Open Fermentation.

Stumbled across this thread while searching.

Thought I'd post to share a blog from Australia's Wildflower Brewing discussingthe use of wide, flat (open?) vessels for fermentation (link: https://wildflowerbeer.com/blogs/blog/process-e1-primary-fermentation-geometry). They intended to use the vessel to promote ester formation in their semi-wild brews.

The brew in Australia and don't have temp control (so plenty of esters I'd imagine!).

Definitely a route I'm tempted to go down.

[edit:] not sure how much difference it's likely to make at the homebrew scale though...

I wondered too, so asked in a twitter conversation. A brewing and distilling Professor from Heriot Watt University replied that it does and had students working on it.
