The Solo is a flat-bottom, wave-filter dripper from Mazelab Coffee (Prague), designed by barista Jackie Tran after his 2024 World Brewers Cup run. Its defining trait is a large single central drain under 40° walls, which gives a fast, high-clarity flow — Tran's idea that "a faster dripper gives you room to slow down when needed." Reduced channeling from the geometry and a paper you can lift slightly off the base for even quicker drainage make it forgiving and clean. It is moulded from food-safe, BPA-free plastic (about 98 mm across, 1-2 cup) and sits directly on most glass servers; a Terra variant uses repurposed coffee waste.
It uses flat-bottom wave papers — the premium Solo Wave Hiflux (co-developed with Hiflux, lyocell-fibre) or the everyday Solo Wave Daily — and pairs with the Solo Glass Server or the ceramic SIP sensory server-cup. George Jinyang Peng won the 2025 World Brewers Cup on the Solo; Jackie Tran placed fourth at the 2026 World Brewers Cup in Brussels, leading Round One. For the 2026 final Tran ran a switch-equipped variant ("Solo Spin") that adds a valve for immersion phases — the recipe here uses it.
Starting recipe (everyday percolation): 15 g to 250 g (about 1:16.7) at 93 °C, a 50 g bloom for 30 seconds, then two pours, finishing around 2:30-3:00. Choose the Solo when you want a fast, clean flat-bottom cup with room to shape the pour.
