CREATE TABLE beers (
	id	INTEGER	NOT NULL	PRIMARY KEY,
	brewery_id	INTEGER	NOT NULL,
	abv	REAL	NULL,
	ibu	REAL	NULL,
	name	TEXT	NOT NULL,
	style	TEXT	NULL,
	ounces	REAL	NOT NULL,
	foreign key (brewery_id) references breweries (id)
);

CREATE TABLE breweries (

### User's Query:
Which distinct state makes beer that has the least amount of bitterness?

### Extra Knowledge:

SELECT DISTINCT T2.state, T1.ibu FROM beers AS T1 INNER JOIN breweries AS T2 ON T1.brewery_id = T2.id WHERE T1.ibu IS NOT NULL AND T1.ibu = ( SELECT MIN(ibu) FROM beers )
