Your worktop is full of living things. Brinepost keeps track of all of them.
Start a batch — sourdough starter, kombucha brew, kimchi jar, or yoghurt — and Brinepost runs the day clock, sends the right reminders, and keeps the log you'll actually look back at.
TRACK EVERY BATCH
• Day counters and progress for each active ferment
• Per-ferment details: hydration, salt, volume, vessel, source
• Opt-in observation sliders: rise, bubbles, aroma, tang, texture
• Temperature in °C or °F, notes, and a photo log day by day
REMINDERS THAT MATCH THE FERMENT
• Daily feeding reminders for your starter at your preferred hour
• Check-in schedules for kombucha, kimchi, and yoghurt
• Kombucha second ferment: move to 2F and the day clock and carbonation checks restart for the bottling stage
THE BUILT-IN GUIDE
• Stages, common questions, and "what you might see" for all four ferments — written for real batches, fully offline
• Guided troubleshooting that answers from the guide
• For consumption questions the guide always points to official sources — Brinepost never makes food-safety calls
PRIVATE BY DESIGN
