Be interesting to see how the Mangrove British Ale turns out. I'm wondering if anyone can describe the likely difference between the three. I know Gervin/Nottingham is very neutral. How would the more experience brewers describe Mauribrew? And the Mangrove? I know they are both newish yeasts on the market. And what would be your ideal yeast for this sort of recipe, either dry or liquid?
Mauri 514 is a popular, all-purpose, Australian ale yeast, almost surely derived from an English strain, which is very forgiving across a wider-than-usual temperature range. It's more estery than Gervin/Nottingham, hinting at tart green apple, pear, ripe melon, strawberry. For the same reason, it can overpower hops a bit more. It all just depends on what you're going for, but you can add a bit more late hops if you want to use this yeast for a more complex final beer.
Mangrove British Ale is probably another Whitbread-B/Whitbread-dry derivative, like WLP007, Wyeast 1098, S-04, which as you know is the original modern all-purpose English ale strain. I think all other things being equal, the continuum of neutral to extreme yeast personality would go like this:
Chico/US-05/American Ale -> Gervin/Nottingham -> Whitbread-B/S-04 -> Mauribrew 514
Of course, your mileage may vary.
