I am a relatively new to brewing only about 7 batches in all different from ipa to stouts to witbeir. One thing I have noticed I'd that different company's recipes tell u different things when it comes to steeping like get the water to 170 steep for 15 min with burner off another is get water to 155 and steep for 25 min. So what is the general rule of thumb for this all being extract kits
