Sierra Nevada, New Belgium and Lagunitas have all recently realized that to meet the demand of their products, they have to grow. Not simply grow the size of their brewhouse, but grow the size of their companies. This happens in two ways, through contract brewing or through building new breweries. Contract brewing is cheaper, and has historically been the most popular option with craft brewers up to this point. Building new breweries is expensive, but it increases the size of the business while still ensuring full control of the end product. Opening a new brewery is clearly the ideal scenario, but its prohibitive cost makes it difficult. The Boston Brewing Company, the largest American craft brewery, has done both with a long history of contract brewing and a more recently emphasis on opening new breweries as seen in Cincinnati.
Sierra Nevada

Does this affect Indiana? Probably not. There's a chance there will be a perceivable difference in the quality of the beer, but it's unlikely. It's possible they might pass the transportation savings on to us, but that's also unlikely.
New Belgium

Does this affect Indiana? Probably not. Much like Sierra Nevada, there's a chance that the quality of the beer might change, but it's doubtful. The bigger impact would be New Belgium's ability to distribute into more states east of the Mississippi River. Currently 17 of the 22 states New Belgium does not distribute to are east of the Mississippi River. Of the 5 remaining, 2 are Hawaii and Alaska.
Lagunitas

Does this affect Indiana? Most likely yes. It's hard to imagine a brewery producing 1.2 million barrels of beer annually with a brewery in Illinois wouldn't distribute to Indiana. Lagunitas is typically priced at the same entry point as Sierra Nevada is grocery and liquor stores, so you'll have one more low cost craft option.
What happens next?
That's a good question, and one up for speculation. With these 3 expansions, 3 more craft breweries will be producing well in excess of 1 million barrels per year. It seems like a new classification of brewery is in order. A brewery producing that much beer can't claim to uphold the same beliefs and practices as smaller, local breweries, but that also doesn't mean that they should be automatically cast into the same pile as breweries that put profits above consumers. Sam Adams faced the same issue a few years back when they grew outside of the definition of a "craft brewery." Their response was simply to continue brewing good beer and place a focus on their philanthropic efforts towards the craft beer community. As a result, hardly anyone noticed that they outgrew the classification.
Perhaps more importantly, what happens to the craft beer community in Asheville. In a community with 10 breweries (give or take), what happens when not one but two giants come to town. Will the community help each other and develop into one of the country's top beer destinations? Or will the new breweries cannibalize the existing breweries' profits?
