VitiSynth is a claimed “open access” database for wine and grape professionals. The site foregrounds recent research, and does an interesting auto-highlighting of industry-specific terms and details in research abstracts…

Also does auto-translation to English of Spanish abstracts etc.

There’s no RSS, though. And the website’s “open access” sub-title is rather misleading. The website is public, but the research being linked to is often pay-walled and there’s no “Open Access research only” filter for results.
