Mom is unhappy - feelings discouraged

I’m mostly here to vent but would accept any opinions/advice on the situation.

So so one of the hardest decisions we’ve made so far with planning is where or not to serve alcohol. We originally intended for it to be dry for budget reasons and because we have a lot of coworkers/bosses and religious family members attending and my dad is a recovering alcoholic. This literally kept me up at night trying to decide what to do but in the end we have decided to serve beer and wine. Because the other half of our guest list is people like us, our age, that like to drink socially. We decided that because we are the type of people to drink when we go out, it seemed more “us” to have drinks and celebrate.

Well, my mom is pitching a fit. She hates alcohol. She asked me today if I was doing beer and wine and I said yes and she goes “that’s so stupid! Well then you don’t need nanny (my grandma) to say a prayer during your ceremony!” Honestly let me say that I love my mom and we are close and usually she is right. So I’m struggling with this because I also know that she can be judgmental and I know that even though I love Jesus, I don’t think I’m going to hell for drinking on occasion. I’m just disheartened because I hate disappointing her (even at 25 years old🙄) and I don’t want to listen to her negative comments. Has anyone else been in this situation? Did your mom/family member get over it? I just want her to let me decide how I want MY wedding to go - especially because I’m grown and I’m paying for it.😕
