This brisket marinade is made with Guinness Extra Stout. The hops of the beer add a unique flavor and bitterness, while the remaining unfermented malt sugars add sweetness.
Mix ingredients well, making sure that the sugar is completely dissolved. Pour the marinade over the brisket in a large pan and refrigerate, turning it often so both sides get marinated. Or better, put the brisket and the marinade in a large plastic bag, turning it every hour.
If you have a marinade injector, pump about one cup of the marinade into the brisket, spaced evenly. Marinate the brisket overnight for the best flavor.
Use apple or another light flavored wood so the flavors of the marinade will come through.
Irish Dipping Sauce
Try this excellent dipping sauce, developed especially for brisket marinated Irish Style!
Mix this brisket dip up BEFORE all the Guinness is gone! Make this two hours before serving, so the flavors have time to blend.
If you still have the remaining four unopened bottles of Guinness, serve them with the brisket, so everyone can toast the pitmaster!
