I'll be in touch, I'd really be keen to try the Balcones. Very generous of you!
Thanks for the heads up that Torfa is a good replacement for Longrow, might be useful down the line and this is the second time I've heard good things about it. I'm going to wait until a whisky tasting event to try the other two but I've been very tempted by Revival, it just always ends up slipping down my next purchase list.
If you're in jhb go through to Bottega and have a taste. They also have the Glenglassaugh Octaves Peated which you can taste while you're there.
