These processes almost always call for added sugar that counterbalances the tartness of under-ripe fruit.With this DevLog we want to share with you some of the development progress that’s happening in Red Frost. Use the fruit in baked goods, sauce, or canned goods.If you have to pick early, try storing the fruit for a while to see if they become sweeter before use. Apples are a “climacteric” fruit, meaning that they continue to ripen somewhat after picking.To make sure the apples can survive long-term storage, the orchards harvest them 1-2 weeks before peak ripeness. Many apples sold to grocery stores are stored for weeks or months before hitting the shelves. Store your fruit for a few weeks before using it.If you do have to harvest under-ripe fruit, your options are: If you see your fruit getting eaten and cannot protect it, you may have to harvest early to save what is left. For example, ripening fruit are attractive to creatures like raccoons, birds, and brown marmorated stink bugs. There may be scenarios where you have to harvest your apples before they are ripe. Ripe apples have a brix of at least 12-13. We use a refractometer to measure the sugar content (brix) of the juice after blending and straining it from the apple. Home gardeners could use this method, except that finding the correct iodine solution would be challenging and expensive. Once about 20% or less of the surface stains blue, orchards harvest the fruit. As the apple ripens and converts starch to sugar, the spray will create less blue color. The starch in the solution stains the flesh blue - the bluer the flesh turns, the more starch the apple contains. They cut open an apple and spray the surface with an iodine solution. Orchards can closely monitor their apples’ transition from starch to sugar by using a starch-iodine test. Not all orchards use these tests, as some still rely on taste and appearance. These include the “starch iodine test,” measuring juice brix (sugar content). But they also have two other tools to more precisely measure ripeness. Your local U-pick orchard measures ripeness the same ways described above. Other varieties like State Fair and Zestar! lose crispness during storage. Most UMN varieties, like Honeycrisp, maintain that firm, crisp texture through harvest and storage. If an apple is hard to bite into, it is probably not ripe yet. Please note that many apples will turn color before converting all of their starch to sugar, so the flavor is still a more important indicator than color.Īpples often change texture as they ripen, going from hard to either crisp or mealy. A yellow background color is one indicator that the fruit may be ripe or nearly ripe. The red is the “over color” and the yellow is called the “background color.” If the background color is green instead of yellow, it is not ripe. In addition to flavor, look for apples with red and yellow skin. If you taste an apple like this, it is not a fault of the variety - the apple is meant to be left alone to ripen longer. If you bite into an unripe apple, the starch will create a feeling on your tongue that some may describe as dry, sticky, or astringent. As apples ripen, their starch converts to sugar. Throughout the summer, unripe apples contain a lot of starch. Apples in the center of the tree are more shaded and ripen more slowly than apples on the outside and top.Īpple growers can use fruit color, sugar content, loss of starchiness, and flavor to decide when to harvest.Ī ripe apple should be sweet, have a pleasant (non-starchy) mouthfeel, and be red with a yellow background color. Honeygold, Haralson, Frostbite, Regent, SnowSweet, Fireside/Connell Red, Keepsake, and Prairie SpyĪpple ripening varies greatly by variety and even within the canopy of a single tree. Typical ripening by variety Early season varieties (mid-August to early September)īeacon, Paula Red, Zestar!, State Fair, and Centennial crabapple (plus First Kiss and SweeTango - not available to home gardeners) Mid-season varieties (mid or late September)Ĭhestnut crabapple, Red Baron, Sweet Sixteen, Triumph (new), and Honeycrisp Late season varieties (late September to October) This includes Minnesota’s state apple, the beloved Honeycrisp, which we harvest from late September to early October. Most apple varieties available to home gardeners in Minnesota are harvested after mid-September and before Halloween. Instead of waiting until a frost, use a few simple, smart guidelines to decide when to harvest your apples. This is because each apple has a different ripening time, anywhere from mid-August to October. If we followed that rule, many of our apples would be rotten or on the ground by the time we picked them. Have you heard the old wise tale that you should wait until after a frost to harvest your apples? I am here to bust that myth. Minnesota apples are tempting us to harvest them.
