Check the colour of this brew! Looks like mango juice straight up, opaque with no visible carbonation, zero head nothing but juice appearance. On the nose it's actually quite sour, usually it's more fruity with these Goat brews. Go reaching in with your snout though and you can pick up the soft mango, sharp passionfruit and the placebo scent of chilli. I know it's I'm there so I think I can smell it! Really it's more of a winter spice sort of tinge. Ooh yep, that's sour. Not the most extreme I've had from them but decently mouth puckering. You're hit by fizz too then sweet juice. Second sip and the sour hit is mostly gone, the fizz burns fast and brightly like a candy more than the steady fizz of a champagne or lager. It's got a clean but sweet finish and the masses of real mango and passionfruit are obviously the culprit. Thankfully I'm not getting hit with chilli, it's more a suggestion, a subtle complexity beneath the wealth of juice. I am left with a strange dry yet coated tongue. Smokeyness is more apparent than out right chilli, despite the three kinds used in this Collab with Northern Monk. It does slowly accumulate though and it's on the tongue as an aftertaste and sensational as opposed to explicit flavour. This is the way to do it, you don't actually wanna drink chilli do you. It's morish via the juice, the sweet and sour richness of flavour. I've had a few mango sours and this is the best to date, that I can recall. Yes, passionfruit stands out more but the marriage of mango and passionfruit is a tried and proven one. And all this sitting on top of the base golden sour, as it were. Of which is tropical and stone fruit to begin with. I recently reviewed one actually, aged golden sour with no fruit and it was impressively fruity. But this obviously tops it on the fruit front having been juiced up thoroughly. (The chilli is building more now, quite noticeable on the tongue) It's a great brew. For fans of heavily fruited mixed fermentation sours.
