DPG Consulting

Winemaking guidance by Dan Piwko-Graham — Founder of Sigurd Wines

With over 22 years of experience and more than 40 vintages across Australia, Europe, New Zealand and North America, I help wineries craft wines that express their site clearly and honestly. DPG Consulting is my way of working with boutique and mid-sized producers who want to refine their wines and strengthen their cellar work without losing their own identity.

Everything is collaborative and shaped by experience - whether it’s structured Bordeaux varieties or low-intervention ferments.
I’m not here to change your style.
I’m here to help your vineyard say what it’s trying to say.

Calm Guidance

20+ years, 40+ vintages of experience.

Support That Strengthens Your Team

Practical mentoring, confident decision-making and problem-solving.

True to Place

From pick calls to blending and bottling, I help shape wines that feel honest, expressive, and true to the vineyard.



1. One-Off Consult

Sometimes you just need another palate in the room - someone who’s been through a few seasons and can see things clearly. A ferment that’s stuck, a pick call you’re unsure about, or simply a tasting to help you trust your instincts. Simple, direct support. Honest guidance when you need it.

  • Fermentation strategy
  • Blending and style development
  • Quality control and troubleshooting

2. Harvest time support

Some moments shape the whole season - the planning, the picking, the steady decisions that guide a wine from fruit to ferment to bottle. Here, I work alongside you for a defined project, helping refine style and strengthen the flow of your cellar.

  • Harvest planning and grape readiness
  • Fermentation strategy and vessel selection
  • Blending and style development
  • Bottling and finishing support

3. Ongoing partnership

Some things take time - confidence, consistency, and a clear sense of where your wines are heading. This long-term support sits alongside your work in a steady, practical way, helping your team grow and your wines evolve naturally, season after season.

  • Vineyard and site assessment
  • Ageing and maturation planning
  • Team training and cellar staff mentoring
  • Production compliance and documentation
  • Sustainability and innovation in process

'We believe this care and respect for the earth translates into plant, process and product.'
