Craft Seltzer Kit

"The seltzer yeast from Propagate laudably performed. We brewed multiple full sized commercial batches with reliable fermentation kinetics and excellent sensory on the final product. Subsequent generations were harvest-able, stably fermented, and out-classed several other seltzer yeasts head-to-head” 

-Adil, BeerLab!-

Ferments a simple sugar based "wort" from 1.060 to 0.995 SG within 7 days. Produces a seltzer with subtle wine notes that is intended to be a clean slate for flavor additions.

We just filtered and transferred the seltzer to the brite and it is amazing. It is a really solid seltzer and we are very excited about it. You guys have a great product.

They turned out really well, thank you for your help.  They are also being received really well by our customers, win.  Thank you again.


Andrew, Flatland Brewing

We made that one batch and split it between 2 flavors, a White Linen cocktail (cucumber, lime, elderberry) and a Tropical version with Kool Aid Packets. Both are killer.
