These kits use the all grain brewing process meaning that you have to mash all the grains to extract sugars as opposed to adding malt extracts to the boil. Please be sure you know what you're getting. We pick everything included in these kits at the time you order so they include the freshest stock and refrigerated hops and yeast. You will choose whether the grain is milled before shipping or if it should be left whole. The recommended yeasts for each style kit will be presented as an available accessory and if possible, you will have a choice between a Wyeast Smack Pack and a comparable dry yeast pack.
