I really like this logo!
I suggest you do more with background color. At this time it probably doesn't matter, but when you have a dozen batches in the racks, quickly identifying wines becomes difficult if the labels all look too much alike. I have a page that displays the labels I have a record of:
https://wine.bkfazekas.com/bottle-label-progression/
Skip down to the 2012s and scan through to 2018. In hindsight, the labels have different text but all look alike. Finding things in the racks when you have a dozen batches and anywhere from a few bottles to a few cases of each wine, this can be difficult. I've switched to using a background image, which I fade out using Paint.NET, so each label has common features (winery name, my Grape Warrior logo + tag line OR my son's sword logo), bottling date, ABV), but everything else varies. It makes finding things easier. Plus I like designing labels.
I also have enough capsule colors for 7 or 8 batches, so in a year each batch gets a different color. I buy in lots of 500 so that it will be quite a while before I run out of a color in the middle of a batch.
Food for thought ....
I thought I jumped into the deep end with winemaking.
After seeing that you have an entire site dedicated to your wines, a chronological record of the labels, all your wines, etc. It is clear I'm not even waste deep strolling around in the shallows.
Cool to see, thanks for sharing that.
I have in mind the same idea for the logo as your grape warrior. I too like playing around with the labels.. I can shrink it and put it in a corner, or under a description of the wine or occasion.. I was planning to cap these batches with heat shrink caps. mostly for the fun of it, but it makes sense to identify the wines as well.
Now that these batches are racked I'm already itching to start another couple.. It will be important to have some variation for sure.
