Its very common to see inconsistent results with standard tins of homebrew. You cant have the same tin of brew go all the way around the country and produce consistent, quality results in every state. What brews well in cooler climates, may not brew well where it’s warm.
Instructions, ingredients and overall quality of the brew, greatly determine how well it will work in the area in which you are brewing it. Take this into account when brewing your next brew and get the kits and ingredients that best suit your area.
