Breweries produce beer through mashing, boiling, fermenting, conditioning, filtering, and packaging — operating at scales from small craft breweries to large production facilities. The technical challenges can include developing fermentation processes for consistency targets, optimizing yeast and process variables, evaluating ingredient interactions, improving filtration and process control, scaling up from pilot to production, and achieving packaging stability. This page explains what development work may look like in a brewery and how it relates to qualified research under Section 41. It is educational and is not individualized advice.
What R&D May Look Like in Breweries
Brewing involves fermentation process development, yeast and process variable optimization, filtration and process control development, and scale-up. Technical development may arise when a brewery develops a new fermentation process for a consistency target, evaluates yeast or process variables, improves filtration or process control, or scales up from pilot to production. Work directed at resolving genuine technical uncertainty in these areas — through a structured evaluative process — may warrant review under the four-part test.
Industry-Specific Examples of Technical Development
- Developing fermentation processes for consistency targets where the fermentation performance is uncertain.
- Evaluating yeast and process variables where the variable performance is uncertain.
- Improving filtration and process control where the control performance is uncertain.
- Scaling up from pilot to production where the scale-up behavior is uncertain.
- Improving packaging stability where the stability performance is uncertain.
None of these constitutes qualified research by itself. Each depends on whether the work satisfies all four elements of the four-part test.
Technical Uncertainty Examples
- Whether a modified fermentation process can achieve the specified consistency target across batches.
- Whether an alternative yeast strain can achieve the specified flavor and attenuation targets.
- Whether a new filtration approach can achieve the specified clarity and stability targets.

Process-of-Experimentation Examples
- Running fermentation trials with alternative processes, measuring consistency, and comparing results.
- Testing alternative yeast strains and process variables, measuring performance, and evaluating results.
- Testing alternative filtration approaches, measuring clarity and stability, and comparing results.
For more, see our page on process of experimentation.
Potential Business Components
Potential business components may include a new or improved product (a beer with improved consistency or stability), a new or improved manufacturing process (a fermentation or filtration process), or a new or improved technique (a yeast or process control method).
Employee Work That May Warrant Analysis
Employees whose work may warrant analysis include brewmasters developing processes, fermentation specialists optimizing variables, and quality personnel conducting consistency and stability testing tied to a development project. For more, see our page on R&D tax credit employee wages.
Contractor Work That May Warrant Analysis
Contractor work that may warrant analysis includes yeast and ingredient suppliers, filtration equipment vendors, and testing laboratories — where the brewery bears the economic risk and retains substantial rights. For more, see our page on R&D tax credit contractor costs.
Supplies and Materials That May Become Relevant
Supplies that may become relevant include malt, hops, yeast, and filtration material consumed in trials. For more, see our page on R&D tax credit supplies.
Activities That Generally Require Caution or May Not Qualify
- Routine batch production using established recipes and processes.
- Seasonal flavor changes based primarily on taste preference.
- Standard fermentation, filtration, and packaging following established procedures.
- Ordinary quality control and inspection.
- Copying an existing recipe with a minor ingredient change.
Documentation That May Help
Records that may help include project descriptions, fermentation and filtration trial records, consistency and stability test results, and records connecting personnel and materials to specific development projects. For more, see our page on R&D tax credit documentation.
Example Hypothetical Project
The following is a hypothetical example for illustration only. It does not represent any actual company and does not state that the work qualifies.
A brewery is scaling up a new beer style from pilot to production volume where the pilot fermentation process produces unacceptable consistency variation at scale. The technical uncertainty is whether an alternative yeast strain, a modified fermentation temperature profile, and a new filtration approach can together achieve the consistency, clarity, and stability targets at production scale. The team runs fermentation trials with three yeast strains and two temperature profiles, measures consistency, attenuation, and clarity, and evaluates stability. Based on the results, the team selects a yeast and temperature profile and refines the filtration approach. Records of the alternatives, test conditions, and results may help support analysis — but professional review is still needed.
Questions to Ask Internally
- What specific business component was being developed or improved?
- What technical uncertainty existed at the outset?
- What alternatives were evaluated, and how were they tested?
- Who performed or directly supported the work?
- What materials were consumed in the testing?
- How does this differ from routine brewing or seasonal recipe changes?
Relationship to the Four-Part Test
The four-part test applies the same way it does in any industry. The work must be directed at developing or improving a business component (permitted purpose), must fundamentally rely on principles of the physical sciences or engineering (technological in nature), must be intended to eliminate a technical uncertainty (elimination of uncertainty), and must be conducted through a structured evaluative process (process of experimentation). Meeting one element is not enough.
Key Takeaway
Breweries may perform activities that warrant analysis under IRC §41 — particularly work involving fermentation processes, process control, and scale-up. Seasonal recipe changes based primarily on taste and routine batch production do not automatically qualify. Professional review is appropriate.
