Seasonal Resin Blends: Winter, Spring, Summer, Autumn

Seasonal resin blends are incense mixtures assembled to match the character of a season, pairing warm, heavy resins such as frankincense, myrrh and labdanum for autumn and winter with lighter, greener or citrus-forward materials such as galbanum, elemi and pine resin for spring and summer. The practice is not folklore: it follows how resin chemistry reads to the nose in cold, damp air versus warm, dry air, and how a room’s ventilation and humidity change perceived intensity. Winter blends lean on ambery, balsamic base notes; spring blends favor green, terpene-rich top notes; summer blends stay light to avoid heaviness in heat; autumn blends bridge the two with spice-toned resins like dragon’s blood and tolu balsam. There is no single fixed formula — blends vary by tradition — but the underlying logic of matching resin weight to season recurs across cultures and centuries.

What defines a winter resin blend?

Winter incense favors resins that are slow to volatilize and read as dense even in cold air. Frankincense, tapped from Boswellia sacra and Boswellia carterii, contributes a bright, slightly citric top note from α-pinene and limonene sitting over a drier, incensole-rich base. Myrrh, from Commiphora myrrha, adds a darker, bitter-medicinal edge carried largely by furanoeudesma-1,3-diene and curzerene.

Labdanum, harvested from the leaves of Cistus ladanifer, brings an ambery, leathery sweetness from sclareol and related labdane diterpenes, and is one of the closest natural approximations to what perfumery calls “amber.” Siam benzoin, from Styrax tonkinensis, rounds these out with vanillin and cinnamic acid derivatives, giving a soft, balsamic sweetness that keeps a winter blend from feeling austere.

These four materials, in roughly equal parts, form the backbone of many church and monastic incense recipes, which historically were burned in cold stone interiors where a light, transient scent would have been lost.

Spring blends: green and resinous

As temperatures rise, incense makers typically shift proportion away from heavy ambery bases toward green, terpene-forward materials. Galbanum, the oleoresin of Ferula gummosa, is the most assertively green resin in general use, dominated by pinenes and a sharp, sappy bitterness that some burners find better diluted with a sweeter resin.

Pine resin and rosin, discussed on Benjuí’s pine resin, rosin and turpentine page, offer a gentler version of the same green-forest character, largely from α-pinene and β-pinene with lower intensity than galbanum. Elemi, from Canarium luzonicum, adds a lemony, slightly peppery lift from limonene and elemicin, and is often used as a bridge between green top notes and a sweeter resin base.

A workable spring proportion is small — galbanum used at perhaps a tenth of the blend by weight, since its intensity outpaces its bulk, with elemi and a modest amount of frankincense filling out the rest.

Summer blends: staying light in heat

Warm air accelerates volatilization, so resins that feel balanced in a cool room can turn heavy or cloying in summer. Blends built for warmer months generally reduce or drop labdanum and myrrh, and lean instead on elemi, a small proportion of frankincense, and citrus-leaning terpenes such as limonene and α-phellandrene.

Burning method matters as much as material choice in summer. Lower, steadier heat — as described in Benjuí’s guide to how to burn resin incense — prevents scorching, which produces a burnt, resinous smell that reads as unpleasant rather than warm when a room is already hot. A thinner charcoal ember or a lower electric heater setting keeps volatiles releasing gradually rather than in a single sharp burst.

What does an autumn resin blend smell like?

Autumn blends typically smell warm and faintly spiced rather than purely sweet or purely green — a transitional profile between spring’s sharpness and winter’s density. Dragon’s blood resin, from Daemonorops draco, is a common anchor: its red pigment dracorhodin does not contribute much odor itself, but the resin’s terpene and resin-acid content gives a dry, faintly fruity, woody-spiced character.

Paired with tolu balsam, whose cinnamic and benzoic acid esters add a warm sweetness, and a small portion of benzoin for vanillin softness, dragon’s blood produces a blend that reads as spiced rather than floral or resinous-green. This is close to the profile many people associate with “autumn” candles and incense, though natural dragon’s blood is considerably drier and less sweet than synthetic fragrance versions of the same idea.

Building a seasonal blend: a proportions guide

The table below gives a starting point rather than a fixed recipe; individual resin batches vary in strength by origin, harvest year and grade.

For a first attempt at any of these, Benjuí’s guide to DIY resin incense blends walks through grinding, mixing and burning small test batches before committing to a larger quantity.

How to burn and store seasonal blends

Resin blends are almost always burned on charcoal or a low-temperature electric heater rather than lit directly, since resins melt and vaporize rather than combust cleanly on their own. Charcoal gives a hotter, more immediate release that suits denser winter blends; a controlled electric heater suits the lighter spring and summer mixtures, where a gentler, sustained heat draws out top notes without scorching them.

Storage affects how a seasonal blend performs the following year. Resins absorb moisture and lose volatile terpenes over time, particularly the greener compounds in galbanum and elemi, which fade faster than the heavier diterpene acids in labdanum or frankincense. Keeping blends in sealed glass jars, away from light and heat, preserves the balance intended when the mix was made — a mismatch here is often why a carefully built spring blend smells flat or unbalanced by the time autumn arrives.

A note on tradition versus formula

Seasonal blending is a practical habit more than a codified system. Historical incense recipes, from church thuribles to Japanese nerikō, were shaped by what was locally available and by liturgical or ceremonial calendars rather than by a theory of resin volatility. The seasonal logic described here — heavier resins in cold months, lighter ones in warm — is a useful starting framework, but the resins themselves, from Boswellia and Commiphora species to Styrax and Cistus, carry enough individual character that most incense makers eventually settle on proportions by trial rather than by rule.
