Sierra Nevada Pale Ale is a solid choice and easy to find. Founders All Day is a great session beer although has some hops.
It's pretty late for summer beers, I'd just dive into oktoberfest beers.
I haven't tried the Big Grove one but my favorite is the Millstream Oktoberfest. It just seems to have that authentic German taste or what I assume is authentic. I've tried tons of oktoberfests and that one still is my GOAT.THIS. I love hoppy beers, but tis the season for Oktoberfest beers. Sam Adams Oktoberfest is a classic. The Big Grove Marzen is one my my recent favorites.
