I've never tasted Screwball. To my knowledge I've never tasted a peanut butter flavored whiskey. I am not a fan of flavored whiskeys as a general rule. I purchased this on a lark, a 50 ml bottled just to see if I've been missing anything. Have I? The nose is roasted peanuts in a sweet syrup. It smells nice but it's not complex at all. There's really nothing there except for the smell of roasted peanuts. On the palate this is sweet with a very silky mouthfeel. The flavor is sweetened peanuts with a little touch of something spicy at the back end. I wouldn't be able to tell you it was whiskey if I didn't know it was whiskey. I have no idea how any human being could actually drink this by itself. This is clearly not meant to be sipped neat from a glencairn. I honestly don't even want to put it on ice, but I imagine if I put some bourbon cream in this it would taste like a peanut butter cup. That would make lots of inexperienced and immature drinkers quite happy. At least until they throw up on themselves. This is definitely not my jam. Given my own devices I would rate this a one star, but that's not fair. It probably is what it's advertised to be, I would just never buy that product. So I'm going to say this is as average as average can be. I award it 2 stars and that's a gift. This is a liqueur, it is not a whiskey. This is 1980s cocktail bar sweet drinks Disco era nonsense. This is either a mixer to add sweetness and flavor, or a chilled shooter for those who have no idea how to enjoy whiskey. I'll pass. Anyone want the 25ml left in the bottle? I couldn't finish it.
