I say, if he insists on going to the brewery, STAY HOME! Don't go on the trip at all!
He's not likely to pick you up and drag you out the door!
If he pressures you, point out that you'll be saving him money.
Right now your sobriety and sanity are a higher priority than spoiling a meal for your family.
If he wants to take the kids to breweries to eat, he can jolly well go without you.
You don't have to be argumentative: just tell him sweetly that you're sorry, but you wouldn't be capable of limiting your intake, so it'd be best if you just sat things out until you were stronger.
Maybe next trip!
