Prestina rethinks the classic French press by removing the plunger and letting the cup itself drive the press: add coffee and hot water, stir, wait, then press, while a built-in duck valve holds the water during steeping for fuller flavour, and a permanent stainless-steel filter preserves more natural oils without paper filters. The brewer, cup and stirrer nest into one compact unit, making it equally suited to an office desk or a weekend bag.
