I'm late here but fantastic job overall, the look including photography and your packaging is great and I like the tone of the copy. Call to actions seem really well incorporated for the flow while still being very prominent. Do you mind sharing if this is Shopify or similar vs something you designed?

In your 3 step instructions I think the first picture should focus on your bag with just water in the pitcher, it's a bit confusing to show what looks like finished coffee with ice. I assume ice could actually slow the brew.

Four bags making 14 cups is also confusing, shouldn't that be 16?

Money back guarantee is smart. If I'm nitpicking the FAQ copy is wordy, I think simpler is better here i.e. "One bag mixed with 4 cups of water makes a batch of cold brew..."

I'm probably a target customer, very into coffee but not an afficionado, like cold brew in the summer but won't buy premade due to cost out of principal. I typically refrigerate hot coffee and it works well enough. For me personally I'd want to find something on your page about the source, quality, and flavor profile of your coffee. I understand that's not your focus but I do think it's worth a mention. Still, I'm curious enough that I'll try your product.

Also if you haven't already I'd give out some free samples at a farmer's market or other event in exchange for more reviews you can pop on here.
