What cut grade of peppermint is standard for tea-bag manufacturing?

Cut-and-sifted (C/S) with a particle size range of approximately 1.4 mm to 5.6 mm is the standard grade for tea-bag and pyramid-bag production. This range ensures consistent bag-fill weight on automated lines and delivers a controlled infusion rate. TANDOR specifies the sieve range on the Certificate of Analysis for each batch and can adjust it to match a buyer's bagging equipment or product specification.

Is irradiated peppermint permitted in EU organic herbal teas?

No. Irradiation is incompatible with EU organic certification under Regulation 2018/848, which prohibits the use of ionising radiation on organic products. Even for conventional herbal teas, irradiated ingredients must be declared on the label under EU Directives 1999/2/EC and 1999/3/EC, and many retail buyers refuse irradiated herbs entirely. TANDOR clearly documents the sterilisation method — steam or otherwise — on every batch CoA so manufacturers can make an informed procurement decision.

What microbiological limits should tea-grade peppermint meet?

Tea-grade dried peppermint destined for infusion — where no further kill step occurs — should typically meet: Total Aerobic Count ≤ 10⁵ CFU/g (pre-sterilisation), Enterobacteriaceae ≤ 10² CFU/g, Salmonella absent in 25 g, E. coli absent in 1 g, and yeast & mould ≤ 10³ CFU/g. These align with EFSA guidance on dried herbs and industry standards such as BRCGS. Post-sterilisation limits depend on the customer specification, and TANDOR can source to tighter targets on request.

Can TANDOR supply EU-certified organic peppermint with full traceability documentation?

Yes. TANDOR supplies peppermint certified under EU Organic Regulation 2018/848, with organic certificates from an EU-accredited control body traceable to the production unit. Each shipment is accompanied by a batch Certificate of Analysis covering identity, moisture, menthol content (GC), microbiological parameters, pesticide residues (per EU Regulation 396/2005 MRLs), and heavy metals. Origin is disclosed per batch, and phytosanitary and country-of-origin documentation is provided as standard.

Peppermint for Herbal Tea Manufacturers

The Grade That Actually Matters for Tea Production

For herbal tea and infusion manufacturers, the single most important specification is cut-and-sifted (C/S) grade, not whole leaf and not powder. C/S peppermint passes through a defined sieve range — typically 1.4 mm to 5.6 mm particle size — which controls infusion rate, bag-fill weight consistency, and visual appeal in transparent sachets. Whole dried leaf is occasionally used for loose-leaf premium blends, but its bulk density variation creates problems for high-speed bagging lines. Powder (< 0.5 mm) is unsuitable for tea bags without specialist heat-sealed filter material and produces a cloudy, over-extracted liquor.

TANDOR sources peppermint in the following forms for this sector:

Cut-and-sifted (C/S) — standard tea-bag and pyramid-bag grade, sieve-specified on each order
Coarsely cut — for large-format pyramid bags and loose-leaf retail packs
Whole dried leaf — for premium loose-leaf and display infusions
Milled / TBC grade — available on request for functional blend matrices

Flavour & Colour Retention: Why Processing Method Decides Quality

Menthol content and chlorophyll integrity are the two measurable proxies for sensory quality in finished tea. Both degrade rapidly with excessive heat during drying, prolonged storage at humidity above 8 %, or aggressive sterilisation.

Moisture content should sit at or below 10 % (m/m) for stable shelf life — a threshold aligned with European Pharmacopoeia (Ph. Eur.) monograph 0405 for Menthae piperitae folium. Batches above this threshold risk mould proliferation and chlorophyll breakdown, producing a brown, hay-like product that underperforms in cup.

Menthol content is specified under Ph. Eur. 0405 and serves as the primary identity and potency marker. TANDOR's Certificate of Analysis for each batch includes GC-determined menthol and menthone values so blenders can standardise flavour intensity across supply runs.

Sterilisation: steam vs. irradiation is a critical procurement decision for EU herbal tea manufacturers:

Steam sterilisation (low-pressure steam) is the preferred method for colour- and flavour-sensitive tea grades. Correctly applied, it reduces microbial load without the structural degradation or regulatory complications associated with irradiation.
Irradiation is legally permitted in the EU under Directive 1999/2/EC and 1999/3/EC, but irradiated herbs must be labelled as such on finished products. Many retail buyers and private-label customers reject irradiated ingredients outright. TANDOR sources and clearly flags sterilisation method per batch, allowing manufacturers to specify their requirement at the point of enquiry.

Microbiological Standards for Tea-Grade Peppermint

Dried herbs intended for infusion are consumed without a further kill step, meaning the raw material itself carries the microbiological risk. EU-compliant tea-grade peppermint should meet — at minimum — the microbiological criteria aligned with EFSA guidance on dried herbs and spices and retailer-specific codes of practice (e.g. BRCGS Food Safety Standard):

Total Aerobic Count (TAC): typically ≤ 10⁵ CFU/g pre-sterilisation; post-sterilisation targets vary by customer specification
Enterobacteriaceae: ≤ 10² CFU/g
Salmonella spp.: absent in 25 g
E. coli: absent in 1 g
Yeast & mould: ≤ 10³ CFU/g

Every TANDOR batch CoA reports these parameters tested by an accredited third-party laboratory. Buyers who need tighter limits for immunocompromised-consumer products or pharmacopoeial-grade teas can specify those limits at enquiry stage.

EU-Organic Certification & Pesticide Compliance

Organic peppermint supplied by TANDOR is certified under EU Regulation 2018/848 on organic production, with valid organic certificates issued by an EU-accredited control body traceable to the farm or cooperative of origin. This certification is mandatory for any manufacturer intending to use the EU organic logo on finished packaging.

For conventional supply, pesticide residue compliance is governed by EU Regulation 396/2005 (maximum residue levels in herbs and spices). TANDOR batches are tested against MRLs prior to dispatch, with full pesticide screening results included in the CoA.

Additional certifications available on request:

ISO 22000 / FSSC 22000 supply chain documentation
Kosher and Halal certification (origin-dependent)
GACP-compliant harvest documentation for buyers supplying pharmaceutical or nutraceutical channels

Origin, MOQ & Sourcing Realities

Peppermint is cultivated across multiple EU and non-EU origins, each with distinct agronomic and sensory profiles:

Eastern Europe (Bulgaria, Romania, Poland): strong menthol character, good chlorophyll retention, EU-grown organic availability
Egypt: high-volume conventional supply, cost-competitive, strong menthol yield
India (Uttar Pradesh): globally dominant in volume, menthol-rich, requires thorough pesticide screening

As a Romania-based EU sourcing intermediary, TANDOR maintains relationships across these origins and selects supply based on the buyer's specification — not a single fixed origin. This multi-origin approach protects manufacturers against crop shortfalls, seasonal price swings, and quality inconsistencies from any single region.

Minimum order quantities are origin- and grade-dependent. EU-organic C/S peppermint typically moves from 100 kg per lot at TANDOR's scale; conventional C/S from 25 kg for sampling. Buyers are encouraged to request a specification sheet and sample before committing to volume.
