"Mainstream" ones like Black Rifle Coffee (which is trying to lose its political image and focus on being coffee for our military, now that it is big wants to be able to keep growing by "selling across the aisle")
But also a whole range of farther-right ones -- Liberty Coffee is one, Stocking Mill Coffee made a bit of a name for itself by commenting over the Kyle Rittenhouse controversy, Thrasher Coffee is another, and then there are a bunch more I can't remember the name of that make a "1776" or gun-themed roasts.
I've tried some of them -- like I said, they have dark roasts. Some are kinda trash and are clearly just trying to trade on the backlash against liberal coffee, others have pretty tasty dark roasts.
I just find it fascinating how dark-roast-focused the right-wing coffee scene is and how ultra-light-roast the left-wing coffee scene is these days.
I personally find "food partisanship" in America generally to be a fascinating topic, so I tend to go out of my way to experience some of the "controversy"
Coffee shops definitely have a vaguely liberal vibe to them.
Otherwise, though -- it is kinda funny that there's apparently a left-leaning association for coffee that they feel the need to push back on. Like coffee is kind of a ubiquitous thing that people consume to help them concentrate at their bland corporate jobs.
And the story behind sourcing it is... something that left leaning people are often not super psyched about. I guess that leads to the whole fair trade coffee thing, which... maybe that could be though of as left-leaning?
But whatever, the giant union-busting corporation Starbucks is sometimes assumes to be left-leaning, so what can you do, right?
The smaller "third wave coffee" shops generally have a liberal bent to them -- largely because the movement was born in Portland and Seattle. You are much more likely to see an "ACAB" sticker, a rainbow flag, or other left-virtue device on display than anything on the other side of the spectrum.
Starbucks may be anti-union, but they have frequently taken public stances of a liberal variety (particularly around visible issues like LGBT activism, and occasionally on guns) which has left those who felt alienated as a ready market for coffee without the moralizing (or coffee with their sort of moralizing)
I often try to find a mainstream trend in the other direction to compare it to, but there are so few mainstream consumer categories dominated by the right, mostly due to demographics.
Strangely quite a few seem to be drop shipped coffee. Which I didn't know was a thing, but seems to be a real enough business. I'm sure there are plenty of other brands doing it too.
Drop shipping, white label coffee is an enormous business these days - a considerable number of "influencers" have started launching their own "coffee brands".
Usually they are pretty cagey about the fact its white labelled.
So, they're just fleecing right-wingers by marketing them anything that's opposite to "the liberals"? I can't imagine making my coffee, beverage, or food preferences based on political affiliation.
Some of the products I've seen shilled almost exclusively to that market are hilarious.
One of my favourites is a certain "gold subscription" service, where you sign up for X$/month, and every time you have paid enough in to cover the cost of an amount of literal gold, they send you the gold.
I did some calculations at the time based on my own purchasing of gold in the past and worked out that people buying via that service are getting absolutely rinsed.
The ad/sponcon copy tends to blather about inflation, etc, etc.
In case you actually wanted to know, there seem to be two key incidents that led to Black Rifle losing their reputation as the place to get right-wing coffee.
The major one was an incident involving Kyle Rittenhouse. Shortly after his release from prison, he was photographed smiling and wearing some Black Rifle swag. This happened at a fairly sensitive time for Black Rifle, which was in the middle of opening its first physical coffee shop (in San Antonio, I think). The owner/founder posted on social media some negative commentary about Rittenhouse and indicating that the swag was not given by the company and did not represent the company's support of either Rittenhouse or his actions. As you might expect, the social media "conversation" on the subject got very hot very fast. One of the smaller right-wing coffee shops stepped into the fray and became very vocal supporters of Rittenhouse and his defense, making a bit of a name for themselves (and possibly a lot of money).
The lesser event actually occurred first, and was also some commentary that the owner/founder of Black Rifle Coffee made. I wasn't following the Food Partisanship beat at that time, so I don't know exactly what was said, but he posted to social media some commentary about gun rights that was less guns-for-all than you'd expect from a company with their imagery (and product names), and that talked about the pro-Trump part of the Republican party as not being the good guys, whether armed or not.
There's been some debate about the degree to which these incidents were about a company trying to continue to grow (and thus needing to gain mainstream "legitimacy") or whether the founder was actually never a right-wing ally -- but either way, these events were seen as a betrayal by a portion of the right-wing coffee community.
