The Best Coffee Beans for the Sage Bambino Plus

The Sage Bambino Plus is one of the most popular home espresso machines in the UK, and for good reason. It produces genuinely excellent espresso at a price that was previously out of reach for most home setups. But a common frustration among new owners is that the first few shots disappoint. The machine gets blamed. Usually, the beans are the problem.

This guide covers exactly which type of beans work best in the Bambino Plus, why this machine behaves differently to cheaper options, and what to look for when buying.

What makes the Bambino Plus different from cheaper espresso machines

Most espresso machines under £200 use pressurised portafilter baskets. A pressurised basket creates extraction pressure artificially, which makes the machine forgiving of stale beans, inconsistent grinds, and the wrong roast level. You get something espresso-like regardless of what you put in.

The Bambino Plus uses a non-pressurised basket. The coffee puck itself has to create the back-pressure needed for proper extraction. This is how professional cafe machines work. It means the machine is more capable of producing real espresso, but it also means bean quality, freshness, and roast level all matter in a way they simply do not on cheaper machines.

The other significant difference is PID temperature control. The Bambino Plus holds its brewing temperature steadily at around 93°C shot after shot. Most machines at this price range do not have this. Temperature instability is why budget machines struggle with anything lighter than a dark roast. The Bambino Plus does not have that limitation, which opens up more options when choosing beans.

You also need a burr grinder

Before choosing beans, one practical point: the Bambino Plus does not have a built-in grinder. A blade grinder produces uneven grounds that extract inconsistently, and no bean choice will fix that. A burr grinder is necessary for this machine to perform properly. An entry-level electric burr grinder in the £100-150 range is enough to get excellent results. A manual burr grinder like the Timemore C3 works well for under £60 if budget is a constraint.

What roast level to use

• Dark roast — the most forgiving option. Extracts reliably through the non-pressurised basket with minimal grind precision needed. Best for milk-based drinks like flat whites and cappuccinos.
• Medium-dark roast — the sweet spot for most Bambino Plus owners. Works well black or with milk. The PID temperature control handles this roast consistently.
• Medium roast — works on the Bambino Plus better than on almost any other machine at this price. The stable temperature means medium single origins extract cleanly rather than coming out sour or flat.
• Light roast — possible but demanding. Requires a well-calibrated burr grinder and careful dialling in. Not the right starting point.

A note on freshness

Fresh beans are not optional on the Bambino Plus. The non-pressurised basket produces thin, pale shots with little crema when beans are stale. Most supermarket beans are routinely months old by the time they reach the shelf.

Caffé Prima is a UK roaster that roasts in small batches and ships direct. Beans arrive days after roasting rather than months, and the range covers every roast level relevant to the Bambino Plus. Prices start at £11.99 per kg, which is significantly below most specialty roasters. We have matched each bean in our range to the specific characteristics of the Bambino Plus below.

The best Caffé Prima beans for the Sage Bambino Plus

Here is how each roast level plays out in practice across our range, based on how the Bambino Plus specifically handles extraction.

Italian Mahogany (Dark roast)

Italian Mahogany is the best starting point for new Bambino Plus owners. It is the darkest roast in the Caffé Prima range, which makes it the most forgiving while you are still learning the machine and dialling in your grind. Dark roasts extract readily across a wider range of grind settings, so small errors produce less impact on the final shot. In the cup, it produces thick, stable crema with a cinder-toffee sweetness and clean cocoa finish. It holds its character through steamed milk, making it the strongest choice for flat whites and cappuccinos.

Continental (Medium-dark roast)

The Continental beans are a Brazilian Arabica and Vietnamese Robusta mix. The Robusta content is particularly relevant on the Bambino Plus: Robusta produces significantly more crema through a non-pressurised basket than through a pressurised one. Bambino Plus owners switching from cheaper machines often notice this immediately. It is a consistent, reliable bean that works well both as a straight espresso and in milk drinks, and it requires little adjustment between bags.

Espresso (Medium-dark roast)

The Espresso beans are a medium-dark roast from Brazil, Honduras, and Vietnam. It is the most versatile option in the range for this machine. The PID temperature control extracts it cleanly and consistently, producing balanced, sweet shots that work as a straight espresso, flat white, or Americano. If you drink different styles throughout the day and want one bean that handles all of them reliably, this is the one to use.

Colombian (Medium roast)

The Colombian beans are a single origin medium roast Arabica. On most home machines in this price range it is difficult to extract well — temperature instability causes it to run sour or flat. The Bambino Plus holds its temperature accurately enough that the Colombian comes out as it should: bright, clean, and full-bodied with a clarity that darker roasts cannot produce. Drink it black. Milk will mask the qualities that make it worth choosing.

Brazilian (Light roast)

The Brazilian beans are the most demanding bean in the Caffé Prima range on any machine, including the Bambino Plus. Light roasts are denser and require a finer grind and longer extraction time. The PID temperature control gives this bean a better chance here than on most home machines, but it still demands careful grind calibration. When extracted correctly it is sweet and delicate with almond notes and a clean finish. Get comfortable with the Espresso or Colombian first before trying this one.

Decaf Brazilian (Medium-dark roast)

The Decaf Brazilian uses CO2 processing, which removes caffeine without stripping the bean's natural flavour. It performs almost identically to the regular Espresso bean on the Bambino Plus: consistent extraction, good crema, and a smooth milk chocolate finish. It is the most practical afternoon or evening option for anyone reducing caffeine without wanting to sacrifice cup quality.

Decaf Espresso (Dark roast)

The Decaf Espresso uses Mountain Water and MC processing and is the bolder of the two decaf options. It extracts cleanly through the non-pressurised basket and holds its character through milk. If you want a proper-tasting cappuccino or flat white in the evening without the caffeine, this is the bean to use.

If your shots taste wrong

• Sour or sharp: grind finer. If using a light or medium roast, consider moving to a medium-dark while you dial in your grind.
• Bitter: grind coarser.
• Weak and watery: the shot is running too fast. Tighten the grind or increase your dose slightly.
• No crema: beans are stale. Check the roast date. Beans more than six weeks past roasting will not produce meaningful crema through a non-pressurised basket.

Where to start

If you have just bought the Bambino Plus and want one bag to begin with, start with Italian Mahogany. It is the most forgiving bean in our range on this machine, produces excellent results from day one, and works across every drink the Bambino Plus can make. Once you are comfortable with your grind setting and shot timing, move to the Espresso bean for a more balanced daily option, or the Colombian if you drink your coffee black and want something brighter. The machine is capable of all of it. The beans just need to match what you are asking it to do.
