I am planning to brew a hefeweizen for my first time Tomorrow and need information regarding fermentation. The recipe calls for the temp to be between 60 and 72 but my unfinished basement is currently reading 54 to 58 degrees. Will this affect the end product my beer? Will fermentation take longer to complete? If it's too cool, what can I do keep the temp in the correct range? Lastly, thoughts on whether to rehydrate the yeast or pitching directly to wort? Thanks for the help.
