How it brews

The Copenhagen roastery's own flat-bottom paper, sold Small (≈Kalita 155 / Origami S) and Large (size 175, for the April plastic brewer). It's cut to sit deep with a wide base and is marketed as flowing faster than conventional flat papers — that speed claim is April's, kept as a class rather than a number here. One honest ambiguity: older retailer copy described April filters as using Sibarist's abaca FAST technology, while the current listing says virgin wood pulp (cellulose); we record cellulose per the direct listing but don't treat abaca as confirmed. It drops into a Kalita Wave 155/185 seat, so it interchanges with those papers.

How it brews

MHW-3Bomber's flat-bottom paper in the 155 class, a cellulose sheet for flat-bed brewers. It sits in the flat-basket family and interchanges with other 155-class flat papers there rather than with cones. MHW-3Bomber publishes no fast/medium/slow class, so we leave flow unrated. The flat bed spreads the coffee wide the way flat-bottom papers do; a pre-brew rinse is the usual habit.
