It's a gift, so we'll see.. should be great though!

Adds color but to age it's going to take a lot longer

I really like the idea behind this but in order to truly age whiskey it takes time. I thought this would work since it's more of a direct application, and it does add a caramel color that's attractive, but at least in the short term it adds a bit of an unpleasant bite to the Scotch. I imagine, if I leave this inside the bottle for a year, or two, I'll have an amazing bottle of scotch (I might even let it go longer just to see what happens) but in the short term I don't think this is quite as cool as it sounds.Still, it's a fun. Probably would make an awesome gift for someone like me that's willing to set it aside for a few years just to see what happens.

Makes Whisky Smoother

At the one week mark I could see a slight color change in the bourbon, and I noticed a bit of a softness in the bite or heat (the alcohol in the bourbon didn't sting so much on the way down LOL!).After 2-3 weeks, the bourbon was pretty smooth--surprisingly so, I would say. It's very easy to drink neat at this point.For reference, I was using Benchmark for this experiment--an inexpensive but still well-liked and well-rated Kentucky Bourbon.My observations are this: I like most bottles of Benchmark as is (I find that some bottles/batches are much better than others). The direct effect of this Viski charred wood insert was to make the Benchmark smoother, but I also felt that a little bit of the flavor disappeared. At the one week mark I tasted the Viski vs. the remainder of the original bottle (same exact bottle), and the Viski was a bit smoother, a bit darker, a little less burn on the way down, and had some very small black wood shavings in every sample that I poured. I guess the black shavings aren't a big deal, but it left me a little concerned. Yet I drank it LOL!After 2 plus weeks, I no longer had any of of the original Benchmark to compare the Viski batch to, but I can say definitively that the Viski is at this point very smooth. Yet I feel that a bit of the flavor is missing.So if you are a stickler for smoothness in your bourbon, this Viski is definitely the way to go. If you like all of the flavors and mouthfeel, it might still be worth a try but experiment with it on the first batch. Maybe try a pint or a half pint and compare it to the unadulterated version before going all in.

A great gift for that whiskey lover that has everything!

A unique gift for that whiskey lover! Nicely boxed and reasonably priced for gift giving. I felt it was a fair value.

Requires time

This is an interesting idea but I question the implementation.Ageing takes time and the advertised couple of weeks I find questionable.The idea is good if you take a middle grade whisky add this product, close it back upand give it a could of months or years.I wouldn't do this with good whisky.Nice gift
