Because of its viscosity and\nsubsequent hardening, it forms a <strong>physical barrier<\/strong> that helps\nreduce water loss and direct exposure of damaged tissue to the environment.\nAt the same time, it contains various terpenes and other resin compounds that\ntake part in the tree&#8217;s defence against insects and microorganisms.\n<\/p>\n\n<p>\nThe response can continue after the initial injury.

If the resin cannot be separated without\ninterfering with firmly attached tissue, or if a fresh or moist surface appears,\ncollection at that spot is stopped. The aim is therefore not to \u201cclean the\nwound down to the wood\u201d, but only to remove resin that can be separated without\nfurther intervention in the tree.\n<\/p>\n\n<p>\nThis is also a key difference from active resin tapping, where an injury is\ncreated or repeatedly renewed specifically to stimulate further resin flow.\n<\/p>\n\n<\/div>\n\n\n\n\n\n\n\n\n<h2 id=\"sveza-in-starejsa-smola-v-cem-je-razlika\" class=\"wp-block-heading\">Fresh and older resin \u2013 what is the difference?<\/h2>\n\n\n\n\n\n\n<div class=\"translation-block\">\n\n<p>\nFreshly exuded spruce resin is generally softer, stickier and more strongly\naromatic. It contains a higher proportion of volatile compounds, which have\nan important influence on its scent and physical properties.\n<\/p>\n\n<p>\nOver time, some of these volatile compounds are lost, while the resin hardens\nand undergoes chemical changes. Older resin is therefore often harder and less\nstrongly aromatic, and its appearance may change from pale or yellowish tones\nto darker or greyish surfaces.\n<\/p>\n\n<p>\nAgeing, however, is not simply a process of \u201cdrying out\u201d. Additional resin may\nbe exuded at the same damaged site over time, and resinous material with a\ndifferent composition may also develop as the injury closes. Older resin can\ntherefore be a <strong>heterogeneous mixture of different resin phases<\/strong>,\nrather than merely fresh resin from which volatile substances have evaporated.\n<\/p>\n\n<p>\nCurrent research does not justify a simple conclusion that older resin is\nalways better or worse than fresh resin.

Even at the same damaged site, resin\nfrom different periods and of different origins may occur together.\n<\/p>\n\n<p>\nOver time, resin loses some of its volatile compounds, hardens and undergoes\nchemical changes. The tree may also exude additional resin at the same site,\nwhile resinous material with a different composition may form as the injury\ncloses. A single deposit can therefore contain softer, harder, lighter or\ndarker portions.\n<\/p>\n\n<p>\nNatural impurities also influence its appearance. Older deposits may contain\npieces of bark and other environmental material, so collected resin can also\nvary in cleanliness, texture and aroma.

We mainly collect resin that has already been\n        exuded by the tree and has partly or strongly hardened at the site of\n        an older injury. The condition of the resin and the suitability of the\n        site are therefore more important than a particular date.\n      <\/p>\n    <\/details>\n\n    <details>\n      <summary>Is spruce resin collected only in summer?<\/summary>\n      <p>\n        Not necessarily. Because we collect resin that has already been exuded,\n        there is no need to catch the moment when fresh resin is flowing from\n        the tree. Hardened resin can remain at a damaged site for several\n        years. When collection is actually possible also depends on conditions\n        in the forest and the arrangements for the particular area.\n      <\/p>\n    <\/details>\n\n    <details>\n      <summary>Does a spruce tree have to be cut to obtain resin?<\/summary>\n      <p>\n        Not with the collection method used by Smrekovit. We look for resin\n        that the tree has already exuded following an earlier injury.

Fresh and\n        older resin differ in their physical properties and chemical\n        composition, but age alone does not show that a resin is better, worse\n        or \u201cstronger\u201d.\n      <\/p>\n    <\/details>\n\n    <details>\n      <summary>Why does spruce resin vary in colour and hardness?<\/summary>\n      <p>\n        Its appearance is influenced by the age of the resin, loss of volatile\n        compounds, changes during exposure to the environment, later resin\n        exudation, and pieces of bark or other natural impurities.

Slovenian forest legislation\n        regulates resin collection as part of forest management. At Smrekovit,\n        we therefore arrange collection in cooperation with forest owners or\n        managers and the relevant authorities.\n      <\/p>\n    <\/details>\n\n  <\/div>\n\n<\/div>\n\n\n\n\n\n\n\n\n\n\n\n<div class=\"translation-block article-footer-meta\">\n\n  <div class=\"article-footer-meta__info\">\n\n    <div class=\"article-footer-meta__item\">\n      <span class=\"article-footer-meta__label\">Author<\/span>\n      <span class=\"article-footer-meta__value\">Matic Konc, Smrekovit<\/span>\n    <\/div>\n\n    <div class=\"article-footer-meta__item\">\n      <span class=\"article-footer-meta__label\">Last content update<\/span>\n      <time class=\"article-footer-meta__value\" datetime=\"2026-09-17\">17 September 2026<\/time>\n    <\/div>\n\n  <\/div>\n\n  <div class=\"article-footer-meta__sources\">\n\n    <h3>Scientific and legal sources<\/h3>\n\n    <ul>\n\n      <li>\n        <strong>\n          <a href=\"https:\/\/bsapubs.onlinelibrary.wiley.com\/doi\/10.2307\/2656626\" target=\"_blank\" rel=\"noopener\">\n            Wound-induced traumatic resin duct development in stems of Norway spruce (Pinaceae): anatomy and cytochemical traits\n          <\/a>\n        <\/strong>\n        <span>\n          Nagy N.
