“…It was therefore more useful to evaluate the effect of climate change on the beverage attributes of acidity and flavor. Oberthür et al (2011) used CaNaSTA to subdivide the PDO of Colombian coffee. CaNaSTA (O'Brien et al 2004;Whitsed et al 2011) employs Bayesian statistics to define prior and conditional probability distributions and to combine these to calculate posterior probabilities for each possible outcome.…”

Coffee is grown in more than 60 tropical countries on over 11 million ha by an estimated 25 million farmers, most of whom are smallholders. Several regional studies demonstrate the climate sensitivity of coffee (Coffea arabica) and the likely impact of climate change on coffee suitability, yield, increased pest and disease pressure and farmers' livelihoods. The objectives of this paper are (i) to quantify the impact of progressive climate change to grow coffee and to produce high quality coffee in Nicaragua and (ii) to develop an adaptation framework across time and space to guide adaptation planning. We used coffee location and cup quality data from Nicaragua in combination with the Maxent and CaNaSTA crop suitability models, the WorldClim historical data and the CMIP3 global circulation models to predict the likely impact of climate change on coffee suitability and quality. We distinguished four different impact scenarios: Very high (coffee disappears), high (large negative changes), medium (little negative changes) and increase (positive changes) in climate suitability. During the Nicaraguan coffee roundtable, most promising adaptation strategies were identified, which we then used to develop a two-dimensional adaptation framework for coffee in time and space. Our analysis indicates that incremental adaptation may occur over

“…studied bilberries and blueberries grown at different altitudes in the Alps of northern Italy and observed that anthocyanins production was directly correlated to altitude. In coffee production, the terroir has a marked relevance and several studies were made on the interactions between cultivation area and aromatic profile . Oberthür et al ., showed how specific pedoclimatic conditions of different Colombia regions affected green coffee sensory properties.…”

Changes in chemical profile of Cascade hop cones according to the growing area

et al. 2019

BACKGROUND The growing area has a substantial effect on plants, affecting secondary metabolism. For hops, different authors have studied the effect of growing area on the chemical composition of cones with the aim of verifying and understanding the changes in hop characters. Despite the scant literature the subject receives increasing attention by brewers and hop growers. The present study aimed to characterize, using gas chromatography–mass spectrometry (GC–MS), and high‐performance liquid chromatography with ultraviolet detection (HPLC‐UV), cones of hop (Humulus lupulus L.) cultivar Cascade. Plant material was obtained from nine different areas of Italy and compared with Cascade samples grown in the United States, Germany and Slovenia. RESULTS Differences in bitter acids and xanthohumol content were observed. Nevertheless, no correlation between bitter acids and xanthohumol production, on the one hand, and rainfall, temperatures and latitude, on the other hand, were observed in our samples. The Slovenia samples were richer in molecules that confer hoppy, woody and flower notes; USA2 samples were more characterized by woody, earthy, grassy and floral aroma, quite different characters if compared to USA1, which had the lowest presence of grassy aromatic compounds. In the Italian samples, TRENTINO was the genotype most characterized by limonene presence. CONCLUSION The results of this study are indicative of the importance for hop users to know and characterize hops coming from different growing regions. The study pays special attention to the characterization of the differences in chemical characters of Cascade hop in Italy, where hop cultivation has developed only recently, but is in continuous expansion. © 2019 Society of Chemical Industry

“…By comparing C. arabica cultivars, cvs. Caturra) were grown in very similar production environments of the region, while the production environments were very different in Nariño, causing the differences in coffee bean composition (Oberthür et al, 2011). Conversely, annual crops of a specific cultivar were found to be significantly different in terms of total CGA content and individual isomer content.…”
