My wife wanted me to wait to do this one for Christmas, but i didn't want it to sit in my fridge that long. Frostie has been around a while also. I couldn't find an official site, but the source of all truth says that Frostie was started in 1939 and is currently being produced in Temple, TX. This one was actually recommended to me by a guy i work with also. Frostie also produces many other flavors which can be found for sale on several websites. Not sure how easy it is to find this stuff in stores around the country.
This root beer also comes in a clear bottle, which is pretty standard in size and shape. It also has the Frostie logo embossed on the bottle (like IBC) around the top of the bottle before it gets to the neck. The clear sticker label shows a little Santa Claus looking guy on it and a snowy scene with a mug of root beer. It looks like it would be a holiday drink, but really there is nothing particularly "Christmasy" about it.
It's not bad, but there's really nothing special to this stuff. I liked it, it has a subtle wintergreen flavor and a very light vanilla/creamy aftertaste, but all in all it's just kind of a standard root beer. I have heard from other review sites that it is not what it was "back in the day", and it kind of universally has the reputation of being an average root beer. Sadly, i have to agree with these nobs.
My official review is that Frostie gets 6 (six) IBC. I like the wintergreen in it and it's a decent root beer, but nothing particularly stands out about it. I wouldn't make a trip just for the Christmas aspect of it. I'd think Dad's or Jack Black's taste more like the holiday spirit. But i am not sure Frostie was even trying to allude to reminding you of Christmas. Well what's with Santa on your bottles then? Anyway, it's not a bad root beer. Try it if you get a chance. Or don't. I don't care.
