The K6 Gold Complete Beer Equipment Kit (K6p) Premium includes all the conveniences you get with the K3 kit, an adhesive thermometer for the primary fermenter, and a full 27-page beginner’s guide. But the K6 has a 7.8 gallon bottling bucket and a 6 gallon glass carboy (contrast two, 6.5 gallon buckets in the K3). The 6 gallon glass carboy is good for secondary fermentations, but is big enough to house primary fermentation of a standard 5 gallon batch. The 7.8 gallon bucket is perfect for bottling, and is also a great choice for primary fermentation. Moreover, with these larger-capacity containers, it’s possible to brew up to 6 gallons in a single batch. The Kit includes: 7.8 Gallon Bucket with Drilled and Grommeted Lid, 6 Gallon Glass Carboy with Rubber Stopper, 3-Piece Airlock, Adhesive Thermometer (for Fermenting Bucket) Stainless Racking Cane, 5′ of flexible tubing, Dual Function Bottle Filler (3/8″ OD) Bottling Spigot for Bucket, Triple Scale Hydrometer Twin-lever Capper Beer Bottle Brush, Two 4 ounce Easy Clean Cleanser, HandCraft Brewing Guide Beer Equipment Kit Instructions. This kit also includes a Stainless Spoon, Bucket Clip Shut Off Clamp and Carboy Handle.
