Having a nice pour in a FR glass I got this fall at the distillery gift shop, and I'm loving this glass. Square on the bottom, round on the top, with "creases" in the corners. Easy to hold, and those "creases" are great for getting those last precious drops out. It was pictured on the old FR website, but I don't see any pics of it on the revamped site.
They told me at the shop that they didn't have any more, the display model was the last one. But one of the sweet gals at the shop went out back and found two for me. Don't know if they've truly been discontinued, but if you're at the FR gift shop, see if they can find you one. It's a real nice glass.
