I think it is lovely that you are choosing to honour your FIL this way and create a good memory for him. I have noticed a few comments that suggest you should serve what you wish and not let your FIL dictate things, but this does not sound like something he is dictating, but something you choose to do. It is more important to make your 88 year FIL happy than serve beer, so go ahead. I (who love an afternoon beer) wouldn't say boo.
Whether anyone else will bring or ask is up to your circle. I usually bring wine as a hostess gift and would likely bring it after a first communion (as someone else said, they have wine in the ceremony), but would be just fine if the hostess said "Oh thank-you, we're not serving wine, but we can enjoy this when you come by for dinner next" (or at a later date)
