I did a split batch of this against OYL-016 Fuller's, using the same English Brown wort, identical fermentors, and 68°F constant fermentation temp. These strains have a lot in common. They both fermented out with virtually identical kinetics and finished at similar terminal gravities with the Tim Taylor strain finishing exactly 1 point lower at 1.011.
It's hard to beat Fuller's legendary flocculation - drops like a rock even at RT right after fermentation, but I found the Tim Taylor strain also floccs very nicely and was virtually clear after less than a week in the keg at serving temps.
The ester profile is virtually the same, just more fermentation character overall with the Fuller's where the Tim Taylor is notably cleaner, but I am guessing you could largely erase these differences by fermenting the Tim Taylor strain hotter (eg 70°F vs 68°F) and vice versa, dropping the Fuller's a couple degrees.
The most interesting thing was how each strain differentially highlighted different aspects of the same malt bill. The Fuller's beer consistently came across as more nutty with a very slight acidity, and the Tim Taylor, more carameley and malty-sweet which I highly enjoyed. Even the chocolate notes tasted different. It was like I brewed with two different malt bills. The Fuller's would be my choice to put into a competition, more traditional, but I found myself actually drinking the Tim Taylor variant more.
The kegs emptied themselves quickly to the point where I had to force myself to bottle them early so I would have enough bottles to distribute to Bobby, the Garden State Homebrewers, and put into comps. I found myself flip flopping my preferences almost every single time I tasted these, but I will say, both of these definitely have a place and I will be brewing with both of them again. Right now I have just tapped my first English Porter and I used the Fuller's strain at that lower temperature, and, well, it's another immaculate English beer and throwing down a couple pints is effortless. I plan to either re-brew the Brown next fermenting with the Tim Taylor strain at 70°F, or try it in an Ordinary or Best Bitter where I feel it would really shine.
Both of these strains kick S-04 to the curb. S-04 has made some fantastic beers for me and I love it and it's a great value, but these are worth the money. I feel like anything you could want from S-04, OYL-14, this Tim Taylor strain can do it better. It has the velvetey smooth mouthfeel like Fuller's but finishes dry, crisp, and clean like S-04.
