Fermentation Notes
Used the Igloo cooler for the first time for temp control (using ice packs), first night temp dropped to 62F. Fermentation was slow. Took it out of cooler, left at ambient. After 4 days SG was 1.022. Dropped in a starter made with US-04 slurry. After another 4 days SG was 1.021. Racked to secondary with vanilla bean soaked in vodka for a few days.

Packaging Notes
Time on vanilla bean in secondary was 1 week. Bottled.

Tasting Notes
Good cocoa/chocolate character, a bit bitter though. Good vanilla presence. Not quite as sweet/full bodied as Aphrodisiaque.
