This is what THP was referring to with "boiler plate" style...
And this is how the finals turned out:
Just an example of branding. I've seen companies who use different images for each flavor and different logos and such - each to their own. I prefer the consistent look.
Also, I agree with SL - but not entirely - about looking at other imagery to determine your tastes. Rather than hot sauce labels though I'd recommend looking at graphics for all kinds of product labels. Think about products that you like. When developing my logo my designer asked me what kinds of imagery I liked in products - what did I consider a "classic". I suggested a few things...she suggested a few things... I told her I wanted a symbol of luck - unfortunately the 4-leaf clover looked more like I'm selling "Irish sauce" and the rabbit's foot was a bit grim so we landed on a horseshoe. I also told her I wanted a dog, "something iconic like a black lab".
She mocked up a basic label in each of the 4-5 styles - we ended up going with a hybrid of a couple.
Just giving insight to the process I went through - it can be quick if you really know what you want, but I trust the designer's eye more than my own. you can have a very basic concept in mind and the designer can refine it for you, or you can have a detailed image in mind and instruct the designer accordingly as you go through the process. I feel like I have good taste but I'm not a great artist - so I let my designer do the "heavy lifting" and gave feedback for revisions based on what I and a select group of friends thought. Over time we added things like the hot pepper silhouettes at the bottom, added "hot sauce" to the horseshoe (partially for trademark/legal reasons), we modified the horseshoe to have more shadow effect, changed the LUCKY DOG to a gold fade effect, etc, etc, etc. In the end I think she created a really cool graphic that I absolutely love, and also something iconic that a lot of folks seem to like too.
Another suggestion is to have accuracy in labeling. I've read many product reviews that will downgrade your product if you have say, skulls and blood and boobs and death and explosions and terror on your label, but your sauce tastes like unicorn kisses and kitten purrs heat-wise. I opted to avoid that whole game and just do a label I love without any of that - mine's a food product not a crazy-hot sauce so I wanted my label imagery to be accessible. If you have something on your label that looks like a cover of Heavy Metal magazine you're really limiting your audience in my opinion because that imagery, no matter how cool or edgy you think it is, won't resonate with everyone and it might be a downright turn-off to some.
If you're selling 9,000,000 scoville sauce, by all means - scare people with your label, just like a hornet or a black widow or a kimono dragon engenders a healthy respect with their appearance. Just saying to plan accordingly.
Does your sauce have a name yet? There's a great place to start.
