Notes From Brad - Head Development Brewer:

Hard seltzer waters are all the rage these days, so why not ride the wave? This kit is a very simple and straightforward fermentation consisting only of dextrose (corn sugar). The resulting product is boozy water, coming in right at about 5.5% ABV and is then flavored with all-natural crystallized grapefruit powder. To ensure the best results with this kit, be sure to follow the directions and add the yeast nutrient packets according to the schedule described. Adding yeast nutrients in staggered additions ensures that the yeast remain happy and healthy and will avoid any off-flavors that stressed out yeast can generate. The fermentation will be complete within 2 weeks or so, but be sure to leave this batch sit for a few additional weeks to allow the yeast to drop out of solution and leave behind a clear beverage. We have also included three separate packets of the flavoring, so you can decide how intense to make the flavor - add a little at a time and taste until you are happy with the flavor level.

A wise choice

I allowed the fermentation process to take the full 4 weeks as recommended. The results however are delicious. I decided to keg my seltzer for more controlled carbonation. I’d highly recommend this if you have a bit of patience.

Seltzer Rocks

I have gone through 3 of theses kits with kids home from College due to COVID-19 DO NOT JUDGE! Great flavor, easy to make and recommend force carbonation via keg for best results. If sporty add an additional lb of corn sugar and one more 1.5 grams of yeast nutrient during primary on same sked. Should yield around a 6% abv. Just sayin

First Time Hard Seltzer Brewer

I'm just 2 weeks into the first batch, but so far it's a much different fermentation activity than Red wines. Just not a lot of activity comparatively. I did do a secondary fermentation. Now waiting out two more weeks til bottling. Will keep you advised.
