expectations.
Deployment is the process of preparing and releasing a validated beer for consumption. Once a batch has successfully completed Testing & Validation, it enters Deployment where it is packaged, conditioned, labeled, and made available for serving. This is transferring your fermented, finished beer to bottles, kegs, growlers, or whatever you intend to distribute to your audience.
Monitoring & Observability is the practice of collecting, reviewing, and analyzing brewing data throughout the lifecycle of a beer in order to evaluate performance, identify trends, and inform future improvements. That’s a fancy way of saying that you track feedback from people who drink your beer (yes, even yourself!), demand for your beer, what its shelf-life is, does it get better or worse over time, etc.
Monitoring focuses on tracking known metrics and conditions. Observability expands upon monitoring by enabling brewers to understand the relationships between those metrics and the resulting quality of the finished beer.
The goal of Monitoring & Observability is not simply to collect data, but to generate actionable insights that improve future batches.
Monitoring answers:
What happened?
Examples:
Original Gravity was 1.052
Final Gravity was 1.011
Fermentation lasted 8 days
Average fermentation temperature was 67°F
Carbonation reached target levels
Observability answers:
Why did it happen?
Examples:
Why did attenuation increase compared to the previous batch?
Why did the beer finish drier than expected?
Why did hop aroma fade more quickly than usual?
Why was this batch clearer than previous releases?
Once you monitor and observe a batch, collect metrics, and determine the final result, there is the choice to iterate on the batch. Ideally iteration is improvement, or at minimum change. Perhaps feedback from others was negative and you want to make improvements. Maybe you decide to take a beer in a different direction. Any change from a specific batch of beer should be viewed as an iteration.
Iteration is the heart of BDLC. Iteration is taking all of the other BDLC concepts and learning from them. Beer evolves but iteration isn’t even always about evolving. It’s about learning and adapting. Iteration is about change.
Every batch, successful or otherwise, produces knowledge. BevOps treats that knowledge as an asset to be documented, preserved, and applied to future releases.
The goal of iteration is not perfection. The goal of iteration is continuous improvement.
Brew → Iterate → Improve → Enjoy
Good brewers keep detailed brew logs for their batches to review like baseball box scores. This data helps understand and improve the process over time. In BevOps, recipe versions should be defined using semantic versioning guidelines to help the brewer identify the batch and quickly determine where it is in the Beer Development Life Cycle (BDLC). BevOps defines this as “Semantic Fermentioning” or “SemFer”.
As noted previously, beer changes. That’s a natural given in brewing. It’s rare that a beer stays 100% the same forever. That’s just a natural evolution of the craft. BevOps factors that in by “versioning” batches and carefully documenting what changed to allow for repeatability. Imagine brewing a hefeweizen that you loved and then a year later brewing a slightly different batch. Maybe you didn’t particularly care for the new batch and really wanted to brew the original one you loved. Traditionally you’d have to rely on detailed brew logs and memory but with documented Semantic Fermentioning you can easily retrieve all of the ingredients, brew steps, and nuances that made a specific batch unique.
Guidelines for SemFer are as follows:
v0.x.x = Experimental releases
v1.0.0 = First approved production recipe
v1.1.0 = Minor recipe refinement that intentionally affects flavor, aroma, body, or mouthfeel while preserving the beer’s overall identity.
v1.0.1 = Small operational “tweak” to recipe.
v2.0.0 = Major recipe ingredient/profile change
Status Designations for batches should be as follows:
Experimental
Alpha
Beta
Stable
LTS
Deprecated
Archived
Example:
beer: Agave Drift
version: 0.3.0
status: Experimental
One of the core BevOps principles is to keep release notes for versions of beer. Similar to software, these release notes help identify what changed to make the batch the version that is it. Release notes should be clear and concise as to what changed if this is an iteration, or what the batch is composed of if it is a new release.
Release notes should include the following at minimum:
Summary
Motivation
Expected Outcome
Optionally:
Observed Results
Rollback Plan
Example:
Trailhead Wit v1.1.0
Summary: Increase coriander from 0.5 oz to 0.75 oz
Motivation: Enhance citrus aroma
Expected Outcome: More expressive nose
Observed Results: Pending
Purpose: Did the mash perform as expected before the boil?
Example:
Target Pre-Boil Gravity: 1.040
Purpose: Did the mash and boil process produce the intended wort?
Example:
Purpose: Did fermentation complete successfully?
Example:
1.010–1.012
Purpose: How effectively sugars were extracted from the grain.
Example:
Purpose: Fermentation effectiveness
Example:
75–80%
Purpose: Time to production readiness.
Example:
7-10 Days
Purpose: Process consistency.
Example:
Purpose: Did packaging perform correctly?
Example:
2.5 vols CO₂
Purpose: How much finished beer actually made it to packaging?
Example:
5 Gals Brewed
4.75 Gals packaged
Purpose: Beer lost to trub, spills, transfer, samples
Example:
Purpose: Percentage of batches shared with friends, family, or the community.
Because BevOps exists to make better beer, but beer exists to be enjoyed.
Operational frameworks like BevOps depend heavily on assessing the reliability of it. Applying a framework like BevOps is pointless without a way to determine if it’s working as expected.
In the same way that SLI and SLO metrics help track specifics of a batch like gravity, clarity, attenuation, BORA establishes metrics to help track the operational aspects of a batch.
Purpose: How often do you brew?
Example:
3 batches/month
Purpose: How long from idea to product?
Example:
Idea: May 1
First Taste: June 1
Lead Time = 31 Days
Purpose: Percentage of recipe or process changes that produce an undesirable outcome.
Examples:
Beer misses target profile
Unexpected off-flavors
Fermentation issues
Carbonation problems
Change did not achieve intended goal
Purpose: How long it takes to recover from a brewing incident.
Examples:
Infection
Stalled fermentation
Broken equipment
Failed recipe experiment
Purpose: How frequently a recipe changes. Helps to see which recipes are stable and which are still evolving.
Example:
Trailhead Wit:
4 changes in 12 months
Purpose: How often a recipe is brewed again.
Example:
El Pescador:
Purpose: How consistently you hit your targets,
Example:
Target Metrics: 10 Met Metrics: 9 Consistency Score: 90%
Purpose: Percentage of batches that have complete documentation.
Example:
Batches Brewed: 20 Fully Documented: 18 Coverage: 90%
Purpose: Would I brew this again?
Example:
Scale: 1-5 1 = Never again 3 = Worth revisiting 5 = Immediate rebrew
Things can happen when brewing beer that you don’t intend that can have a direct impact on the batch. These incidents should always be reported and documented to help prevent them from happening again in the future.
Example:
Incident #: BEV-2026-001
Summary: Tilt telemetry pipeline failed.
Impact: Lost 12 hours of fermentation data.
Root Cause: Brewer accidentally unplugged Tilt Pico while cleaning.
Resolution: Reconnected Pico.
Preventive Action: Do not unplug production monitoring systems while drinking production monitoring outputs. 🍺
