174 Layoffs Set for Next Month as Baltimore Guinness Brewery Closes

A Baltimore brewery closure will eliminate 174 jobs next month, according to industry trade outlet Brewbound, which first reported the workforce reduction tied to the Guinness Open Gate Brewery shutdown.

The figure positions the impending layoff as one of the larger single-site brewery reductions publicly disclosed in the Mid-Atlantic region this cycle. The facility, operated under the Guinness Open Gate Brewery brand in Baltimore's Halethorpe neighborhood, combines production operations with a consumer-facing taproom and event space.

For affected workers, a single-site reduction of this size carries concentrated risk. Displaced employees face simultaneous entry into local hospitality and manufacturing labor pools rather than gradual attrition across a portfolio, compressing job-search timelines within a single regional market.

What is driving the closure?

The source material provided does not state a reason. Brewbound's headline identifies only the layoff count and the timing. No executive comment from the operating company appears in the available filing, and no labor-union representation details are provided.

Workers affected by a closure of this scale in Maryland would typically be covered by the federal Worker Adjustment and Retraining Notification (WARN) Act. That statute requires employers with 100 or more full-time employees to provide 60 days' written notice of mass layoffs or plant closings.

A 174-position reduction exceeds that threshold by 74 positions. The operating entity would be expected to file a WARN notice with the Maryland Department of Labor. Maryland maintains a public WARN registry that typically surfaces filings within days of receipt, and the document usually discloses position counts, separation dates and whether bumping rights apply.

What does the timeline look like?

The Brewbound headline references "next month," placing the effective date within roughly 30 days of the article's publication. Without a specific calendar date or the underlying WARN filing in the available source, an exact separation date cannot be confirmed.

The 60-day WARN window, if the notice has already been issued, would have started counting backward from the closure announcement. Employees in production, packaging, hospitality and brewery operations roles would typically be represented in a closure of this size, though the source does not break down the 174 positions by function, pay band, or union status.

Severance terms, continuation of health coverage under COBRA, and any transition assistance would also be detailed in the WARN filing once published.

What remains unconfirmed

The Brewbound headline constitutes the sole datapoint in the source material. No executive statement, WARN notice text, or severance framework appears in the provided data.

Workers, suppliers and the surrounding Halethorpe hospitality ecosystem will receive further detail once the official notice is posted publicly. The 174-job reduction, once formally posted, will enter Maryland's quarterly mass-layoff ledger alongside other brewery and food-manufacturing contractions of the year.
