Summit cola zero weird taste

I just bought four 12 packs of summit cola zero sugar today and they taste off. I’ve been drinking this soda for a while now and never had any problems. I can’t stand the taste of these and I even bought a pack for my mom who JUST tried it the other day from an older batch and really liked it. I’m so sad. I’m going to return them and hope they have some from a different batch.

I’m wondering if anyone else is experiencing this problem.

Batch number: Either 060808B2C022 or NC13:456

Expiration date: 2/10/27
