It turned out fairly well. I made it primarily for my wife and she loves it. Though I was worried about the fermentation. I did not see a lot of bubbling from the air lock. I added the yeast nutrients as directed, but I thought maybe the yeast was bad. After 2 weeks, I tested the ABV and it was around 3.75%. I felt this was low, so I bought additional yeast and yeast nutrients, but decided to wait another two weeks. After 4 weeks the ABV was around 4.8%. This was good enough, so i did not add any extra yeast or nutrients. I added half of the lemon flavoring that came with the kit and bought liquid blueberry flavoring, and added 1/4 of the bottle and kegged it. After about a week, we tried it. I get a yeasty flavor, like fresh baked bread. Certainly not a bad flavor, but I couldn't taste the lemon or blueberry. My wife liked it, but she suggested adding the rest of the blueberry flavoring. I did and we tried it again. She said it was great, but I still get the yeasty notes more that the fruit, but I like strong IPA's and heavily peated scotches, so that might just be me. It's a very simple boil, but there is the extra steps of adding the yeast nutrients. I give it 4 stars and recommend it to anyone that likes a selzer. It is definitely cheaper to make than to buy commercial ones. I also considered adding flavored vodka to it to boost the ABV and to add additional flavor since I have a keg system. ENJOY!!
