As of this posting, Final Gravity HS has Juicy Mosaic Session IPA kits on sale. Prices start at just $19.99 for all grain and $24.99 for extract. While Supplies Last: The last time we ran a recipe sale for Final Gravity Homebrew Finds readers overran FG HS causing supply and order fulfillment havoc. To stave that off, only a limited number of kits are available at this price. Check Final Gravity Homebrew Shop for current pricing selection and availability.
