Weekly Craft Stress Index (CSI) Explanation

The Weekly Craft Stress Index (CSI) is a composite gauge of how hard it is to operate a craft brewery in the U.S., scored from 0–100:

  • 0–30: Expansion / Low Stress

  • 31–50: Neutral / Stable

  • 51–70: Contraction / Elevated Stress

  • 71–100: Severe Stress / Survival Mode

It blends five key pressure points, each scored 0–100 and weighted to produce one headline number:

  1. Market Health (25%) – Closures vs. openings, bankruptcies, and taproom hour cuts show whether the core business environment is expanding or shrinking.

  2. Distribution Pressure (20%) – Purchaser sentiment, distributor consolidation, and depletions trends capture how hard it is to win and keep spots on trucks, taps, and shelves.

  3. Cost Stress (20%) – Movements in aluminum, grain, hops, labor, and freight show how much margin squeeze breweries are feeling.

  4. Revenue Signal (20%) – On-premises traffic, average check size, and the taproom–wholesale gap reveals how demand and mix are shifting.

  5. Capital & Liquidity (15%) – Lending appetite, PE/M&A activity, and delayed expansion projects reflect how much financial oxygen is available to the sector.

Together, these components offer a directional, week-to-week read on whether the craft beer operating climate is getting easier or harder.


Historical CSI Data (2020–2025) & Seasonality
The CSI tracker launched in January 2026, which means there is no real-time historical record to compare against. To understand whether what we are observing week-to-week reflects a genuine trend movement or simply the time of year, a synthetic historical dataset was constructed covering January 2020 through December 2025 spanning 312 weeks of data.

How the historical data was generated
The historical dataset was built using the same five-component methodology and weighting structure as the live CSI tracker. Rather than being fabricated arbitrarily, each component was anchored to documented industry conditions for the corresponding period. Key historical reference points embedded in the model include:

  • 2020 (COVID shock): Market Health and Revenue Signal spike sharply beginning mid-March 2020 as taproom closures were mandated nationwide. The composite CSI peaks in the low-to-mid 80s during April before gradually easing as outdoor service and to-go sales provided partial relief through the summer.

  • 2021 (reopening boom): The most stress-free period in the dataset. Craft volume grew approximately 8% as on-premise reopened fully, capital was accessible, and distributor sentiment recovered. CSI trends down into the 42–52 range for much of the year.

  • 2022 (inflation and supply chain): Cost Stress becomes the dominant driver as aluminum tariffs, grain prices, and freight costs all spiked. The CSI climbs back into the upper 50s to mid-60s.

  • 2023 (saturation signal emerges): Market Health and Distribution Pressure begin worsening in earnest as closures accelerate and wholesaler sentiment softens. CSI trends into the 62–70 range.

  • 2024 (contraction confirmed): For the first time since 2005, brewery closures outpaced openings. The CSI reflects this shift, spending most of the year in the 68–76 range.

  • 2025 (severe stress baseline): The Beer Purchasers' Index remains deep in contraction, total brewery count declines, and all five components are under pressure. This is the baseline the live 2026 tracker picks up from.

Seasonality and normalization
One of the primary reasons for constructing the historical dataset below is to separate true trend movement from seasonal noise. The Revenue Signal component is the most seasonally sensitive. For example, on-premise traffic reliably softens in January due to the Dry January effect and post-holiday spending pullback. It recovers modestly around St. Patrick's Day, peaks through the summer taproom season (June–August), and sees mixed signals in Q4 as holiday demand and year-end capital tightening pull in opposite directions. Each week in the historical dataset includes a seasonal adjustment value which is the estimated number of points that time of year alone contributes to (or relieves from) the composite score. Subtracting this value from the raw weekly CSI produces a seasonally-adjusted reading that offers a cleaner view of the underlying trend. However, there is one important caveat. This historical data is synthetic. It is grounded in real industry events and directionally consistent with published data from the Brewers Association, Beer Purchasers Index, NielsenIQ, and Brewbound reporting but it was not produced by scoring each historical week in real time the way the live tracker is. It should be used as a directional reference for seasonal context and trend comparison, not as a precise historical record. You can see the historical data and seasonality adjustment charts below. I used the seasonality adjustment to adjust the live tracker and compare raw vs adjusted seasonal trends in real time.
