Spring Fever, Spring Beer. Brewer Mark daSilva says spring's a great time to explore. To some, spring is a time of warmer weather, rebirth, and awakening of things gone dormant. To others, it’s a time to get their hands dirty and reconnect with the piece of earth that they call home. But to a beer drinker and brewer such as myself, it is a time of switching from big, bold and boozy beersto lighter styles.
