Sparkle would make great wine. It gets very high in sugar and has great strawberry, not straw, flavor. Yields are great and it is one of the older more dependable vaieties that will grow just about everywhere. They are junebearing- not everbearing so you can concentrate the crop good to get enough for a batch in a hurry.
Our local strawberries are the pajaro variety..many are huge and watery, for eating mainly.. I tend to purchase the fruit 'seconds' for jam and wine.. these are the small strawberries, better flavour concentration and you get them really cheap. They sell the huge ones with stems to the local restaurants.
80% of NZ crops are this variety.
Pajaro; Type: Short day, General description: UC variety. Consistently very large. Bright red skin, light red flesh. Exceptionally firm. Excellent flavour when picked fully ripe but can be insipid when picked under-ripe. Early crops if not deflowered. Average yields, but exceptional quality results in high export grade out.
( I'm currently trying to source alpine strawberries, which crop year round)
