What point in ceremony to do wine blending??

My fiancé and I are getting married at a winery so it seems pretty fitting to include a wine blending unity ceremony. When I google it tho, I find tons of sample scripts for the ceremony and all the meaning behind it but not when it's supposed to be performed. I googled when to do unity ceremony and most sites recommend AFTER the I Dos. In my head we do unity first, then we say our personal vows, then I dos, then kiss the bride and woohoo we're married! Do you think it would be weird to do the unity ceremony before the vows? Because to me it seems kind of weird to do the vows/I dos and then take a break to drink wine before kissing and being introduced as Mr and Mrs lol. Help please 😂
