Drinking occasions outside the home plummeted in recent months due to COVID-19 containment measures. Yet Boston Beer entered the crisis period with unusually strong momentum. Sales jumped 32% through late February, the company said on April 22, in part due to consistently strong demand for its Truly Hard Seltzer brand.
