The 8-in-1 DIY Milk Frother You Can Actually Control

When making lattes at home, the milk frother is usually the first thing to fail: coarse foam, scorched bottoms, and plant milks that split. COLDFILL's 8-in-1 frother tries to fix all of it at once: cold froth, hot froth, heating and stirring modes in one unit, with four temperature levels from 36°C to 75°C — the low settings tuned for oat and other plant milks to prevent separation. Programs are DIY-customizable, so foam density and heat follow your taste. It handles dairy, oat, almond, soy and coconut milks for lattes, cappuccinos, iced coffee and macchiatos, with dry-boil protection and US/EU/UK plug versions. Launched in April 2026, it drew 1,107 backers who pledged about HK$750K (roughly $96K) — 7512% of its HK$10K goal.
