I'm in a unique position that I have my Brewing and Wine making license. At my shop I typically keep 6-8 beers on. So no longer are my beers "Home Brew", but I still brew them.
I like that I always have a variety to pick from just from what I have on tap at the shop.
That being said, there are always certain seasonals and beers that I don't brew that are a treat to get.
Also, trying others beers can spark ideas and help in your own development. Its amazing the amount of creativity there is out there, some good, some bad, but creative none the less.
Remember, variety is the spice of life!
Cheers,
Brian
