I live not too far away from primitive beer and I went to their grand opening. I love that there is a big enough beer scene in Colorado to be able to support experiments like this: we have some a few all craft lager breweries popping up and now we have a traditional lambic brewery — it's a great time to be a craft beer lover in Colorado.
In addition to serving beer in boxes, at the brewery they serve it using beer engines and ferment in a ton of barrels that are stacked everywhere. Their coolship is in the corner of the taproom so I got to lean in and look at it up close which is super awesome.
The beer was not the spectacular lambic that you get in Belgium, but it was interesting. They're still very new and they are passionate enough that I imagine it will only improve over time.
