Craft beer fads come and go, but hops will always be an essential ingredient in beer. In tribute, Mile Wide Beer Co. will play host on Saturday, Sept. 15, to the second annual Hops on the Hill.

The first event was in conjunction with National IPA Day, which is the first Thursday in August. While Mile Wide enjoyed good weather for the event, it was decided this year to push the festival back to September, making it a bit more likely the weather will cooperate temperature-wise.

In addition, Mile Wide has altered the format a bit to bring in three breweries that don’t distribute in Louisville, all from Tennessee.

The breweries — New Heights Brewing Co. and Southern Grist Brewing Co. of Nashville and Heaven & Ale Brewing Co. of Chattanooga — came to town a few weeks back to collaborate on a special release beer for Hops on the Hill. The plan for future Hops on the Hill festivals is to choose different states.

The further connection is that each of the guest breweries, as well as Mile Wide, are known for their takes on New England IPAs. The collaboration is sort of a mashup of several of those beers and is called Damgud Bucket of Greens, which is a mashup of beer names: Damguday (New Heights), Juice Buckets (Heaven & Ale) and Mixed Greens (Southern Grist).

Mile Wide co-owner Scott Shreffler said the beer will be available via draft or cans and is double dry-hopped to please all the hopheads he expects will attend. He described it as being “really soft. It’s got this really big hop flavor to it — that additional dry-hopping gives it that nice juicy hop flavor.”

In addition, several variants of the beer were created, and those will be tapped on the hour. Meanwhile, both Heaven & Ale and Southern Grist will bring additional beers for tapping.

The former will bring Boil the Ocean, a sour ale made with sea salt and tangerine, which Shreffler said is “sort of a mimosa in beer form.” Southern Grist will bring a beer called Hop Kush, a smoothie-style IPA brewed with lactose and vanilla bean.

“These are some great breweries that don’t distribute here that people maybe don’t know about,” Shreffler said.

Mile Wide’s full lineup of beers will be available, along with a new release called Blueberry Quiet Science. There will indeed be plenty of hop-forward beers on tap, but there will be choices for all palates as well.

Hops on the Hill runs from 3 p.m. to 8 p.m. on Saturday, Sept. 15. Food will be available by way of a pair of food trucks: Rick’s Bluegrass and Blues Smokin’q and Lil Cheezers.

Meanwhile, music will be provided by DJ Cat Casual. Admission is free, but a portion of the proceeds from the event via beer sales will benefit The Pete Foundation.

“We’re excited for this next step in the evolution of Hops on the Hill,” Shreffler said. “A great benefit of being a craft brewery is the collaborative spirit among breweries, and Hops on the Hill gives us the chance to celebrate this wonderful spirit.”

Mile Wide is located at 636 Barret Ave.
