10-Year Production Trajectory: Rising Stars & Fading Producers
EU-27 chestnut output moved from a decade low of 263.9 thousand tonnes in 2016 to a peak of 324.1 thousand tonnes in 2020, closing at 321.2 thousand tonnes in 2025. Of the eight top producers, five recorded ascending trajectories, while three were stable — with no country showing a decisive declining trend.
Spain is the EU’s long-standing production leader, contributing between 49.8% and 62.4% of total EU output across the decade. Spanish production was remarkably steady, oscillating between a low of 156.2 thousand tonnes in 2017 and a high of 188.9 thousand tonnes in 2019, before closing at 160.1 thousand tonnes in 2025 (CAGR −0.12%, −1.7 thousand tonnes net, −1.0%). The 2025 value carries a provisional (p) flag. Spain’s 2018–2019 surge to 184.8–188.9 thousand tonnes marked the highest output of any single country in the decade, though this was followed by a gradual pullback to 2025 levels.
Italy is the decade’s most dynamic chestnut grower, more than doubling output from 33.7 thousand tonnes in 2016 to 83.5 thousand tonnes in 2025 (CAGR +10.63%, +49.9 thousand tonnes net, +148.2%). Italian production grew in eight of ten years, including a remarkable acceleration from 43.0 thousand tonnes in 2021 to 83.5 thousand tonnes in 2025 — an expansion of 94.2% in just four years. Italy’s share of EU production rose from 12.8% in 2016 to 26.0% in 2025, meaning it now supplies over a quarter of the bloc’s chestnuts. Greece, ranking third by cumulative production with 334.4 thousand tonnes over the decade, posted modest growth from 28.3 thousand tonnes to 35.5 thousand tonnes (CAGR +2.57%, +7.3 thousand tonnes net, +25.7%). All Greek values carry estimated (e) flags.
Portugal, once a close rival to Italy for the #2 slot, declined slightly from 32.1 thousand tonnes in 2016 to 29.9 thousand tonnes in 2025 (CAGR −0.79%, −2.2 thousand tonnes net, −6.9%). Portuguese production peaked at 43.8 thousand tonnes in 2019 before entering a sustained contraction — falling to 22.7 thousand tonnes by 2022 — followed by a partial recovery to 29.9 thousand tonnes in 2025 (flagged p). France grew steadily from 7.8 to 11.4 thousand tonnes (CAGR +4.31%, +3.6 thousand tonnes net, +46.2%), though the 2020 value carries a break-in-series (b) flag. Among the smaller producers, Hungary remained flat at 0.2 thousand tonnes, Slovenia quadrupled from 0.1 to 0.3 thousand tonnes (CAGR +18.40%), and Romania posted growth from near-zero output.

Supply Stability Scorecard: Reliability Rankings
Supply stability — measured by the coefficient of variation (CV%) — ranks Spain as the most reliable chestnut supplier among the top eight producers, with a CV of just 6.80% (very stable). Spain’s mean annual production of 175.81 thousand tonnes is more than three times that of the next-largest producer, and its years-below-mean count of 5 out of 10 reflects a balanced distribution. Spain’s maximum single-year drawdown of 11.94% — representing the worst harvest decline a buyer would have experienced — is the lowest in the cohort, reinforcing its status as an exceptionally dependable source.
Greece ranks second in stability (CV 8.85%, very stable), confirming that Greek chestnut output is highly predictable — bouncing within a tight 29.0–37.5 thousand tonnes range. However, all Greek values carry estimated (e) flags, so this stability is partly a reflection of data estimation rather than observed volatility. France ranks third (CV 16.21%, moderately stable) with a max drawdown of 22.31%. Hungary ranks fourth (CV 18.55%, moderately stable) despite tiny absolute output, while Portugal ranks fifth (CV 21.12%, volatile). Portugal’s max drawdown of 39.90% — the collapse from 43.8 thousand tonnes in 2019 to 22.7 thousand tonnes in 2022 — is the largest relative supply shock among Mediterranean producers.
Italy, the growth star, ranks only sixth in stability (CV 31.86%, volatile) with a max drawdown of 13.57%. While Italy’s drawdown is modest, its high CV reflects the sustained rapid upward trend — rapid growth translates mathematically into higher standard deviation. At the volatile extreme, Romania (CV 36.91%, rank 7) and Slovenia (CV 58.53%, rank 8) occupy the bottom positions. Slovenia’s extreme CV and max drawdown of 73.91% reflect the combination of a minuscule baseline (mean of 0.18 thousand tonnes) and explosive growth (+18.40% CAGR).
CV < 10% = Very stable, 10–20% = Moderately stable, > 20% = Volatile.

Land Allocation Shift: 10-Year Cropland Transformation
EU-27 harvested area for chestnuts expanded from 123.8 thousand hectares in 2016 to 146.7 thousand hectares in 2025 — a net gain of 22.9 thousand hectares (18.5%) at an annualized growth rate of 1.90%. Six of the eight major producers expanded area, with only Spain and Hungary contracting. The EU total area CAGR of 1.90% trails the production CAGR of 2.21%, signalling modest yield improvements across the bloc.
Portugal recorded the most significant absolute land expansion among the top eight, growing from 35.7 thousand hectares to 51.2 thousand hectares (+15.5 thousand hectares, +43.3%, annualized 4.07%). This is striking given Portugal’s production contraction (−0.79% CAGR) — area expanded enormously while output fell, implying Portuguese yields declined from approximately 0.90 t/ha in 2016 to 0.58 t/ha in 2025. The pattern is consistent with large-scale new plantings where young, immature trees are adding hectares but have not yet reached full bearing capacity. Italy expanded area from 34.5 to 39.7 thousand hectares (+5.3 thousand hectares, +15.3%, annualized 1.59%). Italy’s production CAGR of 10.63% vastly outran its area growth of 1.59%, indicating strong intensification — yields improved from approximately 0.98 t/ha in 2016 to 2.10 t/ha in 2025.
Greece expanded area modestly from 8.8 to 9.6 thousand hectares (+8.6%, annualized 0.93%), though all values carry estimated (e) flags. France added 1.2 thousand hectares to reach 9.3 thousand hectares (+14.7%, annualized 1.54%). Spain remained essentially flat (−1.4%). Among the smaller producers, Slovenia expanded from negligible area to 0.1 thousand hectares, Hungary contracted from 0.5 to 0.4 thousand hectares (−13.0%), and Romania maintained near-zero area throughout.
