As of Sept. 1, all breweries in Texas will be allowed to sell packaged beer on-site, regardless of their license, thanks to a new state law that takes effect. Until now, Texas was the only state in the country to prohibit to-go sales at manufacturing breweries. The new law will allow consumers to walk away with up to one case of 12-ounce bottles or cans, or 288 ounces, per day from a brewery. Some breweries with a brewpub license already had the ability to sell beer to-go. Here are some local breweries inside the Loop that are marking the brewery business milestone on Sept. 1 with specials and events. Holler Brewing Co., 2206 Edwards St. Suite A, is hosting Extravacanza, complete with the brewery's first-ever can sales and Eddie O’s BBQ starting at 10 a.m. www.hollerbeer.com Eureka Heights Brewing Co., 941 W. 18th St., Houston, which had a brewpub license, is still celebrating with a buy-three, get-one deal on six-packs all day. www.eurekaheights.com Buffalo Bayou Brewing Co., 5301 Nolda St., Houston, is hosting "Buff Brew ...to Go", a party at their taproom from 11 a.m. to 6 p.m. where they will sell cans of Crush City, More Cowbell, Dreamsicle, Sam’s Daily, 1836 and Smoke on the Bayou.
