Batch 18: baechu kimchi sweetened only with pear

2026-09-20 · batch #18 · 3 heads · target: 4-6 week cold ferment

The change from batch 17's autopsy

Batch 17 went yeasty and fizzy because I added sugar AND fermented warm. This batch: zero added sugar, one ripe Korean pear blended into the paste, and the crost went straight into the kimchi fridge at 4°C for 48 hours before coming up to 18°C for a short bright ferment.

Day-by-day

Day 0: paste sweet-floral from the pear, almost candyish raw. Day 2: paste mellowed, edges rounding. Day 4 (today): the target — clean sour note on the back of the tongue, pear gone without trace, fish sauce behaving properly behind rather than on top. Carbonation: zero. This is the best day-4 of any batch so far.

Verdict so far: the pear is doing the slow, even feeding job sugar was doing badly, and without the sugar spike the yeast never got its opening. Will update Day 14 and at 6 weeks.
