Can I recommend this podcast from the Hombrew Club https://open.spotify.com/episode/6J...i=3roDRCZzQ3mY_gQTebtDIg&utm_source=copy-linkOh yeah, WLP 002 is the Fullers Strain. It doesn't attenuate very well, but it has a wonderful character. I actually added a little bit of brown sugar to hit my numbers. WLP 004 I believe is the Guiness Strain. I had a Porter recipe that I played around with, and that yeast was the final step in making it really good.
I remember Martin Keen saying he sours a portion of his wort and adds it back to his keg to create that "authentic " Guiness flavour.
Love your dedication man!
