My complaint:
Took last sip of beer to hear something rattle around in the bottom of the can. Appeared to be a white solid cylindrical in shape. Thought the beer may have started to freeze solid as it was 0% variety. Tipped it upside down to melt and drain out before I but it in the trash. Next morning I went to throw it out and still heard the rattle in the bottom of the can. Thinking something had gotten dropped / inserted into the can I removed the mouth ‘flange / tab’ in an attempt to remove the object but it was too large to come thru the opening and likewise would have been too large to drop or be inserted into the can after opening.
Likely the object was in the can during the ‘bottling’ process.
Suggested solution:
Determine who, where, or what, the object was and how it got into the can and assure that their bottling equipment isn't allowing tainted objects to comingle with what should be a sanitary, ingestible, drink.
