As the oldest standing Major League ballpark, many baseball fans regardless of rooting interest make a pilgrimmage to take in a game in the shadow of The Green Monster at Fenway Park. The ability to grab a great beer while taking in said game would be a nice bonus, but that's not why you go to a game there. Which is a good thing.
First, there's one thing not on the map. If you enter on Yawkey Way, you present your ticket and go through security on the blocked-off street, before you get to the gate. There are a number of food and drink and memorabilia vendors that are "inside" without actually being inside the park. On Yawkey, I spotted a stand selling Harpoon IPA on draught. Harpoon will be available in a handful of locations throughout the stadium, but this is the only location I saw it on tap. From there, you can enter the actual stadium at which point the map becomes appropriate:
The red dots are approximately where craft offerings (including Goose Island) are available. The yellow dots are where not-quite-craft-but-if-you're-in-a-hurry-you-might-be-tempted offerings are available. Specifically, near Bleacher sections 39-41 I saw Shock Top and near Grandstand Sections 6-7 was Blue Moon.
The booth behind Grandstand 21 had the standbys of Goose Island 312, Guinness, Smithwicks, Harp and Narragansett Lager, which all feel a bit iffy to throw under the craft umbrella, but there's gotta be some sort of content here, and based on the numbers alone these are by far the best options in the park. As far as I saw, this was the only place to get any of the Guinness products.
Outside of that, the rest of the spots had some combination of Sam Adams Summer, Goose Island Honker's Ale, Stella Artois, and cans of Harpoon IPA and Harpoon Summer. Exceptions to this were the 302 Bar behind Grandstand 7 and 8, which carried only Long Trail Ale, and a stand behind Grandstand 3-4 carrying Wachusett's Green Monsta IPA. This was the only place I could find Green Monsta, which was surprising to me. Did I miss a spot? It seems like this should be more readily available.
There was also one mystery stand called the Canvas Alley Bar behind Grandstand 12 or so that wasn't open either night I was there, but a sign posted outside the window had pricing for "Premium Beer" and Gluten Free Beer. (Anyone know what's there? Post it in the comments!) I wasn't able to get into the area atop the Monster without a very expensive ticket, but from the entryway to the section I didn't see any vendors there. As for pricing, 12oz Harpoon Cans were 9.25, and pretty much all other things craft or close to it were in the $9-10 range for a glass.
So, for the final scorecard:
Fenway Park, Boston Massachusetts: 74/100.
Excellent stands: none, unless you count the Guinness stand, but "Oh, that'll do" type of stands are readily available.
