Dingle-Dick Mack's is a great brewery/bar to stop at. The brewery is technically separate from the bar (run by different people, but it's right behind it). Didn't have a chance to see the brewery, but they have some pics at their site below. The pub is the classic irish pub-half a dozen small rooms with comfortable furniture. The beer was pretty good, they had a nice coffee stout, red ale, and IPA (West Coast). Their pale ale fell a bit short, it was a little vegetal. They also had a huge selection of Irish whiskey, especially the nearby Dingle Distillery. https://www.dickmackspub.com/
Dingle Distillery was a great stop. They offer a tour for $15 euros (~$17 USD), which includes a full pour of either their vodka or gin and a whiskey. I had the batch 3, finished in bourbon and port barrels. Some nice vanilla and some nice chewy/toffee/dark fruit flavor. The gin and vodka both start as wheat based neutral grain spirits (NGS) from Germany, and are distilled one more time on site. The gin is a nice London style, chill filtered. The whiskey is made completely on site, mashed and fermented in giant wood foeders. No temp control apart from "Open lid to cool" or "Close lid to heat", but it's fairly chilly there. http://
Pubs typically had Carlsberg and Guinness products (Guinness, Citra IPA, and Hophouse Lager). 5 Lamps in Dublin makes a nice Czech lager (located just south of St. Stephens Green area). Kinnegar Rye IPA was ok, if a bit sediment-y. Finnadork had a nice bourbon barrel aged brown ale. Craft beer you typically can buy from grocery stores for ~2.50-3.75 euros per bottle. Smaller stores have mostly Guinness products and Jameson/Bushmills/Powers for whiskey.
