Notes

The variety of base malts (2 row, pils) were cobbled together from what we had in inventory. I would rather use Maris Otter but need to clear out our older malts collecting dust. Will nitro all of the product. We had a small amount of Norther Brewer laying around as well so will utilize it.

Ended up with 4 slims so I put three on Nitro and one on our beer engine. Will taste in the coming days. (Above notes related to version 1, changes below).

Note: This is version 2. Base malt is now Maris Otter (from a mix of 2 row/Pils). Also has a bit of oats added to make up for the ~1 lbs shortfall in Flaked Barley that we had on hand.

The Name: Back in the 80's an Irish bartender friend of mine was recounting (over a Guinness) a protest he was participating in in Dublin years ago. The Gardai started chasing after him and to get away "Aye Matt, I had to take a dip in the Liffey" referring to him jumping into the river to get away, which he did.

This stout was brewed on our 1 BBL pilot unit at New Magnolia Brewing in Houston, TX. My aim was a middle of the fairway dry Irish Stout. And that is exactly what came out. I ended up with a total of 4 slims, 3 were nitro'd and 1 was for our beer engine. Nice notes of roast and dark malt forward flavors. Nice, creamy mouth feel from the nitro/beer engine enhanced by the flaked barley. The only thing I would change is I would increase the bitterness. Like a lot of our pilot brews, we raid the cupboard for ingredients. The Northern Brewer hops was from crop year 22 so I think they came off a bit short in terms of predicted bitterness (if Ih had to guess, I think it landed in mid 20s). I think another 10 IBUs or so would have been better. We had some spare 2 row but not enough so we had some extra pilsner malt I added for the base malts. Would rather have used 100% maris otter. Given the hodgepodge/dated make up of the ingredients, this turned out to be a very solid brew. Give it a 4.2.
