I have been trying to nail down a few different brews. Saison, bitter, and braggot. With the saison, I brewed one which hit all the spots for me. Earthy, spicey, some fruit, and a nice noble hop aroma.,as well as low gravity. I used four different yeasts in no measured proportions, and have not been able to duplicate.
Bitter- still searching. Looking for that Burton snatch, and nice big EKG aroma, or Fuggles. Just haven't found the balence I am looking for without making it an esb.
Braggot - not even sure quite what I am looking for. But I brew them a lot, and have a different concept for each one that is just not quite met.
4 different yeasts will be hard to replicate. Bitter is a great one to seek excellence on - recipe, mash temp and hop rate can make it elusive...I love to try to replicate Marston's Pedigree (I've gotten close, but it's just not the same as cask-served with a beer engine and sparkler). Braggot is an area in which I have yet to delve - but you may just find what you like even without being certain what you are looking for!
