Weyebacher

Weyebacher Brewing has been a brewery I've been interested in but I know they do a bunch of flavors. I decided to reach out. They have brewed an oyster stout in the past and they said they "don't often" brew it, but that doesn't mean they wont do it again. The bigger issue is that they do contract brewing for several other breweries in their area. As such, they are not recommended by the Star K.

Market Garden Brewing

Market Garden Brewing is base here in Cleveland, OH. I've heard some good things about their wheat beer. They don't use any animal products (except for honey and that's only at their taphouse) in any of their beers. They don't share facilities and their brewpub is separate from production. Their unflavored beers would be acceptable according to the Star K.

Brew Dog Brewing

Brew Dog seems to be a new brewery (to me at least). Their HQ is in Columbus. There is a Brew Dog in Cleveland on Lee Road. I've been curious to stop by there. First off, the rep who responded to the email was extremely friendly. Even thanked me for the email and getting so in depth. They are a self proclaimed "experimental and innovative brewery," so they utilize a number of different ingredients in some of their beers, however, the majority only use the 4 main ingredients. While they have made various experimental beers, they haven't, as of yet, made a true oyster stout. They have aged beers in wine casks. They do not share facilities with other breweries, but they do make collaboration beers with other companies. According to Star K guidelines, the unflavored beer should be alright as long as they don't make an oyster stout.

Mad Tree

Mad Tree is brewed in Cincinnati, OH. Based on what I've seen in stores, they seem to do a number of flavored beers and some ciders. I decided to reach out anyways just due to prevalence in the stores. They brew with a number of flavorings from fruit purees to lactose to cacao nibs to vanilla beans. They have made an oyster beer in the past, but it was a one off according to a company rep. They do not share facilities with other breweries, so that makes this a lot easier. While they do age in wine casks and spirit barrels, those should be marked on the cans. According to the Star K guidelines, the unflavored beers from Mad Tree are acceptable.

3 Floyds

3 Floyds Brewing is based out of Munster, IN. They are a newer beer I've been seeing in the store lately. I've been eyeing their Scottish Ale for a while now. They do not share their facilities and most of their beers are vegan (those brewed with lactose or honey are labeled as such). Tey do age in wine casks, so that may be an issue depending on how you hold. According to the Star K guidelines, the unflavored beers should be alright.

Hi-Wire Brewing

I recently started seeing Hi-Wire Brewing beers at the grocery store. I reached out last week to see what their situation is. They do not brew oyster ales. They do use lactose for some beers and it's listed on the product. Their sour and wile ale beers are aged in various barrels, also on the labels. They do not share their facilities or outsource their beer production. According to Star K, Hi-Wire is acceptable.

Stone Brewing

Stone Brewing is a company out of CA. They have been around for a long time and have a very solid selection. I haven't had their "Arrogant Bastard" in a while (before all this experimental beer stuff took place), but I remember it being very good. Especially for the price. They occasionally brew with spices, wheat, coffee, lactose, and fruits in which case, it will be noted on the label. They don't do any experimental beers and do not share facilities with other companies. According to the Star K guidelines, their unflavored is acceptable.

Dominion Brewing

Dominion Brewing is out of Dover, Delaware. I have seem there beers in multiple states and they have a few that I really wanted to try, including an oak barrel stout. After reaching out to them, everything sounded good until they mentioned they planned on making an oyster beer in 2019. Due to this, they cannot be recommended by the Star K.

Hops and Grains

Hops and Grains is a brewery in Houston, TX. I reached out to them to try to get some more information. Unfortunately, they didn't give me much to work with. They answered maybe half of my questions and even then didn't give me much information. Due to that, It doesn't look promising.

Deschutes Brewery

Deschutes Brewery is known for it's Black Butte Porter and Mirror Pond Pale ale.

The majority of their beers are made using the traditional ingredients, but they occasionally use cacao nibs, fruit purees, etc. The extra ingredients are always posted on the label, so that makes it very easy to identify.
They don't brew any beers with animals or insects, but they do brew milk stouts and a milkshake IPAs from time to time in their pub. Their pub is completely separate from their brewing facility.
They do share facilities, but only for collaboration brews. They don't brew or package for other breweries.
They do make a few beers that are aged in wine and one that actually uses grapes (Pinot Suave).

Their unflavored beers that are not aged in wine casks or brewed with grapes would be acceptable according to the Star K.

Revolution Brewing

I've seen Revolution Brewing in the store for a while now and decided to reach out to them.

While quick in their response, they were not very forthcoming with information. They would not share much information with me regarding their process. Since I could not get much information, I was unable to get an answer from the Star K if it would be acceptable.

Their status right now I would say is not recommended until they provide more information.

New Holland Brewing

New Holland Brewing makes some delicious beers. I'm a huge fan of their Dragon's Milk and Porter.

They do make some brews with lactose or flavoring. Any flavoring is on the label, so it's easy to identify.
They do make some sour beers in old french wine casks, so that can be an issue for those beers.
They do not make any experimental beers or use wine yeast. They used to make a beer with champagne yeast, but that's fine.
They do share their lab with smaller breweries, but nothing from the lab is shared with their production line.

In conclusion, their unflavored beers are acceptable by Star K standards.

Troeg's Brewery

Troeg's Brewery has some beers I've really wanted to try. The Troegenator, HopBack, and Dead Reckoning to name a few. This one took a while to get a hold of, but eventually I was able to get them to answer my questions.

They do not use any animal byproducts in their beer at all, but they do use fruit and coffee beans. They don't use any wine in their beers at the moment nor do they share facilities with anyone else.

Based on the info they gave me, their unflavored beer is acceptable according to the Star K .
