Catto’s is a brand owned by Inver House. On a reasonably-supported hunch, I found an older Catto’s bottling at auction. Bottle #1 [a 1970’s Catto WLP] was a write-off so I bought a second bottle. Crossed fingers.

N: Initially smells like a strange paint-like factory porridge – whatever that means to you, whoever YOU are. With only a mild maltiness, the dry earthy vegetal pepper & turpentine=paint note with lemon detergent is oddly commendable. Shame then that the youthful light grain overwhelms the even lighter malt content. A subtle pickled briny chalky-dried metallic mineral < olive brine/liquid situation ensues. Everyone will have there own take on it, but this particular bottle is never going to rock any boats.
T: Again, the grain leads the malt. Probably why then, as an old abv-low bottle, it’s stayed relatively resilient after all these decades. Edgy, paint-like and extremely porridgy as if chewing on rolled oats that are slightly honeyed and have been soaked in oat milk & >>> coppery turpentine for a few hours, enough to be succulent but dry. Other underlying descriptors of note were butter biscuits and barley sugar sweets.
F: Without an immediate urgency we see a well-tempered yet sharp green-ish turn into an underlying bitter coppery light grain-led lift-off [Canadian Club-styley]. That just leaves lingering sour-ish dry fungal coppery icing & barley sugar.

C: I’m certain there are some good examples out there. This particular bottle was neither hugely appealing nor terrible, but my investigations here [with Catto’s] are over.
