With Duluth Homebrew Supply closing where you get your beer, wine, and everything else making supplies matters. You can always go to Amazon, but why not support small(er) independent retailer?
In Minnesota here, Northern Brewer and Midwest Supplies have been the big retailers dominating the Midwest both online and with actual stores. But, Northern Brewer purchased Midwest back around 2013. There was little fanfare about this. More news hit when the venture capital arm of AB InBev, yes Budwiser et all, ZX Ventures purchased Northern Brewer/ Midwest Supplies near the end of 2016. Now, if you visit Northern Brewer, you will see promotions for other AB InBev High End Breweries; Goose Island, Elysian, and Golden Road. Northern Brewer/Midwest Supplies definitely has a large selection and almost everything you could need or want. Personally, I (Nate) am going take my business to other retailers. I have some suggestions that were given to me:
With two locations, Hermantown and Grand Rapids, wine creations is the closest retail shop and locally owned.
Retail store focusing on wine and wine accessories with some making items. Local.
Located down in Barron, this homebrew store has been around since the early 1990’s is some form and is now located a bit off 53 on the way to Eau Claire.
Based out of Plymouth, MN, known for beer dispensing equipment but also has a good supply of beer and wine making equipment and ingredients.
Internet: (I have purchased from some of these but not all)
There are many choices out there and many more than are listed above. Find what you need, shop around, pay attention to shipping and support homebrewing wherever you make your purchase from. Cheers!
