Tonight is the biggest night of Savor week, with two dozen tastings, tappings and events on the official Savor calendar. It's a really difficult task to trim the list down to a few essentials, but here are the ones where we'd spend our money.

Sister bars Scion and Crios are hosting the second Night of Extraordinary Ales on P Street NW, with 40 beers from 21st Amendment, Deschutes, Oakshire, Revolution, Sun King, Surly, Uinta and Victory on draft and in bottles. Of those brewers, only 21st Amendment, Uinta and Victory regularly make it to Washington. Just be warned that Scion's narrow bar gets very crowded. Here's the full tap and bottle list.

Twenty taps at Ballston's Rustico are being turned over to Richmond's Hardywood Park and Tampa's Cigar City breweries today. Hardywood is an up-and-coming brewery known for Belgian-style ales with funky aging techniques; Cigar City has a cult following for its IPAs, farmhouse saisons and imperial stouts. Cigar City beers are rare in these parts, which makes a chance to drink the Double Barrel Aged Hunahpu (an imperial stout with a perfect rating on Beer Advocate) and Jai Alai IPA a good reason to go to Ballston, beginning at 4 p.m. Click to see the beer menu.

Jim Koch, the founder of Sam Adams, hosts a party at Jack Rose dedicated to the 30th anniversary of America's largest craft brewery. Twenty Sam Adams beers will be on tap (and $5 from 6 to 9 p.m.), and everyone who buys a beer can partake of a free clambake from 6 to 8.

Minnesota's Surly Brewing Company has lots of fans, thanks to beers like the dry, hoppy Overrated West Coast Style IPA and the amazing Furious IPA. They'll pour 13 beers at ChurchKey tonight, including Schadenfreude Dunkel and Pentagram wild ale, and casks of Furious and Blakkr, a dark ale, beginning at 4 p.m. You might want to go on the early side: A Surly event at Pizzeria Paradiso during last year's Craft Brewers Conference ran out of beer pretty fast.

One of the best brewery-vs-brewery events returns to Birreria Paradiso in Georgetown tonight: Washington vs. Washington. Eight taps will be devoted to beers from Washington State's Elysian, NoLi, Reuben’s Brew and Sound Brewery, while eight more will go to D.C.'s own DC Brau, Atlas and 3 Stars.
