Paper Mill Coffee Roastery ★ 4.5
Paper Mill, founded 2020 by Margus Varvas, roasts in the old fire-station of the former Cellulose and Paper Factory, with up to 30 coffees a year.
Tip: Margus ran London's Mousetail chain before moving home; the flagship has a roaster on view, pastries from sister bakery Bakermill and recycled-husk cups.
