Our sister shop dwelltime 364 Broadway in Cambridge is doing cold brew by the bottle. Drop by and take one home. These growler sized bottles are placed front right in a wine fridge and bottled multiple times a week during the summer.
The Boston Globe recently did it's annual iced coffee article and gave the cold brew a review:
"Even if you take milk in your coffee, sample this coffee black at first. It has a natural sweetness and a toasty caramel finish, without a bitter taste. It is smooth, satisfying, and just right — the purest cold-brew drink we find." By Debra Samuels JULY 30, 2013 | GLOBE CORRESPONDENT
