The Wellington in Birmingham, England features an impressive 16 cask ales that are forever changing. They do a great job of informing people when the beers change and you can view a live list of their beers on their website. You can read a review of the pub on Travels with Beer.

Behind the bar at the City Arms, a redeveloped Brains pub that provides one of the best selections of ale and foreign beers in Cardiff. You can read a review of the pub on Travels with Beer.

Barrels and brewing equipment at Great Divide in Denver, Colorado. Notice that yeti sticker? Oak aged Yeti is a fantastic beer.

This is a site every beer drinker wants to see when walking into a pub. As well as the 8 casks of ale they also sold La Chouffe, Mort Subite, Kuppers Kolsch, Zot, Rothaus and Moravka. On top of that they also have a great selection of bottles. Read a review of the Cask over on Travels with Beer.

A pint of Tomos Watkin's Worms Head Ale at the Helvetia Bar inside the Worms Head Hotel in Rhossili, Swansea.

Yum. I think the photo says it all. Taken at Lock Stock & Barrel in Newbury.

Gotta keep that beer cool. Some Brooklyn Pennant sits on the bar at the Tap and Mallet.

Brains beer lineup at Terra Nova in Cardiff Bay, Wales. These are some of the best beers out there in my opinion. I especially love the Brains Dark.

The Jerusalem Tavern is St. Peter's London pub and it happens to be one of my favorite pubs in London as well. Only open Monday-Friday. Be sure to grab some Tyrrells chips while you are there. Best chips ever. What is your favorite St. Peter's beer? I favor the Ruby Red Ale.

Very active cask of Rohrbach's Stock Ale at the Flour City Brewfest. It tasted as refreshing as it looks.
