I have brewed dozens of their beer kits with great success, however these seltzer kits are trash. I ordered four kits and brewed the first kit per the instructions but did not take any specific gravity measurements assuming it would land somewhat close to the desired ABV like any other kit I received from them in the past. The first batch was a raspberry and like many reviews the flavor was almost nonexistent and tasted like dead yeast. I suspected the ABV was very low but couldn’t be sure without any measurements, that’s on me. Fast forward to the second batch, I brewed exactly to the instructions, fermented in a warmer environment (70 degrees Fahrenheit) added yeast nutrient as instructed. Today was week 5 (I gave one week extra to help the dead yeast settle out) and about to keg the batch I checked my gravity and realized it had barely fermented. OG 1.034 down to 1.026 = 1.05% ABV. Also, out of the four kits, at least one yeast packet was expired by six months. I did not check the date on the first batch but I assumed that was expired as well and resulted in the low ABV and yeast flavor.This second batch I ensured the y east was not expired and rehydrated it per the yeast instructions but still failed to ferment. I have pitched another yeast packet (from my 3rd kit) to see if this will finish fermentation before dumping it down the drain. If the additional yeast does work, I will need to order two more yeast packets and additional flavoring for the remaining kits. I have already purchased additional flavoring for the current batch, if it ever gets beyond sugar water stage. In closing, save your money, buy your wife’s hard seltzer elsewhere and continue brewing your exceptional beers like I wish to had. Good luck and happy home brewing. I would give zero stars if possible but the 1 star reviews don’t even appear. 🤷‍♂️

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!!
