I don't know how many of you read the comments section, you really should, but within a couple of hours of posting the picture of my sediment laden beer glass, Jeff from Tallgrass commented with an explanation.
Hop stems would be my guess from the looks of it. Oasis is unfiltered and whole-leaf dry hopped for two days in four big cheese cloth bags in the brite tank prior to canning/kegging. We leave about 1-2 barrels in the tank at the end to avoid this, but it looks like some got through. Unfiltered plus brite tank dryhopping equals nice beer but at a risk of this happening. What is the code on bottom edge of the can?I responded with the code and it turned out it was an expired can of Oasis. I then emailed with Barb who also commented. I have a fresh 4 pack of Oasis on the way and I'm completely satisfied with my experience.
Brewing beer is a complex process, sometimes something gets through that shouldn't, especially in an unfiltered beer. If you drink enough beer, you'll get a bad one, more so with a newer, smaller brewery. I know of a case this week where someone got a bad Boulevard Imperial Stout. It happens. But, how a brewery or restaurant responds says quite a bit about how they view quality (I still haven't forgotten the McCoy's waiter in this story). Tallgrass has passed that test.
My only recommendation would be for Tallgrass to make the best by date an actual date rather than a code so I know if it's expired or not.
If you get something wrong with your beer, don't hesitate to call or email the brewery, they'll probably try to make it right, just don't go all McKenzie brothers on them.
