Home brewed hard seltzer is a little more complex than carbonated water with alcohol and flavor added. Unlike commercial hard seltzers, home brewed seltzers have a bit of character from the yeast fermentation than can complement the natural flavor and add a bit more dimension to the flavor.

We designed William’s Hard Seltzer kits both to save you money and put you in control – you control the alcohol level between 3.8% and 5.8%, and in doing so control the intensity of the additional flavors added by the yeast fermentation. As our blind taste tests showed no difference in flavor between seltzers brewed with corn and store bought cane or beet sugar, we left the sugar out, so you can source your sugar locally. This has the added advantage of dropping the cost, and you can make Seltzer for as little as $2.20 a six pack with our kit and your grocery store sugar.

We sourced our natural liquid flavors from a leading supplier of craft beer flavorings, and test brewed dosages to determine a flavor level that is perceptible without being cloying or overwhelming. For yeast, we picked the clean fermenting Lalvin EC-1118 Champagne Yeast, a rugged yeast that leaves very few flavors, and settles out completely to eliminate the need for filtering. To assist the yeast in fermenting the nutrient-free sugar base, we have included a generous amount of blended yeast nutrient.

Easy to make with home brewing equipment, click on the instruction link below for the brewing procedure. Makes 5 gallons with a starting gravity of 1.035 to 1.048 depending on how much sugar you use.

Raspberry hard seltzer not so great

Review by Albert Irusta on 3/31/2022

I brewed the raspberry hard seltzer kit using 5 lb. of beet sugar which gave me a starting gravity of 1.043. At bottling the final gravity was 0.993 and the seltzer had a very strong sulphur odor. After about 18 days I opened the 1st bottle - still strong sulphur smell and very little raspberry taste. After several more weeks the sulphur odor dissipated somewhat but still very little Raspberry flavor. I also bought the black cherry kit, I will cut back the sugar to 4 lb. and see if that reduces the sulphur odor for that kit. William's Brewing Responds: The sulphur odor is from natural yeast carbonation, which will dissapate over time, particularly if you age your bottled seltzer under refrigeration. To completely eliminate the sulphur component, keg your seltzer and carbonate with C02.

Q: The seltzer itself taste great, but it has an extremely yeasty- almost kumbucha like smell. Anyway to correct this?

A: Yes, keg the seltzer in a kegging system. You can also use something simpler like a I12 Growler with a pressure cap G34 and a C02 regulator like our item D61 to make a relatively inexpensive C02 dispense system. Or get something like our 5 Gallon Beverage System B62 for a full sized system.
