Covid Nineteen Pandemic [Abstract]
COVID-19 Pandemic	B.COVID-19 Pandemic The Company began seeing the impact of the COVID-19 pandemic on its business in early March 2020. The direct financial impact of the pandemic primarily included significantly reduced keg demand from the on-premise channel and higher labor and safety-related costs at the Company’s breweries. In addition to these direct financial impacts, COVID-19 related safety measures resulted in a reduction of brewery productivity. This has shifted more volume to third-party breweries, which increased production costs and negatively impacted gross margin rates. In the 13-week period ended March 28, 2020, the Company recorded COVID-19 pre-tax related reductions in net revenue and increases in other costs of $10.0 million. This amount consists of a $5.8 million reduction in net revenue for estimated keg returns from distributors and retailers and $4.2 million of other COVID-19 related direct costs, of which $3.6 million are recorded in cost of goods sold and $0.6 million are recorded in operating expenses. In 2021 and going forward, the Company has chosen not to report COVID-19 related direct costs separately as they are viewed to be a normal part of operations.
