Oh interesting! I've made strawberry wine a few times and the first time I made it, it came out a beautiful rose colour. I made a 3 gallon batch this year. It's currently just about finished in the primary (2 weeks), and it's a much darker, deeper red than last year, like the colour of cranberry juice. I used about 4.5 lbs of strawberries/gallon, so 13.5 lbs total.
I've had strawberry wine from a farmer's market and it was definitely orange. I thought at the time that it was due to the wine oxidizing a bit too much (it was a bit vinegary) but now I wonder if it comes down to the variety of strawberry used, and possibly how ripe it is. I get my strawberries from a u-pick farm and the variety they grow are red right down the core. Strawberries at the store almost always have a lot of white inside when you cut them down the middle. I guess those are a variety that ship well. The ones I picked would barely last one day on the counter. I'm wondering if strawberries with less red would have a harder time passing on their colour to the wine...
