It is common practice to allow drinking coffee pretty much anywhere. It is also widely accepted to drink unflavored beers. Would that logic allow one to drink beer that is commercially brewed and/or flavored with coffee?

TRiG thanks for the fix – brewjew Jul 3 '13 at 0:21
brewjew, welcome to Mi Yodeya, and thanks very much for bringing your question here! Awesome username. Perhaps you'd be interested in taking a look at our 15 other questions about alcohol or, more broadly, at our 278 other questions about kashrut. – Isaac Moses Jul 3 '13 at 1:07
Just curious: why would it be non-kosher? Assuming that the coffee is kosher (I know of no reason, personally, why it wouldn't be), and assuming that it's not Pesach, under what circumstances would the combination of the two result in something forbidden for consumption? – Shimon bM Jul 3 '13 at 1:12
@ShimonbM, I think the concern is whether they are acceptable without certification. – Yirmeyahu Jul 3 '13 at 1:57
Just a point in fact, usually coffee-flavored beer is not flavored with brewed coffee, but with coffee beans. – Charles Koppelman Aug 2 '13 at 18:16

Second ShimonbM's comment. Practically, as soon as we hear "flavored beer" we get worried what might be in there. Without any further information I wouldn't buy a non-hechshered "coffee-flavored beer" at the store for that reason. However if you're certain the only ingredients are wheat, barley, coffee beans, hops, yeast, and water, and the equipment isn't used for anything else (are you brewing your own?), I can't see the issue.

(With regards to both coffee and beer, the question is raised [Kitzur Shulchan Aruch 38:12] why they're not prohibited under the ban on gourmet-food-cooked-by-non-Jews. The answer given to both is that the main ingredient is water, which doesn't need cooking! I thus can't see how coffee-with-beer would be any different.)

Wouldn't the non-application of the aforementioned restriction depend on the basis for its non-application in those other cases? I mean, if the basis is that they are too basic and consumed by average Joes, might it not be conceivable that a niche beverage prepared in a trendy bar/restaurant qualifies as gourmet? – Seth J Jul 3 '13 at 1:53
Your argument would apply equally to any flavored beer (or other processed product that doesn't rise to the Halachic "gourmet" status?) that has ingredients that are all known to you and inherently innocuous. So coffee beans, in this instance, are no different than, say, apples. However, wouldn't we still be worried about ingredients you don't know about and about equipment? – Isaac Moses Jul 3 '13 at 3:04
@SethJ sorry I threw you the wrong direction here. The reason (see Kitzur Shulchan Aruch 38:12) we permit coffee and beer is that the main ingredient is water; thus permitted, gourmet or not. I was just mentioning by the way that the only prohibition is on gourmet items. – Shalom Jul 3 '13 at 9:00

There are very few commercial beers which don't use GMO's (Google GMO beer). There is no way GMO's can be considered Kosher. Mixing coffee and beer should be fine as long as they are Kosher and not drinking until drunken.

Lev 19:19 "'You shall keep My statutes. You shall not let your livestock breed with another kind. You shall not sow your field with mixed seed. Nor shall a garment of mixed linen and wool come upon you."

thank you and welcome to J.SE. It's a subject of another question, but yes Judaism prohibits cross-grafting two different plant species, however the product of such an action remains kosher. Therefore genetically modified organisms are certainly kosher after-the-fact. – Shalom Aug 4 '13 at 15:05
Thank you for tolerating me. I would have to disagree with GMO's being the same as grafting since you are mixing animal dna with vegetable dna. And the horrible cancers proven by GMO's can leave no doubt that it is not Kosher.Thou shalt not eat any abominable thing. Deut 14:3 – WillieNAz Aug 4 '13 at 17:40
"You shall not sow your field with mixed (kil'ayim) seed." GMO's are indeed mixed beyond cross breeding. Cross pollination can give the same results as grafting, but nature can not produce what GMO's produce. If something is certified Kosher in ignorance, is it still Kosher? Should I eat a package of bacon with a "K" on it placed there by mistake? I am called to have my own discernment. I think there needs to be a lot of pressure put on certifying GMO's as Kosher before the damage is done. Sterility and autoimmune diseases will destroy His children. – WillieNAz Aug 4 '13 at 17:54
