I didn't realize the failure rate was that high, though.
Well, remember, any given Sunday.
Some of the gins we tasted blind were actually successful---in that they were being sold and had gotten some decent reviews and accolades. We were tasting them straight, at room temperature, and alone. And quite a few of them.
Yes, it disconcerted all the judges (some professionals with international credentials and knowledge, some local distillers, some bartenders) that there were so many poor gins (and even worse, poorly made gins).
The worst, I found out subsequently, were 'one off' experiments, distillers playing around with a single batch of something wild (and as often as not, based on what I tasted, things strange and ugly)----and then bottling that batch for sale in their tasting room when it was evident it wasn't going to go any further. You just don't do that if you value your reputation and your desired brand equity!
Keep in mind also that it is not at all unusual for a distiller to submit a spirit specifically to get feedback to see if it has legs. Many of these, sadly, were entirely without support and belonged in the thalidomide category. Uck. Just because it is a botanical doesn't mean you should distill it into gin.
