This weekend won't be as warm as the last few days – temperatures should reach the upper 60s on Saturday and Sunday – but it should be perfect for two beer festivals.

Whether you're going to Saturday's Nationals game or not, make an effort to stop by the Justin's Cafe Block Party. The restaurant is shutting down First Street between K and L streets SE for a neighborhood gathering with live music, beer pong, a cornhole tournament and a wing-eating contest. DC Brau and Port City will each be pouring three beers, including the new DC Brau saison Seasons in the Field and Port City's Tartan Ale. Snacks come from Fojol Brothers, the Big Cheese and other food trucks. Doors open at 10 a.m. and the party runs until 9 p.m. Admission is free, and kids and pets are welcome.

In Falls Church, Mad Fox Brewing Company welcomes spring with a festival featuring 20 traditional, strong German bock beers, including three created at the brewpub. Sample versions by Virginia breweries including Devils Backbone, Blue Mountain and Legend, and as far away as North Carolina, Louisiana and Bavaria. Any four-ounce pour costs $1.50 while chefs will be whipping up German food, including bratwurst and soft pretzels. The festival will be held in front of Mad Fox's building from 11 a.m. to 6 p.m. and there's no admission charge.
