Thank you for your enquiry to the CWSA - the biggest and most prestigious wine and spirits competition in Hong Kong and China. Also, thank you for your interest in organic/bio production.
The CWSA Bio is open to certified wines and spirits only. The full list of the many certifications that are accepted is here...http://www.cwsa.org/cwsa-bio/
If your wines/spirits are not yet certified you are welcome to enter your wines to the CWSA (which is open to non organic/bio wines). The key dates for your diary are kept uptodate on www.cwsa.org and it is time to enter your products now for the forthcoming CWSA competition http://www.cwsa.org/enter/
Wishing you great success at the CWSA and looking forward to seeing your samples.
Very best wishes,
