You can show your appreciation for Wine and everyone that makes it possible by donating to the Wine Development Fund. Your donation will go towards paying for things like developer conferences (such as WineConf), supplies, and documentation.
All of our donations are managed by the Software Freedom Conservancy, which is a 501(c)(3) organization so donations can qualify as deductible under the American tax code. If you have any questions or need further assistance, please visit the SFC site.
Donate to the Wine Development Fund by cash, cheque, or international money order in US dollars. All mailed donations should be sent to the Wine project in care of the Software Freedom Conservancy at:Wine Project
