Hi there I am just getting started with home brewing. For my girlfriend's 24th birthday I am home brew with a Coopers DIY kit. She wants it to be a Blackberry Lager and I purchased blackberry brewing flavoring off of amazon to add to the fermenter. My question is when do I add the fruit flavoring to the fermenter? People have told me to add it with the malt extract and yeast but I've also heard to add it 3-4 days before bottling.
