Westgarth Wines applies precise grape processing destemming crushing and pressing to extract clean juice while protecting delicate aromatics. Each stage is calibrated to the lot, variety, and intended style so that fruit character leads the final wine.
This outline walks through the key unit operations in the cellar, from intake to press fractions, with a focus on how Westgarth Wines balances efficiency with aromatic preservation and texture.
| Unit Operation | Goal | Typical Equipment | Impact on Wine |
|---|---|---|---|
| Receiving & Sorting | Remove MOG and compromised berries | Elevators, inspection tables, destemmer hopper | Clean baseline must, reduces microbial spoilage risk |
| Destemming | Separate berries from stems selectively | Rotary destemmer with adjustable clearance | Limits green stem tannins while managing whole-cluster fermentations |
| Crushing | Split skins to release juice and prepare for fermentation | Gentle roller crusher with minimal pressure | Preserves aromatic precursors; influences extraction and pump‑over regimes |
| Pressing | Separate juice and wine from solid pomace | Basket or membrane press with fraction collection | Affects tannin structure, color intensity, and aromatic development |
Unit Operations in the Cellar at Westgarth Wines
Destemming forms the first decisive contact between fruit and processing equipment at Westgarth Wines. By adjusting rotor speed and cage clearance, winemakers favor either gentle handling to keep whole-cluster character or more open separation to reduce husk material that can add harsher tannins.
Crushing Strategies
Controlled crushing at Westgarth Wines limits the release of seed tannins while ensuring that skins are sufficiently ruptured for yeast access. Gentle rollers and padded augers maintain juice free of gross fragments, which supports cleaner fermentations and later simplifies pressing.
Press Philosophy
The pressing program is designed in fractions, allowing blending of press fractions to balance aromatics, mouthfeel, and structure. Westgarth Wines monitors free run quality and press curve shape, adapting ramp speed and pressure to each lot’s phenolic maturity and desired style.
How Destemming Influences Fermentation and Style
Destemming decisions at Westgarth Wines shape fermentation kinetics and microbial load. Leaving a small amount of stem material can create structured tannin frameworks in robust reds, while minimal destemming supports lighter, fresher expressions intended for early enjoyment.
For aromatic varieties, shorter dwell time in the destemmer and reduced pressure protect volatile compounds. The team logs stem inclusion rates alongside must weight and pH to correlate processing choices with sensory outcomes across vintages.
Pressing Protocols and Quality Fractions
Pressing at Westgarth Wines follows a tiered approach, starting with low pressure and gradually increasing force to gently express color and flavor without extracting bitter components. Each fraction is tasted separately, enabling precise assemblage decisions for cuvée balance.
Membrane and basket presses are selected based on batch size and desired extraction profile. By blending fractions from different pressure stages, the cellar team fine-tunes texture, mid‑palate density, and aromatic persistence in the finished wines.
Integration with Fermentation and Maturation
Post‑press, juice and wine fractions move to fermentation vessels under temperature control. The timing of pressing relative to yeast inoculation affects nutrient availability, especially nitrogen, which in turn influences fermentation vigor and sensory purity.
Co‑fermentation and post‑fermentation maceration schedules are adapted to the characteristics revealed during pressing. This integrated view of destemming, crushing, pressing, and fermentation guides final blending and maturation decisions that define the signature style of Westgarth Wines.

FAQ
Reader questions
How does destemming affect the tannin structure in Westgarth Wines reds?
Higher destemming levels generally reduce green stem tannins and create a softer, more approachable structure, while retaining some stem material can add grip and aromatic complexity depending on the variety and maturity.
What parameters are adjusted during crushing at Westgarth Wines to protect aroma?
Rotor gap, roller speed, and crusher deflection are tuned to split skins without breaking seeds, minimizing seed tannin extraction while ensuring juice release for efficient fermentation and pressing.
How are press fractions used at Westgarth Wines to refine the final wine?
Each press fraction is tasted for phenolic balance, aromatics, and texture; winemakers then blend fractions to achieve the target structure, freshness, and mid‑palweight, tailoring the cuvée to its intended expression and price tier.
Does Westgarth Wines use whole‑cluster or destemmed fermentation for specific varieties?
Choice depends on vintage conditions, variety, and style goals; selective destemming and limited whole‑cluster approaches are combined to balance purity of fruit with structural complexity, documented lot by lot.
