• High Quality Without The Cost – We use 100% organic tea and sugar paired with high quality supplies like fitted cotton tops to eliminate fraying (no cheap cheese cloth here!) and a US made temperature gauge, reusable tea bag and a US Made, USDA Food Grade glass brew jar.
• Just The Essentials – We designed this kit to be exactly what you need to get up and brewing kombucha quickly and easily, while ensuring you make the best tasting, healthiest kombucha out there.
• Organic SCOBY & Start Liquid – Our thick and healthy SCOBY’s are minimum half an inch thick and come with 8 oz. of potent starter liquid. Many SCOBY’s in lower cost kits online are typically half the weight or less than they should be – trust us, we’ve ordered them all. Nothing affects the quality of your kombucha more than your SCOBY and starter liquid.
• Looks and Brews Great – Don’t buy a low cost brewing kit that looks like a 4th graders science project. Our kit offers a refined look with an incredible user experience from start to finish.
• Detailed Instructions & Recipes – Our step by step instructions are complete and thorough. Unlike other bargain kits available, we don’t leave you in the dark searching elsewhere for online tutorials. We even include recipes for adding your favorite flavors
