frequently asked questions

Does Brewsy work with juice with preservatives, or pasteurized juice?

Yes, it does! The Brewsy formula can actually work with nearly all store-bought juice (even Arnold Palmer, if you’re feeling adventurous).

In U.S grocery stores, most juice is preserved with ascorbic acid, which works completely fine with our formula.

If you’re shopping in the international aisle, keep an eye out for juices with potassium sorbate, though. It’s not often found in U.S-made juices, but it’s the one preservative that won’t work with our formula.

The Brewsy Bag isn't just yeast, right?

No, the Brewsy bag isn’t just yeast at all — it’s actually a blend of five ingredients. Over hundreds of tests, the Brewsy bag has been carefully formulated to make sure YOU make the best wine possible!

Transparency is important to us — as well as knowing exactly what’s going in our bodies. Because of that, we want to share exactly what we put into each and every Brewsy bag:

1. An industry-exclusive wine yeast

2. A carefully-blended mixture of micronutrients

3. Potassium bicarbonate (to cut down on acidity)

4. Bentonite (a volcanic clay that adds clarity to your wine)

5. Malolactic culture (to turn harsher flavors into softer, smoother ones)

is it gluten free?


brewsy is 100% gluten-free and made in a facility that does not process gluten-containing ingredients.

is it keto? low-carb? low-sugar?

yes! brewsy is 100% keto-friendly and every single recipe has a 'low sugar' or keto setting! in fact, you can CHANGE any full-sugar juice into a low-sugar wine with brewsy!

100% of our recipes can be made keto-style with as little as 1g of sugar per serving. simply pick a recipe, then use our sweetness calculator on our starter recipe page and choose 'DRY | KETO'. after your wine/cider is done, you can add monkfruit, stevia, etc to taste!

when does it expire?

brewsy bags: the brewsy bags (packets) will last 1.5 years in storage.

wine or cider: your wine or cider will last 3-5 years in your refrigerator!

how sweet will it be?

great news: it's 100% up to you!

we build a really cool sweetness calculator that works with ANY of our recipes and it lets you pick whether you want your wine dry / keto, semi-dry, semi-sweet, sweet, extra sweet, or dessert wine! you can check it out in action in our starter recipe at

why isn't most wine vegan?

Almost all wines that you'll find in the store go through an unnecessary clarifying step where gelatin (from pigs) or shellfish products are used to make the wine more clear. Fortunately, you can instead clarify the wine you make at home with a mechanical step called racking. The Brewsy Bag is completely vegan, made without any animal products.

what if I don't like it?

Just text us and we'll give you a 100% refund. You'll get our cell when you open up your package.

how it works
step 1
grab any sweet drink
grab any juice or sweet drink – or make your own.
step 2
make it a little sweeter
wine grapes are twice as sweet as juice, so we need to add some sugar.
step 3
add a brewsy bag
simply tear open & pour in the brewsy bag. then shake it up!
step 4
add our special airlock on top
our airlocks seal off our juice but still lets bubbles escape. they fit in any container.
step 5
yeast eat sugar
your yeast wake up, swim around, and eat some sugar for five days! in exchange, they make alcohol & bubbles. the yeast go dormant when your wine is 12% ABV.
step 6
separate the yeast
leave the juice in the fridge for 2 more days so the yeast fall out of the juice and settle on the bottom of the container.
what's in the box?
everything you need to make 12 bottles of wine and more!
three magical brewsy bags!
three airlocks
an amazing winemaking book!
stickers to label your juice!

two glass gallon jugs!
2.5 gallons of fresh juiced wine grapes!
an awesome funnel!

My favorite new hobby!

I am so happy I found Brewsy! I wasn’t sure it would be as good as it sounded but It’s even better! It’s easy and fun and delicious! The customer service and Brewsy community has been amazing!

Kim Kraus (Satellite Beach, US)
So much fun!

I have been wanting to try brewsy for a while now. Got it for my friend as a birthday gift in the summer but was secretly super jealous :). Then I mentioned I wanted it to my husband in December and he told me to buy it without a second thought. And now here we are 5 batches in - black cherry plum, mead, apple cider, peach mango v8, and white cranberry. Each person that tries them has a different favorite one! Love the process and it’s so different with each batch I make. The variety is limitless. Thanks Brewsy!

Thumbs up!

I've always loved making wine, or beer, etc. Brewsy helps make it super easy and convenient. And obviously extremely good customer service, etc. Definitely try it if you haven't :)

So easy even I can do it!!!

I love wine- not just one specific kind- I love trying all kinds of wine! I also have a brain injury and following instructions can be difficult- lucky for me, and you, Brewsy makes the task of brewing our own wine very easy! I’ve made several batches, bought some extra supplies and felt an overwhelming feeling of pride on Christmas when my family enjoyed 4 bottles of wine with our festivities! There is a little work involved, most of it being patience, but that’s easy considering the amazing wine we get to enjoy! I’ve bought kits for friends and family and can say I’m going to be a lifetime Brewsy user! A lot of pride comes in those little Brewsy bags!

Christine C. (Sanbornton, US)
Brewsy is awesome!

Brewsy is easy, fun, makes great wine, and the Brewsy team is awesome! Thank you!

Joyce Barron (Tacoma, US)

Started researching how to make healthy, clean, organic wine and found Brewsy. I have digestive issues and can't drink store wine because of the sulfates and I try to consume only organic products. I'm on gallon #7 and am in LOVE with the process, the ingredients, and the end product ❤️❤️❤️ Thank you Brewsy!

LeeAnn Smith (Huntsville, US)
Good to the last drop…..

Having the last glass of my Christmas cranberry pomegranate!! 🎄

Debra RayWilson (Mountain City, US)
A hobby to enjoy, drink and celebrate with family and friends.

It's so easy to do. Buy the starter package. Buy any juice that you like to drink.
Add recommended amount of sugar per brewsy website.
Put it together per instructions.
Each day give it a little swirl, after 5-7 days, cold crash in refrigerator like the instructions
After 7 days, take a little sip, then a taste, then a glass, call some friends, have them bring the food because you've supplied the wine....PARTY....WOO HOO PARTY!!

Rick Smith (Burlington, US)
I am loving my new hobby!

I just finished bottling 14 bottles from 3 gallons of brewsy wine. I am loving my new hobby. To me, it is much better tasting wine than I get from the store or from wine sellers. There are no harsh chemicals so I'm getting the true taste of my wine. I have a feeling I will be making wine for a good while now.

Allison Walker (Pawtucket, US)
Never knew you could even make wine from home,,thanks Brewsy 🥂

Been making wine just a year now I enjoy and look forward to trying each new batch and my co-workers family and friends don't mind the free samples I'll never run out of ideas!!
